What is power explain?
Power is the rate of doing work or the rate of transfer of energy.
If W is the amount of work done in time t, then power is given by the expression, Power = Work/Time = Energy/Time.
P = ( W)/T.
It is expressed in watt (W)..
What is power in physics and examples?
As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second. … Thus, the power of a machine is the work/time ratio for that particular machine. A car engine is an example of a machine that is given a power rating.

How is power calculated?
Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power.
Why is power so important?
Power is the capacity to cause change, produce effects on others or potentially influence others (PSU WC, L. … 7.). Power is the function of a relationship because it belongs not only to the leader, but also to the followers and the situation.

Power Formula 2 – Mechanical power equation: Power P = E ⁄ t where power P is in watts, Power P = work / time (W ⁄ t). Energy E is in joules, and time t is in seconds.
What is work and power?
083 – Work and Power In this video Paul Andersen explains how the work is a product of the external force applied to an object or system and the distance it moves. Power is a measure of the amount of work done per unit time. The work can be calculated as the area under a curve in a Force-Distance curve.
