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
Truck and The Ball Suppose a pickup truck moving along with a constant speed along a city street. Within the course of its motion, a ball is projected straight upwards through
Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity
Elastic Collision Collisions among objects are governed through laws of momentum and energy. While a collision occurs in an isolated system, the whole momentum of the system of
