gravitational potential energy Flashcards
1
Q
what is energy in the GPE store of an object?
A
the energy an object has due to its height in a gravitational field
2
Q
what happens when an object rises?
A
energy is transferred to its GPE
3
Q
what happens when an object falls?
A
energy is transferred away from its GPE store
4
Q
formula for GPE?
A
mass x gravitational field strength x height
5
