Question

What is Power? Show that power= Force×Velocity?
Mass 10KG accelerating with 10m/s acquires a velocity of 5m/s​

Answer 1

Answer:

Power is defined as the ability to do work

or in Physics "Work done with respect to time"

As Power(p)= Work(W) / Time(t)

P=W/T and Work = Force x Displacement

So , Power = Force x Displacement/Time

As Displacement/Time = Velocity

So , Power = Force x Velocity

Thanks For Asking

Answer 2

Answer:

power is the rate at which energy transfers. power is the work done in a period of time.

p=w/t (w=f*d)

p=f*d/t (d/t can also be said like v as v=d/t)

so, P=F*V proved

ATQ,

M=10kg

A=10m/s

V=5 m/s

F =M*A

   =  10*5

  f =50 J

so, p=f*v

        = 50*5

      P= 250 WATT
