Answer 1

1. Power is defined as the rate of doing work concerning time or energy utilized per unit of time.
2. $P=\frac{E}{t}$, P=Power, E=Energy, t=time.
3. The S.I unit of power is Watt ($W$).
4. The relation between power, force, and velocity is given by $P=F\times v$ where, F= force and v= velocity.
