Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object because of its position or state. For example, a ball at the top of a hill has potential energy.

Front

Give an example of Kinetic Energy.

Back

A soccer player running around the soccer field is an example of kinetic energy.

Front

Give an example of Potential Energy.

Back

A roller coaster at the top of a hill has potential energy because it is about to go down.

Front

What happens to Potential Energy when an object falls?

Back

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

Front

What is the relationship between Kinetic Energy and speed?

Back

Kinetic energy increases with the square of the speed. If you double the speed, the kinetic energy increases by four times.

Front

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

Back

A baseball thrown in the air has kinetic energy while moving and potential energy at its highest point.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has due to its position.

Front

What is the formula for Kinetic Energy?

Back

The formula for kinetic energy 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 is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
