Introduction: When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions
strings changes the stability of a network. This property of strings was used to improve the performances of tennis racquets. It is hard to define “power” of racquet. According to [4] power could be defined as 1. racquet bounce (high coefficient of restitution) 2. high swing weight (high angular
Investigating the Bounce of a Tennis Ball after It Has Been Dropped From Certain Height Aim To investigate how high a tennis ball will bounce back after it has been dropped from a certain height How a Tennis Ball Bounces As the ball is elevated the ball gains gravitational potential energy equal to the ball's weight multiplied by its change in height1. When the ball is dropped, the height decreases, and therefore so does the gravitational potential energy. At the same time, the velocity
generates more friction that a smooth surface, like the other two balls. (Bowden, 1951, pg. 302; Tremaine and Weinberg, 1984) Secondly, published coefficient of restitution values varied considerably depending on the source. It is easier to calculate coefficient of restitution values experimentally rather than theoretically, therefore coefficient of restitution values can vary from source to source (Elert, 2006). Thus, the accuracy of these values is poor, and the calculated velocity is equally poor.
Avid golfers know all too well the elusive nature of the golf club’s sweet spot. It is a mystery they spend hours trying to solve on the links, usually to no avail. What sets apart amateurs from the professionals is the ability to consistently strike the highly critical pinpoint portion of the club. It is easy to see the difference between the consistency of an amateur and a professional with the definition of the wear spots on the pro’s golf club located where the sweet spot should be (see figure
taken to limiting the number of home runs a team can hit.” (Jay Greene 2,3) Even in the second article with the statement, “The higher we can get the COR, the faster the ball would shoot off from the “collision” – it would go further.” (Coefficient of Restitution 2,1) Lastly in the third article when the author stated, “Clearly, pole-vaulting is an example of a sport in which technology has been used to improve athletic performance.” (The Physics of pole-vaulting ) Without physics these technological
1.0 Background Theory 1.1 Introduction This investigation aims to determine the ideal air pressure inside and the ideal material of a ball in order for that ball to achieve its greatest bounce height. This report will be focusing on how the air pressure and material of a soccer ball, basketball and volleyball affects the bounce height of each ball. 1.2 Research Question 1. How does the air pressure inside a ball influence the bounce height/vertical motion of that ball? 2. How does the material of
Investigating the Effect of Temperature on the Height a Squash Ball Bounce Aim: To investigate the effect of temperature on the height a squash ball bounces. Prediction: I think that the higher the temperature of the squash ball, the higher the squash ball will bounce. I think that as the temperature doubles so will the height of the bounce. I think that they will be directly proportional. Scientific Knowledge: If you drop a ball onto a hard floor. It will rebound, but even the bounciest
1 Introduction 1.1 Granular Flow Granular flow is a phenomenon of significant importance in industries and nature. Granular material is a solid matter which consists of many individual small particles. Movement of particle assemblies can be understood as granular flows. In granular flows, direct particle-particle interactions are dominant.
impact between the club head and the golf ball there is large force acting on the ball which causes it to deform. A player will ideally want to launch the ball in the highest possible speed. The one value we can measure for deformation is the coefficient of restitution (further on as ‘COR’). The COR is defined as the ability of one object to transfer energy to another at impact, between 0.0 for perfectly inelastic collision and 1.0 for perfectly elastic. In golf, it describes the ability of the golf club
1.0 Introduction A golf ball is a spherical ball with dimples on surface that specially designed to be used in a game of “golf”. The currently used material for the core body is rubber. Polybutediene rubber is synthetic rubber which is tough but elastic like the tires’ properties, this explains why most of the ball speed is due to the rubber core properties. The inner cover of golf ball is usually made up of surlyn, but sometime surlyn also made up the outer cover of golf ball. Surlyn is an ionomer
Every ball player, whether they realize it or not, is a mathematician or physicist. Baseball, the infamous favorite pass time of the United States, is full of physics laws and principals. It is easy to think that all these players do is throw around a ball, occasionally hit it, run around some bases, and make a great catch. However, baseball has many underlying complex principals that can be explained through the laws physics. It encompasses all three planes of motion with players exhibiting the
validity, which explains whether or not theoretical relationships can be determined, and discriminant validity, which explains to what degree subjects, can differentiate between variables or topics. According to Meyer (1996), “The convergent validity coefficient between the cohesion scale on the FES and the cohesion scale on FACES II was significant at .74” (Abstract section). Numerous studies have addressed construct and discriminant validity of this scale. According to the FES (n.d), the manual describes
According to the ESPN.com the average major league baseball team is worth 744 million dollars. The average team went up 23 percent from the 2012 season. The MLB media generates more than 600 million dollars in revenue. The national television revenue for baseball is around 12.4 billion dollars including, Fox, and ESPN. The average major league baseball player makes 3.31 million dollars a year, which is the second highest paid players of the four major sports leagues, according to yahoo.com. In order
CHAPTER 2 LITERATURE REVIEW 2.1 CHAPTER OVERVIEW Good “feel,” (high resilience), high abrasion resistance and high spin are the desirable quantities that offered by the modern ball compared to previous golf ball. A good golf ball must “feel” soft to the golfer, but must be resilient enough to rebound to its original shape and hardness after the momentary deformation that necessarily results after being struck repeatedly with a force that can equal 10,000 N. The “feel” is thought to be attributed
Callaway Golf Company History Callaway Golf Company CEO Ron Drapeau told CBSMarketWatch, "We have become known as the company that brings innovation to the game for the average golfer. We're not focused on the elite professional players. It's been a very successful approach for us." But that is not to say that Callaway clubs are spurned by professionals. By the end of the 2000 professional tour, Callaway Golf ranked as the most-played manufacturer of drivers, fairway woods and irons on the world's
result from impulses, external forces acting over a time interval. The elasticity of an impact governs the amount of velocity present in the system following the impact. The relative elasticity of two affecting body is represented by the coefficient of restitutions. Mechanical work is the product of force and the distance through which the force acts. Mechanical power is the mechanical work done over a time interval. Mechanical energy has two major forms; kinetics and potential. When gravity is the
Investigating the Bounce of a Squash Ball This investigation is associated with the bounce of a squash ball. I will be investigating 4 different types of squash balls, which have different, bounce properties and compare them to each other and relate them to why each different type of squash ball is used. The relationship will be associated with how different balls are used at different levels of proficiency in the game of squash i.e. the squash balls that don't bounce much will probably
