# Physics - Kinetic Energy

HideShow resource information
What is power?
The measure of how quickly work is being done and so how quickly energy is being transfered.
1 of 7
What is gravitation potential energy?
The amount of potential (stored) energy in an object above the earths surface. This depends on mass and height above ground.
2 of 7
What does kinetic energy depend on?
Mass and speed.
3 of 7
On a pendulam, when the bob is at it's highest point, what is at it's maximum?
It's gravitational potential energy.
4 of 7
At the bottom of the swing, what is at it's maximum?
It's kinetic energy.
5 of 7
What is momentum?
The tendency of an object to keep moving in the same direction.
6 of 7
What else does momentum depend on apart from mass and speed?
Velocity (speed in a particular direction).
