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 and speed of the object.

How is Potential Energy calculated?

Back

Potential Energy (PE) is calculated using the formula: 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.
