Work (also known as mechanical work) is the transfer of energy from one object to another. Work can be accomplished by applying a constant force to an object that causes it to move in a particular direction, or simply by changing the shape of the object. The amount of work done on an object is calculated by multiplying the force exerted by the displacement. The unit used for measuring work is the joule, which is equal to one newton-meter per second squared. Work can also be achieved by compressing a gas, rotating a shaft, and other actions that do not involve physical displacement but which increase the internal energy of an object.
A central aspect of the modern world, work provides an individual with a sense of purpose and meaning, as well as financial means. In addition, it plays a key role in social exchanges and in the development of personal identities. In many societies, work has also become a key aspect of the process of integration into a given society, especially in its capacity to create an opportunity for individuals to interact with different groups and communities.
