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

Explanation

1. As we know the gravitational force is conservative force in nature.
2. Conservative force are those force which depends only on the final and initial position of the object.
3. Here the work done will depend only on the final and the initial position of the box, not on time taken to raise it up or how fast it is raised up

Hence, 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
