What is the formula for calculating gravitational potential energy?.
- A.Ep = m x g x h
- B.Ep = m x v^2
- C.Ep = 0.5 x k x e^2
- D.Ep = F x s
Model answer
What a good answer should say
- Ep = m x g x h
Explanation
Why this works
The formula for gravitational potential energy (Ep) is Ep = m x g x h, where m is mass, g is gravitational field strength, and h is height. This formula shows how potential energy depends on the height of an object in a gravitational field.
