Opines that close to where the point of percussion occurs is the "sweet spot." Explains that a net force hit on small mass will go farther than large mass. A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. As a result, the fundamental and second vibration modes are both excited with about the same amplitude. This is similarly done for tennis rackets and baseball bats. And we end up with 12.6 meters per second , Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as the , Summary. (function() { Other research indicates that the 'sweet spot' lies between the nodes of the lowest 2 vibrations of the bat. When a wake is pushed down, a fastball is pushed up. 2) Choose the right turn model As discussed earlier, a wider handle will improve bat durability and reduce the likelihood of breakage. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. But I would expect there to be a difference.. It is not quantum physics or relativity, but a very interesting problem involving the mechanics of colliding objects. This is due to the fact that the collision is able to create a larger transfer of energy when the bat and ball are in perfect alignment. } << Since it's vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesn't cause the bat to. I simply wanted to know whether a hand launched ball spins at around 100 rpm or whether it could be as high as 1000 rpm. Results for a baseball dropped from heights of 1, 5, 10 and 15 cm onto a piezo are shown below. Despite the old timey aesthetic to wooden bats and sweet spots, scientists actually didnt know much of anything about the acoustics (yes, acoustics) of a bat until the 1980s and 90s. Is it possible to hit heavier bats harder? On average, players aged 15 to 17 hit 140 feet, while players aged 16 to 18 hit 150 feet, and players aged 18 to 19 hit 165 feet. If the ball is at rest (when striking a ball off a T ) then. Newtons second law, which deals with the value of time, is also important in baseball. I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. The end result can be a greater ball speed off the bat, in the same way that a tennis ball bounces a lot better off tennis strings than off a hard floor. @L`YKUJNGBP\poR=_;Dl'P(T There's no stinging, no vibration and no broken bat. Hey, were not all headed to the majors. The Sweet Science. We can then ask a similar question. This is the location of the bat that is generally regarded as the best spot for hitting the ball. The weight drop of a baseball bat is the difference between a bats length and its weight in ounces, which is the difference between a bats length and weight in ounces. In bats made of maple wood, like the Axe Bat, it's easy to find the strongest grain. Magnetism is also an important aspect of baseball because bats use magnetite, a magnetic substance found in the body, as a means of internal navigation. /V 6 0 R Published Mar 30, 2018 4:11 PM EDT. ); An aluminum bat is much lighter than a wooden bat, increasing its range and allowing it to hit the ball farther. 13 0 obj When you are evaluating their soft toss performance, you can also look at how heavy a bat they should be. 25 0 obj A simple introduction to the physics of the collision problem is given here. >> Initially, the force on the handle is in the opposite direction to the motion of the handle. Each type of wood has its own unique characteristics, making it important for players to consider the type of wood when selecting a bat. R. Cross, Physics of Baseball & Softball, DOI 10.1007/978-1-4419-8113-4 14, c Springer Science+Business . Definition. While the majority of baseball bats are constructed from wood, there are also metal alloy bats available for certain leagues. endobj One was a 232 gram broomstick, one was a 871 gram Louisville Slugger wood bat with four holes drilled through the barrel, and one was the 871 gram bat increased to 1333 gram by inserting a steel bolt through each hole. The physics of a baseball bat include the material of the bat, the length, weight, and shape of the bat, and the force of the swing. /R [52 73 308 791 ] A careful analysis of baseball dynamics shows that this special spot is located at the point where an applied force would result in pure rotation of the bat about the handle grip. Curve Balls Sweet Spot / Corked Bats / Questec-MLB Zone Evaluation. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. But man, hit it right on the sweet spot and it feels like you are a baseball god. See, the trouble with wood is that it vibrates. Sara Chodosh For further details, see American Journal of Physics, September 1998 and also American Journal of Physics, 69, 231-232 (2001). As Russell explained before, there are two related ideals that we conflate into one sweet spot. In theory, the ball bounces best for an impact at the center of mass of the bat, provided we can ignore bat vibrations. The mode shape of a baseball or softball bat is a simple flexing bending shape that has parts that move and parts that don't. Every bat has a point about seven inches in from the tip of the bat that doesn't move, that doesn't vibrate, called a node. 2. If there was no loss of energy during the bounce then COR would be 1.0. /R [316 73 572 791 ] the location where maximum energy is transferred to the ball. /Filter [/ASCII85Decode /LZWDecode ] Each baseball bat has a sweet spot due to vibrational physics. The sweet spot (where you want to hit the ball consistently) is located about 2 in from the end of the barrel to about 6-7 in on an adult bat. The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. 