WORK, ENERGY AND POWER

Abstract

Work is defined as a force acting upon an object to cause a displacement. Work is defined as a force acting upon an object to cause a displacement. Amount of work done depends on the force and displacement. The greater the distance, or force, the greater the work done. Energy is often defined as the ability or capacity to do work. The energy transferred to an object by the work of moving it a distance of one meter against a force of one newton. The common energy are kinetic energy and potential energy. Kinetic energy is also called as the energy of motion. The faster an object moves, the more kinetic energy it has. Conservation of energy states that energy is neither created nor destroyed, it is converted from one form to another. This principle implies that the total amount of energy in a closed system remains constant. Power is the rate at which work is done or rate of energy transformed. It is simply energy exchanged per unit time, or how fast you get work done.
