Electrical work and magnetic work are other types. It might be more accurate to say that work is energy transfer not involving heat transfer or mass transfer—that is, energy transfer not driven by a temperature or chemical potential gradient, respectively.

Work and power might appear similar to each other as both involve energy but they have differences, in scientific terms. There are mainly 5 differences between work and power that one should always remember while discussing the terms work and power or if we want to differentiate between work and power.
Before we explain the difference between work and power, let us have a look at what do we mean by the terms work and power individually. Now, what is work? Work and Energy are the two terms frequently used in everyday life. We know that both work and energy are two interrelated topics that play an important role in the world.
Before understanding the scientific meaning of Work in the context of physics, in general, we can say Work is just Energy transferred by force. Whenever we exert force on an object or a body, it is evident that there will always be some changes, if you push a box placed on the floor it will move, which can be put forward by saying, a force was applied resulting in work.
To lift a box or open a closed-door, all we are doing is spending some energy which is depending on the amount of force applied, in other words, the amount of energy required to push the box or lift the box from the ground.
Work done is defined as, when an external force is exerted on a body in steady motion or at rest , it will experience some displacement, this action is termed as the work is done. Work is said to be done when:. Image will be uploaded soon. Work done can be mathematically expressed as follows,. F - External force applied. Now let us see what is power? So, the power of a source is the rate of doing work.
Like in regular basis work is defined as some activity of a person. The SI unit of work is joule J. Work done is said to be the energy transferred. Work done by a force of 1 newton in moving an object through a distance of 1 meter in the direction of force. There are few factors that affects work, those are;. Work done by gravity on an object is considered zero, as the object experiences zero force when the angle of displacement is perpendicular to the direction of force.
To calculate work done in physics there is a formula;. Some examples of work are; pushing the car horizontally from rest, shooting a bullet, book falling from the table, walking upstairs, sawing the log, etc.. These examples are taken from regular life scenarios, which justifies the definition of work. Power is the rate of doing work. It can be defined as the rate at which energy is spent.
The definition in physics of power is somewhat different from what it is used in context on a regular basis in life. Almost all devices use power ratings to indicate how much power they need in order to function. Values for work are of lesser importance and are more difficult to relate to in the real world as the actual amount is very variable depending on the length of usage, distance travelled, and the like.
Power is the rate at which work is being done. Power is used more often than work. Cite APA 7 , l. Difference Between Work and Power. Difference Between Similar Terms and Objects. MLA 8 , lanceben. Name required. Email required.
