The si unit of power is watt (w) which is joules per second (j s). sometimes the power of motor vehicles and other machines is given in terms of horsepower (hp), which is approximately equal to 745.7 watts. Power is energy flowing! it is measured as energy per unit of time. no, not that type of power formula! power is the rate of energy per time: p = energy time. example: 3000 j of energy is used in 20 seconds, what is the power? p = 3000 j 20 s = 150 w. we can also change the formula this way:.

Hydropower is energy in moving water people have a long history of using the force of water flowing in streams and rivers to produce mechanical energy. hydropower was one of the first sources of energy used for electricity generation, and until 2019, hydropower was the leading source of total annual u.s. renewable electricity generation. 1. of or relating to political, social, or economic control: a power struggle; a power base. 2. operated with mechanical or electrical energy in place of bodily exertion: a power tool; power car windows. 3. of or relating to the generation or transmission of electricity: power companies; power lines. 4. All machines are typically described by a power rating. the power rating indicates the rate at which that machine can do work upon other objects. 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. Power (physics), meaning "rate of doing work" engine power, the power put out by an engine electric power, a type of energy power (social and political), the ability to influence people or events.
