work done vs power
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 fraction of work and time worktime so the equation is written as Power Work done Time taken or P W t. 2Power is used more often than work.

An object can have a value for the power without doing any work.
. 1 Btu thermochemical 105435 J. Work is determined by factors like force and displacement on contrary power is determined by work done and time. It exists in various forms like potential kinetic chemical thermal nuclear electrical energy and so.
Work can also be measured in units like electron volt eV kWh MWh and GWh. W Δ K E 1 2 m v 2 2 1 2 m v 1 2. If the object does any work the value of the power cannot be zero.
Force Energy applied to an objectMeasured in Newtons. Work is measured by Joule J. Work Energy and Power are fundamental concepts of Physics.
Power is also a scalar quantity. Calculate electrical power and cost of using electricity. Calculating the Amount of Work Done by Forces.
Power Force Velocity. 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. Define energy and list different types of energy.
Work is a scalar quantity. Work is the displacement of an object when a force push or pull is applied to it. W Δ K E 1 2 m v 2 2 1 2 m v 1 2.
1 2 m v 2. Define power and its equation. It is the worktime ratio.
Power is the rate at which work is done measured in watts W in other words the work done per second. Nature of the quantity. Power worktime Work force x distance Velocity distancetime Therefore power force x velocity Snatchs are power exercises lifting weights fast velocity is the speed in which you lift the weight.
W F θ r T θ 2 where. Power is the rate of transfer of energy or the rate of doing work. For example the work done against gravity is equal to the change in the potential energy of the body and the work done against all resistive forces is equal to the change in the total energy.
The amount of work done by a steady force is the amount of force multiplied by the distance an object moves parallel to that force. Is the rate of doing work or the rate of using energy which are numerically the same. Power is the rate at which work is done.
Power Work time or P W t. Mathematically it is computed using the following equation. Name and describe different forms of energy.
W 100 N 50 m 5000 Nm J The unit of work is joule J which is defined as the amount of work done when a force of 1 newton acts for a distance of 1 m in the direction of the force. When a car stops 40000J of work is done by the brakes in a time of 5s. W F x cos θ.
Definition and Mathematics of Work. Main Differences Between Work and Power. Power is a scalar quantity.
The work done by a force 100 N moving a body 50 m can be calculated as. Example - Work due to Gravitational Force. Explain how force energy and work are related.
Work represents the amount of energy transferred when doing something. Andersen defines the terms energy work and power. W work done J Nm F force N s distance moved by force s For an angular motion.
Work done is the same as energy transferred. 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. The work done can be expressed as.
The SI unit of power is Watt W. Lesson 2 - The Work-Energy Relationship. The following diagram gives the formula for power and work done.
1 Btu 2519958 calories. The quantity that has to do with the rate at which a certain amount of work is done is known as the power. Summary of Force Work and Power.
Work Force X Distance or the amount of heat transferred Measured in Joules or calories. Power WorkTime Measured in Watts Various Energy Units. To do 100 joules of work you must expend 100 joules of energy.
If you do 100 joules of work in one second using 100 joules of energy the power is 100 watts. Conservation of energy links GPE KE and work done. W work Joules θ angle.
Difference Between Work and Power Definition of Work and Power. Power is the rate of work done. This is a statement of the workenergy theorem which is expressed mathematically as.
It turns out that. This article discusses work energy and power in detail. Scroll down the page for more examples and solutions on how to use the formula.
He also uses a simple example to calculate both work and powerIntro Music AtributionTitle. Work is defined as the work done by an object is equal to the scalar product of force and displacement and The power of a source is defined as the rate of doing work. Work Force Displacement.
Work is the energy required to move an object whereas power is meant as the energy spent to move the object. Power is the ratio between the work done and the time taken and can be expressed as. The hiker has a greater power rating than the rock climber.
Power represents how fast the energy was transferred. The SI unit of work is Joule J. 1 2 m v 2.
1 calorie thermochemical 4184 J. The equation to calculate power is. Calculate work done by multiple forces.
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 work done per unit time. Work is a scalar quantity. You must have energy to accomplish work - it is like the currency for performing work.
1 J 1 Nm. The units are N. Lesson 1 - Basic Terminology and Concepts.
R radius m T torque or moment Nm Power transmitted. AP Physics 1- Work Energy Power Practice Problems ANSWERS FACT. We define the capacity to do the work as energy.
The equation to calculate work is. Work is the amount of energy transfer when an object is moved by an external force. When work done on an object increases only its kinetic energy then the net work equals the change in the value of the quantity.
Work is measured in joules whereas power is measured in watts. Power is the work done per unit of time. Example - Work done by a Force.
1Power is the rate at which work is being done.
