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
Steelyards Either Roman or Danish steelyards can be improvised using short lengths of lead or iron water pipe as counter-weights and loops of wire s pivots. The rod can be o
Do objects of different weights fall with same acceleration on the earth? Yes , objects fall with the similar acceleration regardless of their weights at the surface of earth,
In these diodes electron and hole pairs are formed by junction photoelectric effect. That is the covalent bonds are broken by the EM radiations absorbed by the electron in the V.B.
