to calculate kinetic energy from potential energy

>In a hydro power plant electricity is produced from water. Hydro power plants convert the potential energy of falling water into electricity. Wind Energy Moving air is called wind Wind possesses kinetic energy Wind energy can be used to s..

Study the Following Examples: - Water stored in a reservoir is capable of rotating turbines kept at a lower level. Water stored in a reservoir possesses energy by virtue of its position. A nail hit hard with a hammer gets fixed while if the hammer is just placed on the nail, the nail hard..

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..

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 the body in motion. This type of e..

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..

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 energy of a sy..

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..

Potential Energy of a Spring - Consider a massless spring of natural length 'l', one end of which is fastened to a wall. The other end is attached to a block, which is slowly pulled on a smooth horizontal surface, to extend the spring. If we take the spring as a system, when it ..

. In this case, a positive amount of work has to be done against the attractive force to take the charge from a given location to infinity. Similarly, the potential energy of a system of three charges q 1 , q 2 , q 3 located at r 1 , r 2 , r 3 respectively can be calculated..

Study the following examples - a) Water stored in a reservoir is capable of rotating turbines, which are kept at a lower level i.e, water stored in a reservoir possesses energy. b) If you hit a nail hard with a hammer the nail gets fixed whereas if the hammer is just placed on the nail, t..
