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
W=F\( \times \)s
