It is more elegant in classical mechanics to define the power as bf F cdot bf v for a single particle.

. The work done can be expressed as. Power represents how fast the energy was transferred. The SI unit of work is Joule J.

Work done is the same as energy transferred. Studying work energy power is important in terms of both acquiring knowledge and getting higher marks in the exam. The equation to calculate work is.

Conservation of energy links GPE KE and work done. Definition and Mathematics of Work. Work is the outcome of force F and displacement S in the direction of force thus the equation can be written as Work done Force x displacement or W FS whereas power is the.

The SI unit of power is Watt W. W work done J Nm F force N s distance moved by force s For an angular motion. Power describes the rate of energy.

W F θ r T θ 2 where. Work Force Displacement. Work represents the amount of energy transferred when doing something.

The following diagram gives the formula for power and work done. Ability to act regarded as latent or inherent. Energy is of two types mainly kinetic energy and potential energy.

Conversely power is indicated by formula P Wt. Scroll down the page for more examples and solutions on how to use the formula. Work is a scalar quantity.

You must have energy to accomplish work - it is like the currency for performing work. Calculating the Amount of Work Done by Forces. They are equal in magnitude but one or the other is typically shown as negative depending on the system and if work was done by the.

Power worktime Work force x distance Velocity distancetime Therefore power force x velocity Snatchs are power exercises lifting weights fast velocity is the speed. Power is the work done per unit of time. If you do 100 joules of work in one second using 100 joules of energy the power is 100 watts.

Work unit J joule Nm. Power is the rate of transfer of energy or the rate of doing work. The unit of energy is also Joule.

Answer 1 of 2. Power is the ratio between the work done. Is the rate of doing work or the.

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. Work and Energy. Another user pointed out that the work definition may be extendable to.

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. The work is denoted by the formula W FS. Capacity for action or performance.

Capability of producing an effect whether. Energy is a systems ability to do work. The faculty of doing or performing something.

Power is a scalar quantity. Work done by expanding gas Pressure Pa x Change in volume m 3 Simplified formula. To do 100 joules of work you must expend 100 joules of energy.

Power is the work done per unit of time. PediaaCom - Know about Anything. Work is measured in joules whereas power is.

Lesson 1 - Basic Terminology and Concepts. W work Joules θ angle.
