Question

define power ,it's si unite ,how it is recorded to velocity
​

Answer 1

Answer:

In calculus terms, power is the derivative of work with respect to time. If work is done faster,power is higher. If work is done slower, power is smaller. Since work is force times displacement(W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v.

Answer 2

Answer:

rate of doing electric work is called power.

watt is the si unit
