potential energy = mass x acceleration x height 

             (J)                (kg)       (ms-2 )            (m)

1 of 5

kinetic energy = 1/2 x mass x velocity2

                    (J)                         (kg)      (ms-1)


2 of 5

work done = energy transferred 

power = work done / time taken

(w)             (J)               (S)

3 of 5

cost = power x time x cost per unit 

4 of 5

efficiency = useful energy output / total energy input x 100%
