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:
“The next thing his Lordship does, after clearing of the coast, is the dividing of his forces, as he calls them, into two squadrons, one of places of Scriptures, the other of reasons....
All that I have to say touching this, is that I observe a great part of those his forces do look and march another way, and some of them fight amongst themselves.”
—Thomas Hobbes (1579–1688)
“Is there something in trade that dessicates and flattens out, that turns men into dried leaves at the age of forty? Certainly there is. It is not due to trade but to intensity of self- seeking, combined with narrowness of occupation.... Business has destroyed the very knowledge in us of all other natural forces except business.”
—John Jay Chapman (1862–1933)
“The most exciting happiness is the happiness generated by forces beyond your control.”
—Ogden Nash (1902–1971)