12 0 obj The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. A ball that strikes the bat does not cause it to vibrate at this point. >> Its just $1 per month , By The 232 g bat was swung at 45 radians/sec on average (by the batter in the film). Its center of mass is 52.6 cm from the knob end. To understand such collisions it is important to first understand the physics of a collision between one ball and another. At the major league level, maple bats now account for 75% to 80% of all bats. << The three elements of a game of baseball are critical, and the game is built around Newtons laws of motion. Wood bats hit farther than metal bats, which is the clear distinction between them. Metal bats have the distinct composition of wood bats and the balance of pop and density that wood bats lack, whereas wood bats fly faster and farther when hit by wood bats. This includes both the length of the barreltop part of the batand its diameter The longer the barrel, generally, the larger the sweet spot for hitting the ball The standard diameter is 2 , and big barrel bats, allowed in some leagues, are 2 5/8. Hitting a ball incorrectly can make a wooden bat break due to the grain of the wood. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. I havent listened to different recordings of hits to see if theres a noticeable difference, says Russell. Players tend to feel a zing in their hands; often called bat sting. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. Baseball bats are an integral part of the game of baseball, and their physics is an important aspect of the sport. } The bat was swung through an angle of about 30 degrees to strike the ball. In file A, the ball spins faster than in file B, both before and after the bounce. At other impact points, the impact is usually felt as a sting or jarring of the hands and forearm, particularly if the impact occurs at a point well removed from the sweet spot. A batsman during a cricket game aiming his shot to hit the sweet spot of the bat. The cookie is used to store the user consent for the cookies in the category "Other. Recent Research Highlights. The above results are more or less as expected, in that light bats can be swung faster than heavy bats. One of these sweet spots relates to vibration. >> A 28-inch bat should be ideal for anyone weighing 61 pounds or more who has a height of between 61 and 80 pounds. If you drop the weight, you will be able to use the bat with greater control and power. Bat speed depends on MOI, and is an important component of laboratory performance tests. This is not an easy rating to obtain. When a batter hits a ball, the bat will rebound from the force of the collision. So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. If you hit . In addition to the second law, we can understand how the force of the bat affects a balls motion. Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. In order to determine how each of the sweet spots influences the "feel" of the bat, measurements were made of the impact forces transmitted to the hands. /P 8 0 R The hitch is, no one knows for sure how close the optimal spot for hitting is to the sweet spot that players know and love. How Many Square Inches Of Orange Does It Take To Cover A Baseball Cap? Although most baseball players may not know the deep details, they usually understand that it is not just the skill and effort they put into their swing, but also the specifications of their baseball bat which will impact the success of the hit. 22 0 obj In any collision, energy from both objects gets transferred around, but in a swing your goal is to put as much energy as possible back into the baseball. gF/(+GaKo$qneLWDrQ#;5\S(\$q'LM9bYJX9N;hHO_e;>`Y"/'J:I~> The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. For a tennis racquet only the fundamental mode of vibration is excited by the impact since the impact duration, about 5 msec, is too long to excite higher frequency modes of the racquet. endobj A great way to keep a rhythm throughout your swing is to step or stride toward the pitcher. /N 27 0 R Allow Dan Russell to explain: Any solid structure has vibrational patterns.. Nathan hopes to test the theory of Robert Adair, a Yale University physics professor and baseball guru, who believes the subjective sweet spot sits on the node where the bat's lowest frequency vibrations drop out. /V 22 0 R The vibration of the bat takes energy away from the ball. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. The Physics of Baseball. Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. That said, composite and metal bats are still used by younger players who are still developing their skills. The ball is spinning clockwise before it bounces and hits the granite block with backspin. