Philosophers in [[antiquity]] have used the concept of force in the study of [[statics|stationary]] and [[dynamics (physics)|moving]] objects. [[Aristotle]] attempted to define this concept in detail but incorporated fundamental misunderstandings that lasted many centuries. [[Archimedes]] developed a better understanding of force by observing [[simple machines]], but many in his time still believed Aristotle's concept of force.<ref name="Archimedes">{{cite web |last=Heath,T.L. | url = http://www.archive.org/details/worksofarchimede029517mbp | title = ''The Works of Archimedes'' (1897).

With modern insights into [[quantum mechanics]] and technology that can accelerate particles close to the speed of light, [[particle physics]] has devised a [[Standard Model]] to describe forces between particles smaller than atoms. The [[Standard Model]] predicts that exchange particles called [[gauge boson]]s are the fundamental means by which forces are emitted and absorbed. Only four main interactions are known: in order of decreasing strength, they are: [[strong force|strong]], [[electromagnetic force|electromagnetic]], [[weak force|weak]], and [[gravitational force|gravitational]].<ref name="texts" /> [[High energy physics|High-energy particle physics]] [[observation]]s made during the 1970s and 1980s confirmed that the weak and electromagnetic forces are expressions of a more fundamental [[electroweak]] interaction.<ref name="final theory" />
