WORK AND ENERGY

Whenever a force makes a body move , then work is said to be done or work is done when force produces motion. And for doing work energy is required.

Work done by a force on a body depends on the two factors :

(i) Magnitude of the force.

(ii) Distance through which the body moves.

Now , we can define work as following : Work done in moving a body is equal to the product of force exerted on the body and the distance moved by the body in the direction of force. i.e.

WORK=Force​\( \times \)​Distance

or 

W=F​\( \times \)​s
