### Understanding Work and Energy.

Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force. Work done = force × distance = F × s, 1 Joule = 1 Newton × 1 metre. The unit of work is joule. The energy of a body is its capacity of doing work. The S. I. unit of energy is Joule (1 KJ = 1000 J). Form of energy: (P.E & K.E.), heat energy, light energy, sound energy etc. Kinetic energy is the energy possessed by a moving body by virtue of its motion.
