Physics Of Work And Power Flash Cards Work Energy And Power Physics Lessons Power Physics
1Power is the rate at which work is being done.
. W work done J Nm F force N s distance moved by force s For an angular motion. 1 Btu 2519958 calories. Conservation of energy links GPE KE and work done.
Lesson 2 - The Work-Energy Relationship. Power represents how fast the energy was transferred. Main Differences Between Work and Power.
Definition and Mathematics of Work. Nature of the quantity. 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.
Is the rate of doing work or the rate of using energy which are numerically the same. Work is measured in joules whereas power is measured in watts. The SI unit of power is joulessecond or Watt.
Power is the work done per unit of time. 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. This article discusses work energy and power in detail.
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. The energy that the object consumes on average working per unit time is average power.
It exists in various forms like potential kinetic chemical thermal nuclear electrical energy and so. The power is directionless and thus a scalar quantity. It is the worktime ratio.
Assume ρo and α are positive. W work Joules θ angle. Calculating the Amount of Work Done by Forces.
12 hours agoWork done here is called potential of q at A. Power is also a scalar quantity. The SI unit of power is Watt W.
Summary of Force Work and Power. Work is measured by Joule J. Power is the rate of transfer of energy or the rate of doing work.
Force Energy applied to an objectMeasured in Newtons. Power is the rate of work done. Power is the ratio between the work done and the time taken and can be expressed as.
Com E-Field and Electric Potential for a thick shell of charge with a ρr ρo Exp-αr A thick non-conducting spherical shell of inner radius a and outer radius b has a volume charge density ρr ρo Exp-αr for a r b. The equation to calculate power is. Difference Between Work and Power Definition of Work and Power.
Work Force Displacement. Mathematically it is computed using the following equation. Power is a scalar quantity.
Work Energy and Power are fundamental concepts of Physics. To do 100 joules of work you must expend 100 joules of energy. Lesson 1 - Basic Terminology and Concepts.
Work is defined by factors such as force and displacement whereas power is defined by work done and time. The work done by a constant force is visualized in the chart above. If you do 100 joules of work in one second using 100 joules of energy the power is 100 watts.
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. This video covers- The two definitions of power- Difference between energy transferred and work done- How to use the power equation General info- Suitable. Work can also be measured in units like electron volt eV kWh MWh and GWh.
The SI unit of work is Joule J. Work is the displacement of an object when a force push or pull is applied to it. Work is determined by factors like force and displacement on contrary power is determined by work done and time.
You must have energy to accomplish work - it is like the currency for performing work. 2Power is used more often than work. 1 calorie thermochemical 4184 J.
The equation to calculate work is. The quantity that has to do with the rate at which a certain amount of work is done is known as the power. Their units are different but the concept is similar.
1 Btu thermochemical 105435 J. The hiker has a greater power rating than the rock climber. The work done can be expressed as.
Work is a scalar quantity. The work is the product force x distance and represented by the area as indicated in the chart. This is the same unit as energy.
Power is the rate at which work is done. 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 Work time or P W t.
Work represents the amount of energy transferred when doing something. 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. 1 ft lbf foot pound force 13558 J 01383 kp m 3766x10-7 kWh 3238x10-4 kcal 1285x10-3 Btu.
Work is defined as the amount of energy required to move an object whereas power is defined as the amount of energy expended to move the object. We define the capacity to do the work as energy. Work is the energy required to move an object whereas power is meant as the energy spent to move the object.
Work is the amount of energy transfer when an object is moved by an external force. An object can have a value for the power without doing any work. Here in the context of work and energy power is simply the rate of doing work.
Work Force X Distance or the amount of heat transferred Measured in Joules or calories. Work done is the same as energy transferred. If the object does any work the value of the power cannot be zero.
R radius m T torque or moment Nm Power transmitted.
