The diagramm depicts Galileo's thought experiment on on inertia. He thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill. Using this logic, as the ramp approaches a level surface, the ball will roll forever. Thus no force is needed to keep an object moving with constant velocity.

Often inertia is loosely described as a form of resistance, but inertia is quite unlike that. Friction is a form of resistance. Friction is usually roughly proportional to the velocity. If the driving force is doubled then a higher top speed may be attained. When inertia is the only impediment, then doubling the exerted force doubles the acceleration. Inertia does not relate to velocity, inertia relates to the
