After you have studied lesson, you must be looking for notes to memorize. Work: When a force acts on an object and the object shows displacement, the force has done work on the object. Energy The capacity of a body to do work is called the energy of the body. Forms of Energy: The various forms of energy are potential energy, kinetic energy, heat energy, chemical energy, electrical energy and light energy. Kinetic Energy: Energy possessed by a body due to its motion. Kinetic energy of an object increases with its speed. Derivation Let an object of mass m, move with uniform velocity u, let us displace it by s, due to constant force F, acting on it Potential Energy The energy possessed by a body due to its position or shape is called its potential energy.
