Potential and Kinetic 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 rock 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. For example, a moving car or a rolling ball has kinetic energy.

Front

How can you identify Kinetic Energy in an object?

Back

You can identify Kinetic Energy in an object by observing if it is in motion. If an object is moving, it has kinetic energy.

Front

What is the relationship between Potential and Kinetic Energy?

Back

Potential Energy can be converted into Kinetic Energy. For example, when a roller coaster descends from a height, its potential energy converts to kinetic energy as it speeds up.

Front

Give an example of an object with Potential Energy.

Back

A book on a shelf has potential energy because it has the potential to fall due to gravity.

Front

What happens to Kinetic Energy when an object speeds up?

Back

When an object speeds up, its Kinetic Energy increases. Kinetic Energy is directly proportional to the square of the speed.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for calculating Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is an example of an object that has both Potential and Kinetic Energy?

Back

A swinging pendulum has both potential energy at its highest point and kinetic energy at its lowest point.

Front

What type of energy does a skateboard have when it is moving?

Back

A moving skateboard has Kinetic Energy.

Front

What type of energy does a rock at the edge of a cliff have?

Back

A rock at the edge of a cliff has Potential Energy.
