work done vs power
The work-energy principle is a mathematical tool that works very well at predicting and explaining real world phenomena. Calculating the Amount of Work Done by Forces.

Work is the amount of force required to move an object by applying outside force while power is the degree at which work is done.
. Apply this to above formula then we get. Work depends only on the displacement and not on the amount of time required for the force to act in order to cause a displacement but power is that quantity that depends on the rate at. You must have energy to accomplish work - it is like the currency for performing work.
Energy is just a way to view the world. Most commonly force times distance. As we Know I Qt the rate of change of charge is equal to current.
Work is defined as the process of energy transfer to the motion of an object through the application of force. Is the capacity for doing work. W F θ r T θ 2 where.
Work done is actually the change in energy while power can be defined as the change in energy per unit time or describing the power in terms of work you can say that it is. Generally Power is expressed as. Work done is elaborated in such a way that it includes both forces exerted on the body and the total displacement of the body.
The faster you do the work the more power youve produced. To do 100 joules of work you must expend 100 joules of energy. Meaning both formulas can be used to calculate power.
The work done can be expressed as. But the fundamental definition of power is the latter. Definition of the Work Done.
Power can be derived as Multiple. W work done J Nm F force N s distance moved by force s For an angular motion. Work is measured in joules whereas power is measured in watts.
Work done by expanding gas Pressure Pa x Change in volume m 3 Simplified formula. This is usually represented as the product of force and displacement. Joule J is the SI unit of work whereas Watt.
If the object does any work the value of the. Power describes the rate of energy. Definition and Mathematics of Work.
Work done is actually the change in energy while power can be defined as the change in energy per unit time or describing the. W work Joules θ angle. Lesson 1 - Basic Terminology and Concepts.
Youre training for power if you are lifting fast and heavy together punching really hard or throwing a ball very. Power noun metonymy chiefly in the plural The people in charge of legal or political power the government. Conservation of energy links GPE KE and work done.
Work done is the same as energy transferred. This block is preceded by a. Power is the work done per unit of time.
An object can have a value for the power without doing any work. Power is the rate of transfer of energy or the rate of doing work. Both seem to be correct as another answer also points out.