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. As a result, the bounce is relatively weak at the tip and near the center of mass. The true CoP should be measured from that point. /P 20 0 R It was found, by measuring the frequencies of lots of aluminum tubes (see photo). Ball exit speed = q*vin where vin = incident ball speed. Largest thickness - The sweet spot Bat - Ball Collision Diagrams Vball 1 = Vb Vbat 1 = V2b V bat 2 = V2a Vball = V1a Before After The node is related to where the sweet spot is - where the bat does NOT bend or vibrate. After completing his degree, George worked as a postdoctoral researcher at CERN, the world's largest particle physics laboratory. /R [316 74 572 585 ] It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. A superball has a COR of about 0.9, a baseball has a COR of about 0.5 and a sorbothane ball has a COR of about 0.1 (ie it hardly bounces at all). /V 15 0 R The idea is to mount a bat as a pendulum and strike it with a ball at various spots along the barrel. Energy is lost during the collision if the bat vibrates. The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. A hollow aluminum bat sounds a lot different to a solid bat since the wall of a hollow bat can vibrate in and out like a drum. There is no set formula. The experiment described below would be an ideal project on the physics of baseball, for any high school or University physics student. Well also examine the impact that technology has had on the design of baseball bats in recent years and how it has helped players to hit the ball farther and harder. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. The same thing happens when swinging a golf club, but it is not a well-known effect. An impact at the fundamental node will not excite that mode, but it will excite the second mode. A light bat can help with dry swing training, as it can be more effective and less strenuous. The Physics of Baseball Bat Sweet-Spot. >> The flight of a ball through the air depends strongly on how fast it spins, and in what direction it spins. | A paper on this subject can be downloaded here. For a fastball, this wake gets pushed down, which then pushes the ball up .. How do you control where to hit a baseball? /R [52 73 308 791 ] The length and weight of a bat is tailored to the size, strength and hitting style of the individual player. 5 0 obj Learn how the sweet spot correlates with movement and vibration. throughout the paper. A pitch produces a turbulent wake of air behind the ball. The outgoing speed of the ball is just the sum of the two separate parts - the speed when the bat is at rest plus the speed when the ball is at rest. When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second - the impact could mean up to 5,000 lbs of force. endobj Thats the sweet spot. When a player has a bad hit and fails to hit the "sweet spot", it causes vibrations which can cause the bat to bend or break. Where is the sweet spot on a bat? /V 16 0 R In order to determine how each of the sweet spots Expand 71 PDF An investigation into the power point in tennis S. Choppin Education 2013 Registration on or use of this site constitutes acceptance of our Terms of Service. 9 0 obj The ideal is the 110 turn model. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. Furthermore, the tip is the lightest and least effective part of the bat. It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. The force of the swing is also a key factor in the performance of a baseball bat, as a hard swing can generate more power, while a softer swing can produce more control. However, there are many variables in experiments like these. Two ounces doesnt seem like much but Ive seen it make a large difference. endobj Potential energy is what might be called stored energy. The first is where the bat feels best in your hands when you hit. Then can't we add to the list of deeper queries some of . Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. /Gamma [1.8 1.8 1.8] /Length 996 The vibration modes of a baseball bat are easily determined,3-5at least for a freely suspended bat ~e.g., one that is suspended by a light string!. The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. Share your thoughts with us below! The experiment can be done at low bat and ball speeds since the essential physics of the problem does not depend on the actual bat and ball speeds. [/CalRGB Demonstrating the sweet spot of the bat in a talk I gave at Wrigley Field for University of Illinois alumni in 1997. The cookie is used to store the user consent for the cookies in the category "Analytics". This website uses cookies to improve your experience while you navigate through the website. The faster the hit ball travels, the longer it should travel. When a pitch is played, a turbulent stream of air runs behind the ball. And we divide that by Pi times 9.00 centimeters written as meters so centi is prefix meaning ten times minus two and we square that diameter. The sweet spots location for maximizing how far the batted ball