Q
Kinetic energy
A
Kinetic energy = 1/2 X mass X speed^2
2
Q
GPE
A
GPE = mass X gravitational field strength X height
3
Q
Power
A
Power = work done / time taken
4
Q
Efficiency
A
Efficiency = useful energy output / total energy input
5
Q
Density
A
Density = mass / volume
6
Q
Acceleration
A
Acceleration = change of velocity ÷ time taken
