Beautiful Work Physics Formula For Power
This formula states that the consumption of energy per unit of time is called power.
Physics formula for power. This is the most common and basic formula of power which we come to know about very early. Examples For Power. Electric Power In physics an electric power measure of the rate of electrical energy transfer by an electric circuit per unit time.
The physics formulas for class 11 PDF is provided here so that students can understand the subject more effectively. In the International System of Units SI the unit of power is the watt W which is equal to one joule per second. X cm P Px i m i m i.
SAT Subject Physics Formula Reference Dynamics continued p Ft p change in momentum F appliedforce t elapsedtime Ft is called the impulse. Thus a Watt is equivalent to a Joulesecond. Because work is energy transfer power is also the rate at which energy is expended.
Here E stands for energy in joule and t stands for time in seconds. We can define average power as the total energy consumed divided by the total time taken. M 1 m 2 C r m2r m1m2 m1r m1m2 2.
How much power does it use. Power is a time-based quantity. Other common and traditional measures are horsepower hp comparing to the power of a horse.
The formula for power is given below. The standard unit of measurement of power in Watts and kilowatts denoted as W and kW respectively. The dimension of power is energy divided by time.