travels after being hit can be calculated scientifically. endobj endobj /V 5 0 R /R [52 74 308 585 ] The cookies is used to store the user consent for the cookies in the category "Necessary". A similar question: The bumper on a pool table is at a height so that the pool ball does not skid when it hits it. Each impact was recorded on a video camera at 25 frames/sec. The dead spots in the bat will cause a vibration to be sent down through the handle of the bat into the hands, which ultimately causes vibration or a stinging feeling. If you are 91 to 120 pounds, it is recommended that you use a 29-inch bat. Sniper Skin carries a line of great bat grips which are easy to install and remove while virtually eliminating the sticky gunk left on your bat. READ SOMETHING ELSE Table of Contentsshow Lloyd Smith at Washington State University has an excellent site on the physics and engineering of softball, at http://www.mme.wsu.edu/~ssl , including information on how bats and balls are tested and certified for use in the USA. The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. /Length 459 Theres one where it feels good in your hands, one where the ball comes off the fastest. The collision of a bat and a ball can be understood by treating the bat as a heavy ball whose mass depends on the impact point. The batter exerts some 6000-8000 pounds of force on the ball. More comparisons can be made by adding more information. While the center of mass moves one way (nearly upward here), the handle moves the opposite way (nearly downward). on: function(evt, cb) { When it comes to the distance traveled by a ball, speed and speed at which it sails off the bat are all important factors. Just look for ovals going around each other. /R as well as the force at right angles to that, given by M (dV/dt). First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. In general, swing weight increases with actual weight, but swing weight also depends on bat length and weight distribution. How is this described in Mechanics? /I << event : evt, At one point, called the node, the waves always cancel each other out. The node sweet spot differs from the center of percussion sweet spot. ** A new article on knuckleballs was added in May 2013 **. /P 17 0 R Where is the best place on a bat to hit the ball? According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . The ratio of ball speeds after and before colliding with the bat is called the is combined with the kinematic properties of the bat (determined from the moment-of-inertia of the bat and the impact location) to obtain the Bat-Ball Coefficient-of-Restitution, or BBCOR for the collosion. Near the end of the swing, the bat swings so fast that the batter can no longer keep his wrists locked, and the centripital force on the bat is about equal to the weight of the batter. Maple and ash are the most commonly used materials in major league baseball. The illumination of the ordinaryof why the sky is blue or why the stars shineis not the least important role of physics and physicists. The heavier the bat, the higher the bats bat speed. So, after a rainy day game, ensure your bat is dry before you store it. A bat that is too light also hampers the development of a solid, level swing. This is why it is important that baseball bats are made out of a hard material that can maximize the energy transfer while also reducing the risk of injury to the player. /N 22 0 R There is a significant difference between end-load and balanced softball bats in terms of weight distribution. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. It is almost as easy as walking. /R [316 73 572 791 ] If the ball is struck at the sweet spot of the bat, then . Good eyesight. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. << However, the centripetal force does not act along the axis of the bat, but at an angle, as shown by the orange lines. Softer and less dense varieties of maple that are more likely to break have been banned by Major League Baseball. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. It is almost as easy as walking. /Filter /LZWDecode window.mc4wp = window.mc4wp || { Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. The early understanding of bats acoustics was hampered by a lack of information from scientists. When a player has a bad hit and fails to hit the sweet spot, it causes vibrations which can cause the bat to bend or break. Wood bats and aluminum bats have their own set of advantages and disadvantages, and the choice for the player is based on preference. When you hit a ball just right, you've hit it on one of the three "sweet spots" of the bat. Graphs of F vs t and x vs t can also be used to generate graphs of F vs x, showing how the force on the ball varies with its compression. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. /Matrix [0.4497 0.2446 0.02518 0.3163 0.672 0.1412 0.1845 0.08334 0.9227] 15 0 obj /R [52 73 308 791 ] The size and weight of the bat is a matter of personal preference, but it is important to remember that a bat must be approved by the league in order to be used in official games.
