work vs power vs energy
Power describes the rate of energy transfer. In exercise its the rate of performing muscular work with potential energy.

Power vs Work.
. Power Main Difference The main difference between Work and Power is that Work is the total amount of energy required to move an object from one place by exerting external force. Internal energy is like a fixed deposit and work energy is your savings account that meets routine expenses. Calculating the Amount of Work Done by Forces.
Thus power can be given as the rate of consumption of electrical energy. Energy is the strength needed to perform work while the rate at which work is performed is called power. But you can convert watts into horsepower.
Work is that process in which due to the application of force the energy is transferred in order to cause motion of the object. Power and work are two very important concepts discussed in mechanics. But Joules dont equal watts either--ones a measurement of energy ones a mesurement of power.
The unit of measurement in energy is termed as joules whereas a. Work describes the amount of energy. Definition and Mathematics of Work.
As power deals with the rate of. Lesson 1 - Basic Terminology and Concepts. Power is a measure of how fast energy is being transferred and is measured in units of.
A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. Energy can be stored and measured in many forms. To get energy you multiply power by time.
Refers to an activity involving a force and movement in the directon of the force. As we have discussed recently that doing work generates energy. The work and energy are closely associated terms in physics due to which it sometimes get hard to differentiate between them.
An example of this would be two equal and opposite forces compressing a spring. While if we talk about power it is considered as the amount of. Energy can be defined as the measurement of the ability of something to do work.
Work is a special name we give to Energy that is transferred between objects by the use of Force. The work is the process in which energy transfer takes place. Energy is the capacity to do some physical activities or work such as running jumping etc while power is defined as the rate at which the energy is transferred or the work is completed.
Power is the rate of energy consumed in a unit of time Power Work time. You do not touch fixed deposits as long as there is money in the. 1 Watt 1 Joule 1 sec.
The momentum from one force is canceled out by the other but both forces have a positive. For kWh it is kWh energy kW powertime usually hours. Work is determined by factors like force and displacement on.
The energy that the object consumes on average working per unit time is average power. Work is the energy required to move an object whereas power is meant as the energy spent to move the object. To get power you divide instead of multiply.
Here in the context of work and energy power is simply the rate of doing work. It is not a material substance.
