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 Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object has due to its height above the ground. It is calculated as weight times height.

How does height affect Potential Energy?

Back

The higher an object is, the more gravitational potential energy it has, because it has the potential to fall.

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

In which position does a pendulum have maximum potential energy?

Back

A pendulum has maximum potential energy at its highest points (the ends of its swing).

What happens to Potential Energy as an object falls?

Back

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

What is the formula for calculating Gravitational Potential Energy?

Back

The formula for Gravitational Potential Energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
