Potential Energy Tutorial

Potential Energy:

Potential energy is the stored energy of position possessed by an object.

Potential Energy Formula :

Potential Energy: PE = m x g x h

Mass:

Acceleration of Gravity:

Height:

where,

PE = Potential Energy, m = Mass of object, g = Acceleration of Gravity, h = Height of object,

Potential Energy Example

Case 1:

A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg, h = 20 m, g = 9.8 m/s²(Gravitational Acceleration of the earth)

Step 1:

Substitute the values in the below potential energy formula: Potential Energy: PE = m x g x h = 6 x 9.8 x 20 Potential Energy: PE = 1176 Joules This example will guide you to calculate the potential energy manually.

Case 2:

On a 3m ledge, a rock is laying at the potential energy of 120 J. What will be the mass of the rock. PE = 120 J, h = 3m, g = 9.8 m/s²(Gravitational Acceleration of the earth)

Step 1:

Substitute the values in the below Velocity formula:

This example will guide you to calculate the mass of the object manually.
