Question 129

A child slides down a playground slide. At the bottom of the slide, the child has less kinetic energy than the gravitational potential energy they had at the top.

What happens to the 'lost' energy?

A

It is destroyed by the frictional force acting on the child.

B

It is converted into internal (thermal) energy and sound.

C

It is stored as chemical energy within the slide.

D

It is destroyed when the child reaches the bottom of the slide.
