work vs power vs energy
W is the symbol which denotes energy. Work and energy are the two sides of a coin as both are interconnected to each other.

Then work done will be.
. Work Energy and Power are fundamental concepts of Physics. In physics energy is the ability to do work or the work done while power is rate of energy output. If you do 100 joules of work in one second using 100 joules of energy the power is 100 watts.
The unit used to measure energy is joules or watt-seconds. If the object does any work the value of the power cannot be zero. Work is the amount of energy transferred when an object is moved by an unbalanced external force acting on it.
Work is the displacement of an object when a force push or pull is applied to it. A fine line of difference exists in the way we use the word work in our routine activities and in science. Representation by letter Electrical energy is denoted by the W or E.
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 and its SI unit is Joule whereas Power is the rate of doing work and its SI unit is Watt. No movement no work same force bigger distance more work etc Power is work divided by time. This article discusses work energy and power in detail.
So if I push a boulder up a hill I expend the same amount of energy regardless of how long it takes me. Imagine moving a table or seat from your living room to your dining room. Work is force times distance.
The unit used to measure this is watt or joules per second. A newton is the amount of force it takes to accelerate a one-kilogram 1 kg object at an acceleration of 1. It is power which is integrated over time.
You must have energy to accomplish work - it is like the currency for performing work. Electrical power is denoted by the P. In the example above if you push the object slowly you are exerting a small amount of power but it will take a bit longer.
We provide top electrical services that best fit your buildings needs and present energy management solutions. For kW it is kWpower kWhenergy time. Lesson 2 - The Work-Energy Relationship.
We define the capacity to do the work as energy. P is the average power output measured in watts W ΔEsys is the net change in energy of the system in joules J - also known as work. The two measurements are connected through math.
The work is the process in which energy transfer takes place and the objects travel in the direction of the force applied. The unit of measurement in energy is termed as joules whereas a watt is the measurement unit of power. On the other hand power is the rate at which the energy is spent.
For kWh it is kWhenergy kWpowertime usually hours. MATH But I promise this math is easy to understand To get energy you multiply power by time. Answer 1 of 38.
As Seattles premier electric company Kirby Electric specializes in commercial and industrial contracting. Is the capacity for doing work. Calculating the Amount of Work Done by Forces.
These include kinetic potential thermal gravitational electromagnetic sound light and elastic. In the International System of Units SI force is measured in newtons N. Lesson 1 - Basic Terminology and Concepts.
Work is measured in joules whereas power is measured in watts. Power is the rate of energy consumed in a unit of time Power Work time. It exists in various forms like.
Since V IR E I2R. This is easier to understand if you realize that Work Force x Distance. You divide the energy by time.
Same work done in a shorter time higher power Energy is the capacity to do work. It is a scalar quantity. The symbol used to.
To get power you divide instead of multiply. Power is defined as the rate at which a specific work is done or which the energy is transmitted. W VQ We know I Qt So we can write Q I t Thus on substituting the value of Q we get W VI.
Energy is defined as the capacity to do some work. Power is the work done per unit of time. Δ t is the duration - how long the energy use takes - measured in seconds s Multiplying a value of power and the period of time over which it is used gives an amount of energy.
To do 100 joules of work you must expend 100 joules of energy. Work represents the amount of energy transferred when doing something. Comparison Chart ADVERTISEMENT CONTINUE READING BELOW What is Work.
However doing it in a shorter time period requires more power. On the other hand energy is the ability of the body through which one can do the work. Work is referred to as the displacement of an object when a force push or pull is applied to it while energy is referred to as the capacity to do the work.
Power represents how fast the energy was transferred. Work Energy and Power are the most important terms used in Physics that the students learn in school early on. Moreover the energy can neither be created nor be destroyed.
In an electrical and electronic circuit electrical energy is defined as the capacity to do electric work. I know youre probably not concerned with this technical distinction. Is the rate of doing work or the rate of using energy which are numerically the same.
In physics energy is defined as the amount of work that can be performed by force whereas power is defined as the rate at which work is performed. In exercise its the rate of performing muscular work with potential energy becoming work aka moving weight or heat aka you getting warm. Definition and Mathematics of Work.
An object with kinetic energy can do work by colliding with something. An object can have a value for the power without doing any work. Table of Contents What is Work.
Electrical power is defined as the rate of work done per unit charge or rate of energy transfer per unit time. Work is determined by factors like force and displacement on contrary power is determined by work done and time. Comparison chart Different Forms of Power and Energy There are different forms of energy.
Work is the amount of energy necessary to move an object from one point to another. The main difference between work and power is that work is the amount of energy transferred when an object is moved by an external force whereas power is the rate of work done. Work Formula Work Unit.
T Therefore energy is given as E VIt Energy is measured in joules or watts-sec. Contact us today and request a quote at 253. Energy is the strength needed to perform work while the rate at which work is performed is called power.
T Or I VR Thus E V2tR Definition of Electrical Power. Force is the strength of a push or a pull on an object. Main Differences Between Work and Power Work is the energy required to move an object whereas power is meant as the energy spent to move the object.
Such solutions provide economically and environmentally beneficial services.
