Does cleaning a table tennis racket and keeping it in a case preserve its power and spin?

Introduction:
Spin plays a large part in most, if not all, ball sports. In no sport is the Magnus Effect more conspicuous than in the sport of table tennis. The small, light ball can spin up to 150 revolutions per second in a match situation. (Qun, et al., 1992) This is due largely to technique, but the level of spin has greatly improved since the 1950’s, due to the invent of “sandwich rubber”, or “Inverted rubber” (see Figure 1), as opposed to the old pimpled rubbers (Figure 2). This greatly increased surface area and spin changed the sport and history, as players now looked to optimise the spin of their rackets. After years of playing with glues to

When the ball makes contact with the racket, the ball grips to the racket. This means a certain point of the ball stops, as the ball begins to turn away from the racket, as the ball naturally keeps spinning (due to inertia). Because this ball has gripped, the angle of reflection changes, becoming what is known as the throw angle.

Hypothesis:
Cleaning a table tennis racket and keeping it in a case will significantly preserve its playing characteristics (power and spin). Leaving a racket in the sun will severely decrease both spin and power.

Risk Assessment:
There are no particularly dangerous items used in this experiment, but table tennis balls will be launched at high speeds, so common sense around the equipment is required to prevent injuries caused by slipping on table tennis balls or similar injuries.

Apparatus:
5 Regail brand table tennis rackets were used as tested rubber surfaces.
3 star (top quality) ITTF Approved Double Fish table tennis balls were shot at the rackets. 1 Double Fish Ball-Launching Table Tennis Robot fired the balls towards the racket with topspin.
1 Casio camera (capable of filming at 240fps) was used in recording the

    Biomechanical principles are what introduces the human body to motion, so the tennis biomechanics is essentially the science mechanics tennis technique. Tennis is a game in which two or more players hit the ball with rackets over a low net that is stretched across a court which is usually artificial surface. The tennis serve begins from the feet hitting the ground then continues up through the torso to the shoulders, then moves to the arm and then wrist. It continues right to the point when the ball hits the racquet. The objective of tennis is to hit the ball from one end of the court to another without getting it out of the bounds.…

    Tennis is a highly competitive sport with participation in over 200 countries throughout the world. It is a non-contact racquet sport which requires aspects such as strength, power, speed, coordination and agility. Like any sport, tennis places specific demands on the body which can predispose any player to injury. These demands placed on the body result in injuries specific to the game. It is said by Pluim et al (2006) that although many injuries that occur in tennis are common in other sports, tennis has its own unique profile of injuries. (1) Injuries such as lateral ankle sprains, calf strains, lower back pain, tennis toe, shoulder impingement, lateral epicondylitis (tennis elbow), ulnar collateral ligament tears and wrist strains are all…

    Overview: In this lab, we will test balls made of various materials. The matter that composes the ball must store energy on impact and then release the energy in a way that allows elastic recoil, or bounce. In addition to elasticity, there is also a relationship between the height from which the ball is dropped and the height of the bounce. We will measure and graph the relationship of those two variables.…

    Many people know what a tennis racket is, it is used as a extended arm for hitting the tennis ball to the other side of the court (opponents side) to score. During the old days of tennis, about 900 years ago, people have been using their hand as a tennis racket, but it is evolved to pallas then wooden rackets, but the pallas and wooden rackets are really hard to control since it only have a really small racket head size so that it will be harder to hit the sweet spot (center) to have more accuracy on the ball. But after the new/ modern tennis “Graphite racket” was invented, we can now have more control, more accuracy, more spin, more speed for the shots. (GGN. (2011). Evolution of the Tennis Racquet) Now let’s look at how it relates to the Newton’s Laws of Motion.…

    A teenager named Naya Menezes was simply concerned about her peers and close friends. She was seeing many soccer players getting head injuries on the field and wanted to do something about it. Naya came up with the idea of testing different types of headgear, to see exactly what was protective and what you could do without. In order to do this she needed the types of headgear and something to test it on, which later ended up being a mannequin. She put an accelerometer in the mannequin's head to measure how far back the mannequin moved back because of the ball’s force. To throw the ball Naya used one of the devices that shoots tennis balls. She had the machine shoot the balls in speeds varying from 40 to 65 miles per hour.…

