Question

Does the work done in raising a box onto a platform depend on how fast it is raised?

Answer 1

1. It is defined as the product of force and displacement.
2. Work is said to be done when we apply force on the object and there is displacement in the object in the direction of applied force.
3. Work $=force\times displacement.$
4. Work done depends only on displacement and the force acting in the direction of displacement, not on the velocity of the object or time for which the force act on the body.

The work done in raising a box onto a platform does not depend on how fast it is raised.
