There are more units if you get into electricity and magnetism.

. Conversely power is indicated by formula P Wt. Conservation of energy links GPE KE and work done. Work is measured in joules whereas power is measured in watts.

An object can have a value for the power without doing any work. Work can also be measured in units like electron volt eV kWh MWh and GWh. This physics video tutorial provides a basic introduction into work energy and power.

Definition and Mathematics of Work. Lesson 1 - Basic Terminology and Concepts. The SI unit of power is Watt W.

Now we will perceive how to determine work done. This article discusses work energy and power in detail. The work is denoted by the formula W FS.

Power represents how fast the energy was transferred. Power is the work done per unit of time. Well power is defined as the amount of work done per second and it is measured in watts or joules per second.

The equation to calculate power is. 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. This video covers- The two definitions of power- Difference between energy transferred and work done- How to use the power equation General info- Suitable.

Apply the work equation to determine the amount of work done by the applied force in each of the three situations described below. Work done is the same as energy transferred. The energy decreases when negative energy is completed and the energy increases when positive work is completed.

But slope is defined as the change in y over the change in x and if your y axis is work and your x axis is time the slope becomes work over time which is power. If the object does any work the value of the power cannot be zero. Power is a scalar quantity.

It discusses the work-energy principle the relationship between wor. We know energy can neither be formed nor be demolished so the energy must be converted into some other form. Work represents the amount of energy transferred when doing something.

W 100 N 5 m cos 0 degrees 500 J. Calculating the Amount of Work Done by Forces. Is the rate of doing work or the rate of using energy which are numerically the same.

The equation to calculate work is. Joule J is the SI unit of work whereas Watt W is the SI unit of power. Power is the rate of transfer of energy or the rate of doing work.

You must have energy to accomplish work - it is like the currency for performing work. 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. To do 100 joules of work you must expend 100 joules of energy.

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. Lesson 2 - The Work-Energy Relationship. When done click the button to view the answers.

If you do 100 joules of work in one second using 100 joules of energy the power is 100 watts. In this stance it is termed as work done. The SI unit of work is Joule J.
