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/s^{2}(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/s^{2}(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.
