Physics formula power. Power can be defined as the rate at which work is done ie. Power is a time-based quantity. Formulas from all the chapters of Class 11 and Class 12 are equally.

The formula for power is. In physics you can calculate power based on force and speed. Denoted by P and measured using the SI unit of power is the watt or one joule per second.

Which is related to how fast a job is done. This formula states that the consumption of energy per unit of time is called power. Y 2 A 2 sinkx t y y 1 y 2 2Acoskxsint x ˆ n 1 2.

This formula is also called the mechanical power equation. Where s is the distance traveled. Because work equals force times distance you can write the equation for power the following way assuming that the force acts along the direction of travel.
