An exponent
For example the power in is the 2. It is how many times the 5 is multiplying itself. In this case 5 would multiply itself 2 times.
So... not 5 x 2, but 5 x 5
It is the rate of doing work
<h2>Explanation</h2>Power can be defined as the ability to influence the behavior of others and resist unwanted influence in return.
In physics, power is rate of doing work, or it’s the amount of energy transferred per unit time. Power is a scalar quantity mean a specific direction is not required for it.
Being the rate of work, the equation for power can be written:
For example
You are running upstair, you are applying force to cover some distance in specific time
The power developed is 500 W ( to the nearest Watt)
Power(P) is the rate at which work is done. Work done (W) is the product of the force applied on the object and the displacement (s) made by the point of application of the force.
Therefore,
Substitute the given values of force , displacement and time
Thus the Power can be rounded off to the nearest value of 500 W
