potential energy and energy conservation

Illustration of Conservation of Mechanical Energy - Conversion of gravitational potential energy to kinetic energy: When a body falls from a certain height, its kinetic energy increase..

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 ..

2 due to q 1 . where 'r 1 2 ' is the distance between points 1 and 2. As the electrostatic force is conservative, the work done is stored as potential energy and is given by The potential 'V' would be same, even if the charge q 2 is brought from infin..

Let us study another type of energy, called the potential energy. Potential energy is the energy that can be associated with the configuration (or arrangement) of a system of objects that exert forces on one another. If the configuration ..

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..
