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....
