what is kinetic energy?
the energy an object has when its moving
2
New cards
what is kinetic energy dependent on?
the objects mass and velocity
3
New cards
the greater the mass…
the more kinetic energy an object has
4
New cards
how do you calculate kinetic energy?
0\.5 x mass x velocity squared
5
New cards
what is gravitational potential energy?
the energy an object had when it is at a height above the earths surface
6
New cards
when an object is raised…
its gravitational potential energy increases
7
New cards
how do you calculate gravitational potential energy?
mass x gravitational field strength x height
