Many people know what a tennis racket is. it is used as a drawn-out arm for hitting the tennis ball to the other side of the tribunal ( oppositions side ) to hit. During the old yearss of tennis. about 900 old ages ago. people have been utilizing their manus as a tennis racket. but it is evolved to pallas so wooden rackets. but the Athenas and wooden rackets are truly difficult to command since it merely have a truly little racket caput size so that it will be harder to hit the sweet topographic point ( centre ) to hold more truth on the ball. But after the new/ modern tennis “Graphite racket” was invented. we can now hold more control. more truth. more spin. more velocity for the shootings. ( GGN. ( 2011 ) . Development of the Tennis Racquet ) Now let’s expression at how it relates to the Newton’s Laws of Motion.
A tennis racket is really related to the newton’s 3rd jurisprudence of gesture – “for every action. there is a equal or opposite reaction. the expression is F1=F2” . ( Henderson. T. ( 2011 December 11 ) . Newtons Third Law ) It is related because when a tennis ball is coming towards you from your opposition in a changeless speed ( non numbering how the air current and air opposition ) . and so you utilizing your racket ( F1 ) to hit/ act upon the ball and the tennis ball ( F2 ) will travel to the equal velocity and way as the racket ( F1 ) . and the harder you swing your racket. the faster the ball goes.
A tennis racket is like a extension of your arm. and it is a 3rd category lever. because your shoulder is the pivot point. the arm muscles that you use ( biceps and flexor digitorum ) are the force. and the contact point between the ball and the racket ( most of the clip is the sweet topographic point of the racket because participants will seek to hit the ball on the sweet topographic point be make the best quality shot. ) is the burden. And you can state that it is a 3rd category lever because the force ( musculuss ) are between the burden and the pivot point. Not merely how strong your musculuss are consequence the shootings. besides the racket and racket strings.
There is a broad scope of strings that can impact the quality of the shooting. such as: natural backbones. man-made backbones. nylon. polyester etc. And there are entire 10 sorts of stings. It is largely traveling to present the polyester strings. because it is the most modern and new. and over 60 % of the ATP participant uses it. It have the newest engineering of being the most lasting. ( Henry. D. ( 2009 December 11 ) Polyester Tennis Strings: The Choice of the Pros | Inspired Tennis ) Many participants think that it they are able to use more spin to the ball. and it have be proven that it is true because it have been verified by experiments. ( Wikipedia. ( 14/2 ) . Strings Tennis Retrieved From ) It is besides shown that the fillip spins were because there are less clash between the strings. and the ball stays at contact with the strings longer so that it will hold more clip for the participant to move more spin on it. But it will hold impact the wellness of the participant since it has more clip in contact. it will hold the participant to absorb more quivers and so it will take to a greater opportunity of arm hurt.
There is a truly good illustration: Rafael Nadal. he is truly good known for his extraordinary spin. it is because he have a truly strong arm. and besides because he used a trade name of strings called “Luxilon” . Since he is utilizing this type of strings. he is ever injured and needed to jump a batch of tourneies such as the 2012 London Olympics. Nadal was supposed to be the individual flag carrier for Spain. but he was injured. so he didn’t travel to the Olympic Gamess and had the Pau Gasol as the flag carrier alternatively. ( Reuters. T. ( 2012 ) . Gasol replaces Nadal as Spanish flag carrier | Olympics 2012 ) But the racket ( racket frame ) itself makes a batch of affect on the participant excessively. This new “Luxilon” polyester twine is much more better because the new polyester strings has clip times more spin than the strings on the old wooden rackets. ( Cross. R. ( 2004 ) . The inch that changed tennis everlastingly – Racquet Sports Industry )
Since that the modern. tennis rackets and strings. have a truly high engineerings that can better the quality or the tennis shooting. the cost of the the different equipment/ accoutrements for the tennis rackets are much more expensive than the old wooden rackets. For illustration. the old wooden rackets frame are merely made of wood and doesn’t have any other maps. But on the other side for the modern black lead tennis racket frame. it have used nanotechnology to do the racket be bother lighter and harder and many other good betterments. And so. it will necessitate much more adult male power. clip. machines in order to better the racket utilizing nanotechnology. so it will be much more than merely wooden rackets.
There is besides a broad scope of tennis rackets. and to do the shootings at it’s best qualities and best for the participant. they should happen the 1 that have the maximal weight that the you can utilize. because it the racket will be more steady in contact so the shootings can be more accurate. and the ball you hit can travel faster since the force = mass x acceleration. But if you choose a racket that is excessively heavy. the shootings will still be steady. but you will hold a slower physiological reaction since it is harder to travel it fast. and the velocity will non increase every bit much or possibly lessening because if it is excessively heavy. you wouldn’t have that much acceleration. and the force will still be the same or less.
And most of all if the racket is excessively heavy. you will easy acquire injured. For the old wooden rackets. it is truly light. and made with really scraggy pieces of wood. and it would be truly inaccurate so it will agitate a batch what contacted with the ball and the participant will absorb a batch of quivers and will hold high hazards of arm hurt. Another ground that the new rackets are better is because they have dampener that they can set it between the strings right above the pharynx so that is can absorb most of the quivers before it gets to the pharynx and to the player’s arm.
Sometimes people say that “it is ever the bigger the tennis racket caput size the better. ” because all the old wooden rackets have a truly little racket caput size. It is non a 100 % true. but is is true that the bigger the racket caput is. the bigger the sweet topographic point is. and that means it will hold more opportunity to hit the sweet topographic point where it will hold the best quality of shooting from. But if you hit at the smaller sweet topographic point for the smaller racket caput rackets. the shootings will be more accurate and will be able to travel where you want. when the bigger racket caput one makes it easier to add more spin to it. However. the old wooden racket have a truly little racket size. excessively little. and it is truly difficult to take for the sweet topographic point. ( Cross. R. ( 2004 ) . The inch that changed tennis everlastingly – Racquet Sports Industry )
In decision. the new modern “Graphite Racket” with the new “Luxilon” strings are much better. than the old wooden rackets. because it have a bigger racket caput size for a bigger sweet topographic point. comparatively heavy organic structure to be more steady and more force. and a polyester threading that can do the ball stay contact with the racket longer for more spin but it comes with more quivers that hurts your arm. but it have a quiver moistener to absorb most of the quivers. So the new tennis rackets are more accurate. more faster/force. more spin. and more control/balance/steadiness to do the best tennis shootings.
