gravitational energy

It is the energy stored in objects that are at a height above ground.

Front

At which point does the cart have the highest gravitational potential energy?

Back

Position (a) because that is the highest point.

Front

At which point does the cart have the lowest gravitational potential energy?

Back

Position (c) because that is the lowest point along the track.

Front

What type of energy is found in moving objects?

Back

Kinetic energy

It is the energy that a moving object has.

The greater the speed, the higher the kinetic energy.

Front

What is light energy?

Back

Light energy is the energy that allows us to see.
