Definition Work Power Energy Physics
Power is the time rate at which work is done.
Definition work power energy physics. Work is the result of a force acting over a certain distance. In the international system of units the unit of power is the watt equal to one joule per second. Learn what power means and how we use it to describe the rate of energy transfer. In physics as well energy is related to work similarly but as already mentioned the definition of the word work is very precise itself in physics hence the definition of energy as well.
The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Concepts of work kinetic energy and potential energy are discussed. These concepts are combined with the work energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state. Work is done when a force is exerted on an object and the object moves from one place to another.
In physics power is the amount of energy transferred or converted per unit time. What is electric power. It is higher when work is done faster lower when it s slower. We describe this in terms of power.
Work and energy can be considered as two sides of the same coin. We often come across the word power as well for example the bodybuilder hit the punching bag with huge power so in a very crude way we could say that the. Like work and energy power is a scalar quantity. Work energy and power.
In ordinary conversation the word power is often synonymous with energy or force in physics we use a much more precise definition. Electric power definition it is the rate at which work is done or energy is transformed in an electrical circuit simply put it is a measure of how much energy is used in a span of time. Home high school ap physics notes work energy and power. In physics the rate of transfer of electrical energy by an electrical circuit per unit time is called electrical power.
Work energy and power are the most used terms in physics. In older works power is sometimes called activity. Work work has a specific definition in physics. In physics power is the rate in which work is done or energy is transferred over time.
Science physics library work and energy work and energy what is power. This distance is called the displacement of.
