Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential Energy is stored energy that has the potential to do work. It is energy based on an object's position or state.

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

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases, assuming no energy is lost to air resistance.

Front

Where is Potential Energy highest on a roller coaster?

Back

Potential Energy is highest at the top of a big hill on a roller coaster.

Front

What is an example of Kinetic Energy?

Back

An example of Kinetic Energy is a roller coaster speeding down a hill.

Front

What type of energy is present in a stretched rubber band?

Back

A stretched rubber band has Potential Energy due to its position.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass; if the mass of an object doubles, its Kinetic Energy also doubles if velocity remains constant.

Front

How does height affect Potential Energy?

Back

Potential Energy increases with height; the higher an object is, the more Potential Energy it has.
