Q
Relationship between efficiency, useful energy output and total energy output
A
Efficiency = useful energy output ➗ total energy output x 100%
2
Q
Work done = force x distance moved
A
W = F x d
3
Q

A
GPE = m x g x h
4
Q
Kinetic energy = 1/2 x mass x speed2
A
KE = 1/2 x m x v2
5
Q
Power = work done ➗ time taken
A
P = W➗ t
