Kinetic energy and gravitational potential energy

HideShow resource information
What is gravitational potential energy?
The energy an object has because of its position in a gravitational field.
1 of 6
What does lifting an object do?
It does work against the gravitational force (weight).
2 of 6
What happens as a result?
The object gains gravitational potential energy.
3 of 6
What happens when an object falls?
Its GPE is transferred into KE.
4 of 6
What is kinetic energy?
The energy an object has when it is moving. It depends on the mass and speed of the object.
5 of 6
Exam tip:
Don't forget that v^2 means velocity squared, or v x v
