Work done = force × distance in direction of force (W = Fd, unit: J)Kinetic energy = ½mv²Gravitational PE = mghPower = work done ÷ time = energy transferred ÷ time (P = W/t, unit: W)Efficiency = useful energy output ÷ total energy input (× 100 for %)Electrical energy = power × time (E = Pt)33 Cambridge IGCSE 0654 questions on work & power, across all three components.
