kinetic energy

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 moves the loc..

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 for, that ..

Work Energy Theorem - According to this principle, work done by a force in displacing a body, gives the measure of the change in kinetic energy of the body. When a force does some work on a body, the kinetic energy of the body increases by the same ..

For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called the threshold energy. This implies that ther..

Internal Energy - Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or in..

The electric potential energy of the alpha particle at the distance of closest approach from the nucleus was found to be equal to Potential energy x charge on a partic..

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 potentia..
