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.
kWh, Energy. The watt-hour (symbol WÂ·h) is a unit of energy. It is commonly used in the form of the kilowatt-hour, which is 1,000 watt-hours. It is not an SI unit because it contains the non-SI unit hour. The SI unit of energy is the joule (J), equal to one watt-second.
