How to Calculate Work
Work is a scalar quantity with no direction. It transfers energy from one place to another. It has the SI unit of joule, the same as energy. It is named after 19th century English physicist James Prescott Joule. One joule is the amount of work done by one newton of force over a metre of distance. In practice, work is measured by the rate of displacement.
During a baseball game, a baseball player throws a ball with a force of 10 N and a force of 20 N. To calculate the amount of work, three quantities must be known: the force, the displacement, and the angle between the displacement and force. Once these three quantities are known, the equation for work is simple to use. The first step is to find the magnitude of the force. Once you know the magnitude of the force, the next step is to find the displacement.
Now we need to know the magnitude of the force. The force of the force is the work-energy ratio. We know that the force of a weight equals the mass of the object. If the weight is the same, then the displacement is the same. The same applies for a torque. The torque of a mechanical device is the amount of work required to move it. In contrast, a mechanical device produces a force of 10 newtons.
A force of 10 newtons equals two metres of displacement. A force of twenty newtons produces the same displacement of two meters. The work-energy ratio is the reciprocal of the two forces. The relationship between them is known as the erg/resistance, which is the ratio between the two forces. If you want to calculate the work-energy ratio of a machine, you must know the length of the path. When this relation is known, the resulting displacement is the amount of work.
A force of 10 newtons equals two metres. If a force of twenty newtons equals two metres, it is 20 newtons, and vice versa. Thus, the force of ten newtons is equal to two meters and twenty newtons are equal to twenty kilograms. This means that a displacement of ten newtons equals two tonnes is the same as a weight of twenty kilograms. The weight of the object is the displacement.
In other words, the force of ten newtons equals the mass of a kilogram. The weight of a kiloweight equals one kilogram. The weight of an object is equal to ten newtons. In a metric system, work is the mass of the mass. In the same way, a kilopound equals one gram. And a gram-centimetre equals one gram, and the force of a kilogram is the same.
