the conservation of energy

Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to anothe..

It is a common experience that energy cannot be generated without consuming energy of some other kind. If a certain amount of one kind of energy is produced, an equal amount of some other kind of energy disappears so that the total energy of t..

Law of Conservation of Energy - Let us see what is actually taking place in the following examples: Steam engine- Here the coal burns and the heat due to the combustion of coal converts water into steam and the expansive force exerted by the steam on the piston of the engine mov..

The total energy in the universe is present either as kinetic energy or as potential energy. For example, the water stored in a dam possesses potential energy by virtue of its height (position). When this water is allowed to fall, its potential ene..

We can see many situations in which energy is transferred to or from objects and systems, similar to money being transferred between accounts. In each situation, we assume that the energy that was involved can be accounted for, that is, energy cannot appear or di..
