Forms of Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a ball at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

At which point does a ball have the greatest potential energy when rolling down a hill?

Back

While it is at rest at the top of the hill.

Front

What happens to the potential energy of an object as it falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between motion and energy?

Back

Energy is required to change the motion of an object. When an object moves, it has kinetic energy.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating objects, which creates sound waves.

Front

What happens to vibrations when a pitch changes from low to high?

Back

Vibrations are happening faster.

Front

What type of energy does the sun provide for solar power?

Back

The sun provides light and thermal energy that can be harnessed for solar power.

Front

What is a change in motion?

Back

A change in motion occurs when an object moves from one position to another, which can include speeding up, slowing down, or changing direction.

Front

Which of the following is NOT a change in motion?

Back

A car traveling in a straight line.
