Gravitational Potential Energy | GCSE Physics Questions
GPE is the energy stored in an object due to its position in a gravitational field.
Do you know why g is 9.8 N/kg on Earth?
What is Gravitational Potential Energy | Questions?
"Energy stored in an object due to its height in a gravitational field."
What is the gravitational field strength on Earth (approx)?
A 5 kg weight is lifted 2 metres. Calculate its GPE (g = 9.8).
Which height change results in the largest GPE increase for the same mass?
GPE Key Facts
GPE = mass x gravitational field strength x height (Ep = mgh).
The higher an object is, the more GPE it has.
Energy is transferred to GPE when work is done lifting an object.
Exam Tip: Make sure height is in metres (m). If given in cm, divide by 100 first!
