Question

Prove that, Power (P) = F.v in vector​

Answer 1

Answer:

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

$P = \frac{f \: s \cos( \alpha ) }{t}$

$P = {fv \cos( \alpha ) }$

$v = \frac{distance \: (s)}{time \: (t)}$ A constant force moves an object at constant velocity, the power is just P = f•v.

Alternative,

$P = \frac{dW}{dt}$

$P = \frac{dF•S}{dt}$

$P = F•v$
