Physical Work Calculator

Calculate the work from force and distance, with different units. In physics, work is a form of energy. Work on a body is performed, when over a distance a force acts. The formula is W=F*d. The unit of work is joule, which is identical to newtonmeter or force meter and watt-second, J=Nm=Ws. One watt-hour is 3600 watt-seconds. Force can be in newtons and ponds. For the distance, metric units as well as inches, feet, yards and miles can be selected.

Example: if over a distance of 250 meters a force of 1.2 kilonewtons acts, then a work of 300 kilojoules or 0.0833 kilowatt-hours is done.

Physical or mechanical work is that form of energy in which a force acts over a certain distance. To simplify matters, it is often assumed that the force is constant over the entire distance. This can be seen in a weight that is hanging on a rope and being pulled upwards. The force is then calculated from the mass of the weight in kilograms and the location factor, which on earth is about 9.81 Newtons per kilogram. Finally, the work is the force times the distance over which it is pulled. It is irrelevant how fast it is pulled for the work. If the speed is also to play a role, then the power can be calculated, which is a measure of the work per time.
The force is often not constant. If you pull on the rope with your hands, you will hardly be able to do it over a longer distance with constant force. Nevertheless, for the same distance, the work is the same.

The different units for work in particular and energy in general are the same. However, the joule or kilojoule is more common for work, whereas the watt hour or kilowatt hour is preferred for other types of energy, such as electrical energy. To give an idea of ​​the magnitude: one kilowatt hour is equal to 3.6 million joules.
