Consider the following information:
When a force acts on an object to cause a displacement (d) of the object, it is said that work (W) was done on the object.
Power is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation:
Power (P) = work (W) / time (t)
→ P = [ force (F) x displacement (dx) ] / t
→ P = F x velocity (v)
→ P = Fv
When a force acts on an object to cause a displacement (d) of the object, it is said that work (W) was done on the object.Explanation
Randy and Aaron do the same amount of work. They apply the same force to lift the same barbell the same distance above their heads. Aaron delivers more power since he does the same work in less time. Power and time are inversely proportional.
