Question
The following statements appeared in Tennis Trade magazine:The racquet is an instrument of work and transmitter of energy. The amount of energy you
transfer to the ball can be best be defined as a Force (F). The amount of this Force can then be
equated to its mass times its acceleration: F=ma
F = Force is the amount of energy you transfer to the ball by the racquet.
m = Mass is the weight of the racquet divided by gravity, or m=w/g, gravity is generally 32
ft/sec and for all practical purposes, simply refer to it as weight.
a = Acceleration is the speed with which you swing the racquet.
From the above equation (F=ma), you can see that the faster one swings the racquet the greater
the force will be transmitted to the ball.
Which of these statements are false? (If a statement makes no sense, regard it as false.)
Would any of these statements help you to become a better tennis player?
Explanation / Answer
Firstly, The amount of energy you transfer to the ball can be best be defined as a impulse but not force as it the transmission occurs for a very short interval of time. F = Force is the amount of energy you transfer to the ball by the racquet. (false)(force is rate of change of momentum but not energy) a = Acceleration is the speed with which you swing the racquet. (false)(because acceleration is rate of change of velocity but not velocity itself.) The statements given will help u a little in becoming a better tennis player.
