the kinetic energy of a substance is the kinetic energy of its particles

A dancing or running man is said to be more energetic than a sleeping man. In physics, a moving particle is said to have a more energy than an identical particle at rest. Quantitatively, the energy of the moving particle is given by The kinetic..

Kinetic Energy - It is a matter of common experience that a fast moving stone can break a windowpane, falling water can rotate turbines and moving air can rotate windmills and propel sailboats. In all these examples, the moving body possesses energy. Work is done by th..

Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numb..

Momentum and Kinetic Energy - We know that all moving objects possess momentum. Momentum of the body is defined as the product of its mass and the velocity. Now let us see how kinetic energy of a body is related to its momentum. Consider a body of mass 'm' mo..

Translational Kinetic Energy of Gas - The total translational energy of all the molecules of the gas is the average kinetic energy of a molecule is from equation (v..

Average kinetic energy of a molecule is The total kinetic energy of all the molecules is The average speed is somewhat smaller than the rms speed. It can be shown th..

Kinetic Energy and Temperature - Let us consider one-gram molecule (mole) of the gas. Let M and V be its mass and volume respectively. The pressure exerted by the gas is given by: But PV = RT where T is the absolute temperature of the gas and R is the molar gas constant. R is th..
