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 the speed at which it is moving.

In which position does a spring lose its Elastic Potential Energy?

Back

A spring loses its Elastic Potential Energy when it returns to its natural length (position X).

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object has due to its height above the ground, calculated as mass x gravity x height.
