Potential and Kinetic Energy Review

Front

A bicycle rider is traveling up a hill. When the rider reaches the top of the hill, she stops to rest. Then she travels down the hill. Which statement correctly describes the potential energy and the kinetic energy of the bicycle rider?

Back

When the rider is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.

Front

Conservation of energy means that

Back

energy can be neither created nor destroyed

Front

Kinetic energy can be described as

Which is the best example of an object with only potential energy?

• water being poured out of a pitcher
• a ball being thrown across a field
• a boulder resting on top of a cliff
• a boat sailing through the water

Back

a boulder resting on top of a cliff

Front

As a boulder rolls from the top of a hill to the bottom, how does its potential and kinetic energy change?

Back

Potential energy decreases and kinetic energy increases.
