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
A wheel is mounted on a stationary axle starts at rest and is given the following angular acceleration a =(9-12t) (SI units)where t is the time after the wheel begins to rotate.Fin
Given a particle moving along a straight line with fixed acceleration a. Let u be the initial velocity of the particle and v be the velocity at time t. So by definition,
