MCQ

If a force $F $ is applied on a body and it moves with a velocity $v$, the power will be

✓
$F \times v$
B
$F/v$
C
$F/{v^2}$
D
$F \times {v^2}$

✓

Answer

Correct option: A.

$F \times v$

a
(a) Given, Velocity $=v -1 \, force = F$

We know that work done is equal to the product of force and displacement

$W=f \times x$

Divided by t in both sides then we get,

$\frac{w}{t}=\frac{f x}{t} \Rightarrow \frac{x}{t}=v \& \frac{w}{t}=p$

Therefore $p=f\times v$
