W = F x Δd


in other words, work equals to force x change in distance.


Therefore, work is done on an object when the force acting on it results in the object undergoing a displacement parallel to the force.





We also know that F=m x a


Force equals mass times acceleration





We sub in for F and find that W = m x a x Δd





We can control the mass of objects when in comes to sports equipments (i.e. make them from light weight materials). when we do that the athlete can do less "work" moving those equipments. He can therefore use less energy to move the equipment and will have lots of energy during the game. Because Work = Energy





In terms of tennis you can see and feel the difference by using the old wooden rackets vs. the new rackets made from lightweight materials such as plastic and carbon fiber. Other than that i don't know much about tennis equipment as i don't play the game myself.





In simple terms, reduce the mass of the equipment, u get less work which means less energy used.
