Kinetic Energy 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.

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It has the potential to be converted into kinetic energy.

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy an object has due to its height above the ground. It is calculated using the formula: GPE = mass × gravity × height.

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in objects that can be stretched or compressed, such as springs or rubber bands.

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass. The formula for Kinetic Energy is KE = 1/2 × mass × velocity².

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by four times.

What is the relationship between Kinetic Energy and Potential Energy?

Back

Kinetic Energy and Potential Energy can convert into each other. For example, as an object falls, its Potential Energy decreases while its Kinetic Energy increases.
