Question

Problem 15b

Answer 1

Given information

Given that a tennis ball is served and asked to explain the energy transformations taking place in the process.

Step-by-step explanation

Step 1.

Energy is the ability to perform work. Energy can neither be created nor destroyed, but it can be transformed from one form to another.

 

In a game of tennis, when the tennis player throws the ball upward then the work done by the tennis player on the tennis ball is positive and this work is stored as kinetic energy of the ball. When the ball reaches the highest point, the stored kinetic energy is transformed completely into potential energy.
