1
New cards
Work done
The energy required to complete a job
2
New cards
Equation for work done
Work done (J) = force (N) x distance (M); W = f x d
3
New cards
Work done =
Energy transferred
4
New cards
Gravitational potential energy
The amount of energy an object has due to its height above the ground
5
New cards
Equation for gravitational potential energy
Gravitational potential energy (J) = mass (kg) x gravitational field strength (N/kg) x height (m); GPE = m x g x h
6
New cards
Equation for kinetic energy
Kinetic energy (J) = ½ x mass (kg) x speed2 (m/s); KE = ½ x m x v2
7
New cards
Power
The rate of transfer of energy / the rate of doing work
8
New cards
Equation for power
Power = work done / time taken; p = W / t
