Question

To find power we need to determine?

Answer 1

Answer:

Work and time needed to the work

Explanation:

Power is defined as follows:

$P=\frac{W}{t}$

where

P is the power

W is the work done

t is the time needed to do the work

Since the work can also be rewritten as the product between force (F) and displacement (d):

W = F d

The power can be also rewritten as

$W=\frac{Fd}{t}$

But $\frac{d}{t}$ is equal to the velocity, v; so, power can be rewritten as product between force and velocity:

$P=Fv$
