Question

The expression for power of an object is equal to

Answer 1

Answer:

power = work done/ time

Answer 2

Answer:

Rate of doing work is known as Power.We can say that one unit of energy must be used to do one unit of work.

We know that,

$Power = \frac{Work}{Time}$

Again we know,

$Work= F.S$

So,

$Power = \frac{F.S}{t} = F.V$

Because,

$\frac{S}{t} = v$

Here F is the force,

S is displacement

t is time taken
