Sounds like you're trying to figure out the theme of " Work" means . Work closely with the energy conversion or transfer. Some form of energy into another form of energy, or some form of energy transfer to another party , they must all go before work or heat transfer can be achieved, for example, when an object in free fall through the gravitational potential energy to kinetic energy work , the fire in the stove to boil water to pass through the transfer of heat in the water leaving the water in the internal energy. The process of completing these tasks, are doing the work or heat transfer "credit" , which is the "power " means. Energy and heat is very similar , so British scientists discovered the relationship between the two Joules , known as the mechanical equivalent of heat: 4.2 = 1 focal energy calories. Note that the power and heat energy just before starting the process of change there is power and "process of the amount of " heat changes the amount of energy , the amount of work to do or how much heat transfer , many of the key points of physical problems using nature of this solution. If the energy does not change, then there is no electricity and heat . In general , say that " a series of objects of power or heat," which is ridiculous because there is no change in the energy process , energy and heat there . Narrowly speaking, the mechanical energy is the power in the accumulation process of repositioning . The promotion is concerned, the work is the measure of all energy conversion , which means "electricity or heat, as if measuring the energy conversion of the ruler of all."
