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.

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.

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has because it has the potential to fall further.
