1 answer:

8 0

The statement about the skateboarder's energy which is true is: B. As he travels from the bottom of the pipe to the top, KE turns into PE.

<h3>What is potential energy?</h3>

Potential energy refers to a form of energy possessed by a person due to its height (position or location) above planet Earth.

<h3>What is kinetic energy?</h3>

Kinetic energy can be defined as a form of energy that is possessed by a person due to its motion or change in velocity (acceleration).

<h3>The steps involved in the conversion of energy.</h3>

In order to convert kinetic energy (KE) to potential energy (PE), an object or physical body must be made to remain static at a height. Thus, as the skateboarder travels from the bottom of the pipe to the top, kinetic energy (KE) turns into potential energy (PE) and his PE is greatest at the top of the ramp.
