The energy possessed by a object by virtue of its position or its configuration is called its potential energy.
Concept of potential energy is valid only in conservative field. In conservative force field when a object moves on a round trip then its kinetic energy will not change. But if we assume a point B on the path, then at point B, its kinetic power will not be equivalent as at point A. (Let K.EB < K.EA), we may say that this changes in kinetic energy has stored in configuration of system and this kept energy is known as potential energy of system
Newton's laws of motion (Sir I. Newton) Newton's first law of motion A body remain continues in its state of constant velocity (that may be zero) unless it is acted on
Pascal's principle: Pressure applied onto an enclosed incompressible static fluid is transmitted undiminished to all of the parts of the fluid.
