A hevy box is kept on a smooth inclined plane and is pushed up by a force F acting parallel to the plane. Does the work done by the force F as the box goes from A to B depend on how fast the box was moving at A and B? does the work by the force of gravity depend on this?

Does the work done by a force depend on the frame of reference ?

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

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

Does the work done in moving a body depend on how fast or how slow the body is moved?

Two blocks A and B of mass 2 kg and 4 kg respectively are placed on a smooth inclined plane and 2 kg block is pushed by a force F acting parallel to the plane as shown. If N be the magnitude of contact force applied on B by A, which of the following is/are correct?

A block of mass 2.0 kg is pushed down an inclined plane of inclination 37^0 with a force of 20N acting parallel to the incline. It is found that the block moves on the incline with an acceleration of 10 m/s^2 . If the block started from rest, find the work done by the applied force in the first second .
