Question

6. Define power and show that P = F. ū.
​

Answer 1

Explanation:

we have to show that P = F.V

Power is the amount of energy required for specific time. in simple way, power is the ratio of amount of energy to time taken. if P is power , E is energy and t is time. then, P = E/t. Energy = workdone = force × displacement.

Answer 2

Answer:

power is the measure of rate at which work is being done.

Explanation:

so

• P=dW/dT. As here d represents change

As we know

W=F.d

then

P=F.d/T

• d/t is the velocity
• then here is ur result

P=F.V
