Forces
If the bike and rider are considered to be a single system, the forces that act on that system and its components can be roughly divided into two groups: internal and external. The external forces are due to gravity, inertia, contact with the ground, and contact with the atmosphere. The internal forces are caused by the rider and by interaction between components.

Famous quotes containing the word forces:
“Anarchism is the great liberator of man from the phantoms that have held him captive; it is the arbiter and pacifier of the two forces for individual and social harmony.”
—Emma Goldman (1869–1940)
“In literary circles, the men of trust and consideration, bookmakers, editors, university deans and professors, bishops, too, were by no means men of the largest literary talent, but usually of a low and ordinary intellectuality, with a sort of mercantile activity and working talent. Indifferent hacks and mediocrities tower, by pushing their forces to a lucrative point, or by working power, over multitudes of superior men, in Old as in New England.”
—Ralph Waldo Emerson (1803–1882)
“Physical love, so unjustly decried, forces everyone to manifest even the smallest bits of kindness he possesses, of selflessness, that they shine in the eyes of all who surround him.”
—Marcel Proust (1871–1922)
