Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object that is in motion. It depends on the mass and speed of the object.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state. It can be converted into kinetic energy.

Front

Give an example of Kinetic Energy.

Back

A roller coaster gliding down the tracks is an example of Kinetic Energy.

Front

Give an example of Potential Energy.

Back

A cup sitting on the edge of a table is an example of Potential Energy.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its speed.

Front

What is the formula for Kinetic Energy?

Back

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

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy held by an object because of its height above the ground.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has due to the gravitational force acting on it.

Front

What is an example of an object with high Potential Energy?

Back

A car that is stopped at a traffic light has Potential Energy because it can move when the light turns green.
