Question

Does the work done in raising a box on to a platform depends upon how fast it is raised up? If not, why?

Answer 1

Answer:

Explanation:

No, because work is only depend on force and displacement,, or this will be calculated by , w = FScos(A) where A is angle between direction of force and direction of displacement.

Answer 2

Work done does not depend upon how fast an object is raised up.

Explanation:

The work done by an object is given in terms of force and its displacement. Its formula is given by :

$W=Fd\cos\theta$

F is force

d is displacement

$\theta$ is the angle between force and displacement

It is clear that work done depends on force, distance and angle between force and displacement. We can say that the work done in raising a box on to a platform does not depends upon how fast it is raised up.
