Potential & 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, an apple sitting on the edge of a table has potential energy because it can fall.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

True or False: Increasing an object's speed will increase its kinetic energy.

Back

True

Front

Which has the greatest Kinetic Energy? A car driving down a hill, a person running down a hill, or a ball rolling down a hill?

Back

A car driving down a hill has the greatest kinetic energy.

Front

Where is Kinetic Energy greatest in a tossed baseball?

Back

The Kinetic Energy is greatest at the point where the baseball is moving the fastest, usually just before it hits the ground.

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 happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

Give an example of an object with high Potential Energy.

Back

A book on a high shelf has high potential energy due to its height.

Front

What type of energy does a moving car have?

Back

A moving car has Kinetic Energy.
