What is Gravitational Potential Energy(GPE)?
Gravitational potential energy is energy that is stored for an object given its position relative to the body. GPE is nothing but the product of object mass and acceleration caused by gravity and the height of the object.
Gravitational Potential Energy = mass * acceleration caused by gravity * height of the object
How to Calculate Gravitational Potential Energy?
Now, here we are explaining how you can calculate GPE(Gravitational Potential Energy) in a step by step process to understand it easily. Let’s see the calculation for the gravitational potential energy.
- Now you need to enter 3 parameters.
- Three parameters are mass, acceleration, and height.
- Now apply the values in the formula.
- Product those three parameters and you will get the answer.
Gravitational Potential Energy Formula
Let’s see the formula for the potential energy of gravitational force,
PEg = m*g*h
PEg is the Potential energy of gravitational force
m is the mass of the object
g is the acceleration due to gravity
h is the height of the object above the earth surface
The gravitational potential energy unit is the joule.
Gravitational Potential Energy Examples
Question : There is a Rollercoaster and the mass of a person is 50 kg inside. The roller coaster is pulled to the top of the hill which has a height of 35m. What is the gravitational potential energy of the person at the top?
m = 50kg, h= 35m, GPE=?
We know that, g = 9.8 m/s2.
Substitute the values,
GPE = 50*9.8*35 = 17150 Joules.
