Potential and Kinetic Energy

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a rolling ball has kinetic energy.

Front

At which point is potential energy greatest?

Back

Potential energy is greatest at the highest point of an object's position.

Front

What kind of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy because it is stored energy that can be released.

Front

What happens to energy when an object falls?

Back

As an object falls, its potential energy is converted into kinetic energy.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transferred or transformed from one form to another.

Front

What is an example of potential energy?

Back

An example of potential energy is a book on a shelf. It has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a car driving down the road.

Front

What happens to the kinetic energy of a ball when it is thrown into the air?

Back

The kinetic energy decreases as the ball rises and converts to potential energy until it reaches its highest point.

Front

What type of energy does a roller coaster have at the top of a hill?

Back

At the top of a hill, a roller coaster has maximum potential energy.
