Heartwarming What Is Power In Physics
POWER Power is the rate of work done in a unit of time.
What is power in physics. We explore the multiple ways we can express power mathematically by working through an exam. In physics however it has a very specific meaning. Most people have heard about the co.
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. The SI unit of power is Watt W which is joules per second Js. 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.
The equation that describes power is. In physics you can calculate power based on force and speed. Power is the time rate of doing work of an agent and it is measured by work done in unit time.
Where s is the distance traveled. Power is a scalar quantity. Because work is energy transfer power is also the rate at which energy is expended.
They think that more power full machine does more work. In physics power represented by the symbol P is a certain amount of work done in some way in a given unit of time. If the magnitude of the force F is measured in pounds and the speed ν in feet per minute the power equals Fν foot-pounds per minute.
In the International System of Units the unit of power is the watt equal to one joule per second. That is it is the amount of work per unit of time that an object or system produces. Power is a scalar quantity.
