Need to find out how much power a device has without having to do a lot of complex? If so, this Work and Power Calculator will come in helpful. This tool aids in the rapid discovery of power. Learn more about the step-by-step procedure for calculating power using work and time. Also, in the parts below, you can find solved examples and formulas to test the power.
Work - Definition
In physics, the quantity of energy required to move an object a specific distance is referred to as work. It could be the energy expended lifting big bags up the stairs or the kinetic energy expended when the body moves.
Force multiplied by the distance an object goes is how it's usually computed. Between these two quantities, it's a dot product. It is expressed in joules (J) or kilowatt-hours (kWh).
Power - Definition
The rate of change of work, or the amount of work completed in a given amount of time, is referred to as power. The higher a device's power, the more work it can do in a given amount of time. It is expressed in units Watts(W), which is equivalent to SI unit of kg·m²/s³.
Power and Work Formulas
The formulas for calculating power and work are given below
Work W = force x displacement
Power P = W/T
- Where,
- W = work done
- T = time
- P = power

FAQs on Work and Power Calculator
1. What units are used to calculate work and power?
The joule (J) is a unit of work that is equal to kgm2/s2 in SI units. The kWh is another standard unit of work.
The watt (W) is a unit of power that measures the number of joules of work done per second.
2. How many joules are in a kilojoule?
A kJ is equal to 1,000 joules (kilojoule). When the letter k appears in front of a unit, it signifies the unit has been multiplied by 1,000.
3. What is the formula for calculating work energy and power?
Multiplying the force with the displacement. The product of force and velocity, or the divide of work and time, is power.
4. How to calculate power?
The steps to calculating an object's mechanical power are basic and straightforward. Follow these procedures to achieve your desired outcome.
- Take the values from the question for the task and the time it takes to complete it.
- Divide the work by the time you've spent working on it.
- Power is the end outcome.
5. One horsepower equals how many joules?
735.5 watts, or joules per second, equals one horsepower. So, if you labor at one horsepower for one second, you'll get 735.5 joules. To find the total energy in joules, multiply the work duration in seconds by the total energy in joules.
