Work

Work can mean different things depending on how the word is used.

• When used in a sentence as an action, work means doing something that requires labor.

• When used in a sentence as an object, work means something that remains to be done.

• A worker is any person that does work, often in exchange for money or helpful services (these workers that receive money or helpful services are said to be "holding a job").

• In science, mechanical work is done when a force is applied to an object and a resulting movement takes place against some resistance to the movement. An equation for the total amount of work produced from a force is Work = force x distance. As a result of the work the object will have gained energy, either as heat , a change in its velocity or a change in its position in space. If something can do a lot of work in a short time it is said to be powerful. Doing the same amount of work over a longer time will transfer the same amount of energy but will require less power.

• The phrase "work ethic" is used to explain how hard a person works, and what his or her attitude towards work is.
