Electric power, a physical term, is called electric power. It is a physical quantity used to express the speed of electric energy consumption, expressed by P, its unit is Watt, abbreviated as "Watt", and the symbol is W, that is, power is a physical quantity that describes the speed of doing work. Power includes electric power and mechanical power.
The workload is fixed, and the shorter the time, the greater the power value. The formula for finding power is power = work/time. Power is a physical quantity representing working speed. The work done per unit time is called power, which is expressed by P. Therefore, power is equal to the scalar product of the acting force and the speed of the force point of the object.
Physics refers to:
Physics is a subject that studies the most common laws of motion and the basic structure of matter. Physics, as the leading discipline of natural science, studies the most basic motion forms and laws of all substances from the universe to elementary particles, so it has become the research basis of other natural science disciplines.
Physics began in the era of Galileo and Newton, and now it has become a basic science with many branches. Physics is an experimental science, and it is also a science that advocates rationality and attaches importance to logical reasoning. Physics, which makes full use of mathematics as its working language, is the most accurate natural science subject today.
