Question

The formulas for power and work are and , where P is the power, W is the work done, t is the time, F is the force, and d is the displacement. Which formula represents the relationship between displacement and power?

Answer 1

Power= work/time, work/time=(force x displacement)/time

therefore, power= (Fd)/t

Answer 2

`P = (Fd)/(t)`

Explanation:

Thinking process:

The concept of power is expressed as the work done per unit time.

Thus, power is given by:

Power =
`(work)/(time)`

However, the work done by a force is given by:

work done = force × distance in the direction of the force

Thus, power is work per unit time given by:

`P = (Fd)/(t)`
