Sometimes people are mean because they are not like you and they want to be like you. Although it's always good to try to find out why exactly someone is being mean to you, you often may never know; however, you may have a gut feeling if someone's being mean to you and you don't have to stand for it.
Thus, in SI units, a force of 1 N exerted over a distance of 1 m is 1 NÂ·m of work. The Work-Energy Theorem states that the work done on a body is equal to the change in energy of the body. 1 NÂ·m = 1 J (joule), the SI unit of energy.
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?
