the law of conservation and energy

First Law of Thermodynamics or Law of Conservation of Energy - 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..

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..

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 the Uni..

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

If the north pole of the magnet is moved towards the coil, the upper face(U.F) of the magnet acquires the north polarity on closing the key between 2 and ..

Conservation of Mechanical Energy - 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 ..
