Work is the process of transferring energy from one place to another by a force. This can be done by a machine, or by a person exerting a force on an object. Although a machine may change the distance between two points, the amount of work it does is limited.
There are three primary factors that determine the amount of work done. These are the force, the displacement and the magnitude. Using these three criteria, the work performed by a given force is a measure of how much energy was transferred to the object. Similarly, the displacement of the object is a measure of how far the object was moved. The work performed by a given force can be computed by multiplying the length of the path by the force component.
A joule is a unit of work that is used to measure how much work was done by a given force. One joule is the result of a force of one newton acting through a displacement of one metre. It is named after the 19th century English physicist James Prescott Joule. Other units of work include horsepower-hour and litre-atmosphere. However, the joule is rarely used for these purposes.
To calculate the amount of work required to move a heavy object from A to B, you need to know how far the object needs to be moved. Generally, the larger the force and the greater the distance, the more work the object will require. In addition, you also need to take into account the fact that the force is not stationary, but changing its direction. For example, when a car travels at 5 meters per second, the work it does is a lot less than if it traveled at a slower rate.
Another way to calculate the amount of work a force of a given size and strength would require is to determine the angle of the force. If the force is at a right angle to the displacement, then the amount of work incurred is zero. On the other hand, if the force is at a wrong angle, then it is the opposite. Thus, it is only when you have both the correct angles that you can accurately calculate the work incurred.
A more practical example would be the cosine function, which is the inverse of the square root of the magnitude of the force. When you do this, the resulting equation is a bit more complex, but it still tells you how much work you will need to do.
