Potential Energy Tutorial



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.



This tutorial will help you dynamically to find the Potential Energy problems.