    During the course of the preparation phase my weight is initially shifted from the front foot to the rear foot. Concurrently the left arm tosses the ball, consistency is imperative in the motion to the performance of the serve. It is important for a consistent toss, to have the left arm extended throughout the toss looking across from me somewhat poor mechanics. My elbow slightly flexed and extends the arm, rotating it from the shoulder, across my body from my outside hip. The left arm carries up to a fully extended position and aids concentration on the ball. This action occurs in order to counter the action of the racquet arm, which is moving to the rear of the body. The action of the non-racquet and racquet arm is an example of Newton’s third law, which states that every action has an equal and opposite reaction. The action of the left arm balances that of the right arm so that the racquet arm does not initiate unwanted angular momentum. As the action of the arms and torso occur the weight is shifted from the rear leg back to the front leg and the knees are bent in order to store potential energy. Notice the degree to which I bends my knees in above pictures, this enables my to generate more thrust against the ground therefore generating a more swing. This concept is known as ground reaction force. As I begin to develop consistency in my serve and begin increasing its power, I will have to start bending my knees more in order to store up more potential energy in an attempt to produce a more powerful serves. My hips shift forward, also as a result of Newton’s third law. The action of the arms and torso to the rear is equal and opposite to the hips shifting forward. The body therefore maintains balance and allows the body to flex further backward, storing more strain energy and increasing impulse. I flexes my arm almost too horizontal which a powerful swing to my serve. As a result of this my non racquet arm is extended to counter react and keep…

    The most commonly recognized governing body for pocket billiards in the United States today is the Billiards Congress of America (BCA). The rules and standards established by the BCA are the basis for all billiards games played in this country today. Equipment standards are adhered to by amateurs and professionals alike although, professional standards are slightly more limiting. Pocket billiards is played on a table that is half as wide as it is long and has 6 pockets. The balls used in the game consist of one white ball “the cue ball,” and 15 colored balls numbered 1 thru 15, the 1 thru 8 are a solid colored and referred to as “solids” or “little ones” the 9 thru 15 are white with a solid colored stripe around the ball and are referred to as “stripes” or “big ones.” The cue stick usually referred to as simply a “cue” or “stick,” used…

    To be successful in the game of tennis is dependent on the player’s technique as well as biomechanics which play a vital role in stroke production. A fundamental mechanical structure is founds in all tennis strokes.11 The backswing provides the distance. Tennis players need to be able to control the direction of the racket and the timing of the entire movement. The skill level of the tennis player depends largely on the mechanics of their forehand swing. The force of impact is determined by the racket speed at the moment it comes in contact with the ball. When maximum distance is used for accelerating that is when maximum velocity can be obtained. Body weight support is necessary for the forehand drive because shifting weight when striking the ball will increase ground reaction force to the body and the ball. A player wants to be balanced to direct power and energy without losing control. Forward momentum will carry the racket through the ball after contact. The follow through helps prepare the player for the next stroke. It should be long and the arm and racket should wrap around the body. It dissipates kinetic energy off the racket and that is when the player wants to arrive at the right point and balanced to be ready for the next stroke and to be able to play the ball back. The player’s body must absorb the remaining energy of the racket and the…

    However, in today’s game the rackets weigh about 200 grams. A racket that is heavier is harder to swing and harder to control giving less control to the tennis player. Another vital property of a racket is the bending stiffness, which affects the collision on the ball and the racket. Flexible rackets bend far more on impact compared to a stiff racket that will not bend very much. More energy is absorbed by the flexible racket, with more of the energy going into the bending of the material. Stiff rackets are generally more powerful as less energy is lost in the bending of the racket therefore more energy can be returned to the ball through the strings. In order to maximise the bending stiffness, young’s modulus has to be found out. As you apply tensile stress to the material, the material elongates. Stress is defined as the load per unit area and is measured in Pascal’s. The ratio between the original length and the change in length when a load is applied is called the strain. After the materials and properties are considered, the manufacturing process…
