What's the difference between 仕事 and 働く?


Apart from 働く being a verb, and 仕事 being a (suru) noun, what is the difference
between the two?




They(仕事する and 働く) mean "to work in a company or as a one-person operation" and
also "to do something".

However 働く has some meanings besides like 作用する(act on). For example,
地球では重力が働く(Gravity acts on the earth)
