If power is increased by 50 % and work done is constant, then the time taken is reduced by:
Same amount of force 10 N is acting on two bodies in two different ways. Case 1: Force is acting in the direction of displacement of the body. Case 2: Force is making an angle of 60° with the direction of displacement. If the displacement is 'd' meters in both the cases, then what is the relation between the work done in both the cases?
A force of 12 N is acting on a body and the same force 12 N is acting on the same body but in a different direction. If the body moves with a displacement of ′d′ metres, then what is the work done?
If the unit of displacement and force be increased four times, then the unit of work done is
