what is kinetic energy?

the energy an object has when its moving

New cards

what is kinetic energy dependent on?

the objects mass and velocity

New cards

the greater the mass…

the more kinetic energy an object has

New cards

how do you calculate kinetic energy?

0\.5 x mass x velocity squared

New cards

what is gravitational potential energy?

the energy an object had when it is at a height above the earths surface

New cards

when an object is raised…

its gravitational potential energy increases

New cards

how do you calculate gravitational potential energy?

mass x gravitational field strength x height

New cards

what is the gravitational field strength on earth?

10 N/kg
