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.
In science, electrical energy is measured in joules. However, another unit of electrical energy, the kilowatt. hour (kW. h), is the amount of energy that is used by a load of exactly one kilowatt running for exactly one hour.he kilowatt.hour (kW.h). It is the amount of energy that is used by a load of exactly one kilowatt running for exactly one hour. The kW.h unit is used to measure the tota â¦ l amount of energy used in a building (a home, an office, a factory, etc.) over a particular period of time, usually one month or three months.
