Question

Does the work in raising a box on to a platform depend upon how fast it is raise justify your answer

Answer 1

If there is constant velocity then work done remains same . But if acceleration is present then work done will change over a period of time . If variable acc is present then the integration of force as a function of displacement will give you work. Coming back to the point , work does depend upon how fast you do it
