Question

state the formula for calculating work done by a force. are there any condition or limitation in using it directly? is there any mathematical way out for it ?explain

Answer 1

Answer:

work done = force × distance

Explanation:

work done is the product of force applied and the direction moved by the force.

Answer 2

The formula used for calculating the work done is as follows.

Explanation:

The work done by an object is given by the following formula as :

$W=Fd\ cos\theta$

Where

F = force acting on the object

d = displacement

$\theta$ = angle between force and displacement

If force and displacement are in same direction, $\theta=0$. It gives maximum work.

If force and displacement are in opposite direction, $\theta=180$. It gives minimum work.

If force and displacement are in perpendicular to each other, $\theta=90$. It gives no work.
