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 girl pulling a wagon down the street is an example of Kinetic Energy.

Front

Give an example of Potential Energy.

Back

A car that is stopped at a traffic light has Potential Energy.

Front

What happens to Potential Energy when an object falls?

Back

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

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 the formula for Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has due to its position above the ground.

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 high Potential Energy.

Front

What type of energy does a roller coaster have while going down the tracks?

Back

While going down the tracks, a roller coaster has Kinetic Energy.
