Anything that is moving, energy is transferred to this store when it speeds up and is transferred away from this store when an object slows down.
1 of 11
What does the energy in the kinetic energy depend on?
Mass and speed
2 of 11
What is the kinetic energy formula?
½mv² or 0.5 x mass x speed²
3 of 11
How is energy transferred to the gravitational potential energy store?
When the object is lifted it causes the transfer of energy to the g.p.e. store of the raised object.The higher the object is lifted, the more energy is transferred to this store.
4 of 11
What does the energy in the gravitational potential energy depend on?
The objects mass, height and the strength.
5 of 11
What is the formula of Gravitational potential energy?
mgh or mass x gravitational field strength x height
6 of 11
How does energy transfer from a falling object?
Energy from it's gravitational potential energy store is transferred to its kinetic energy store.
7 of 11
What happens when a falling object has no air resistance?
Energy lost from g.p.e. store = Energy gained from kinetic energy store.
8 of 11
What does air resistance do?
It act against all falling objects and causes some energy to be transferred to other energy stores.
9 of 11
What does stretching and squashing an object transfer energy to?
It's elastic potential energy, so long as the limit of proportionality has not be exceeded.
10 of 11
What is the formula for Elastic potential energy?
0.5 × spring constant × (extension)²
