Step-by-step explanation:

The power of an object is defined as the work done divided by total time taken. Its SI unit is watts. It is denoted by W. Its expression is given by :


P=(W)/(t)

Since, W = F.d


P=(F* d)/(t)

Since,
(d)/(t)=v


P=F* v

It is also defined as the product of force and velocity. So, to find the power of an object it is required to know that force and the time taken.
