Question

Prove that p= F.V where f is force and v os the velocity of body

Answer 1

Correct Question

Prove that P = F × V where F is Force and V is the velocity of the body

Solution

Power is the rate of doing work in a given time

To prove the relationship P = F × V

We Know That,

$\sf P = \dfrac{W}{T}$

But $\sf{ W = F \times s}$

Now,

$\longrightarrow \sf P = \dfrac{Fs}{t} \\ \\ \longrightarrow \sf P = F \times \dfrac{s}{t}$

$\sf{Here}\begin{cases}\sf{W \longrightarrow Work \ Done}\\\sf{V \longrightarrow} Velocity \\ \sf{F \longrightarrow Force} \\ \sf{P \longrightarrow Power}\end{cases}$

$\huge{\longrightarrow \ \boxed{\boxed{\sf P = FV}}}$
