Answer 2

What is work?

Work is said to be done when a force is applied on a body and the body moves in the direction of the force.

We can also explain as it is the product of the applied force and the displacement of the body.

The formula of work :-

Work = Force × displacement cos a

Here a is the small angle between Force and displacement.

Some Important Information:-

1. Work is a scalar quantity and the S.I unit is joule.

2. In case the angle between Force and displacement is acute the work will be postive.

3. The dimensional formula for work is ML²T ¯².
