Best Answer: Energy and work is measured in joules. That is force*distance in N*meters = N*m = W*s. 1000 joules (J) = 1 kJ. Power is measured in watts. That is energy/time = Joules/seconds = J/s Power is the rate at which work is performed or energy is converted. And how do you cost energy?? What does that mean?
