Gravitational Potential Energy (GPE)

Question 1

What is Gravitational Potential Energy?

Answer 1

Gravitational Potential Energy is the potential energy stored when at object is moved at height above the surface of the ground.

Question 2

How does moving an object affect its GPE?

Answer 2

When an object is moved at height and then placed somewhere at height (like a shelf) the energy used to move that object is transformed into GPE.

Question 3

What is the Equation for calculating GPE?

Answer 3

Ep = M x G x H

where Ep is Energy Potential
M is mass in Kilograms
G is gravitation field strength in N/kg (N=newton)
H is height in metres.
