Homework Statement
In describing a wheel's circular motion: "Circular motion arises purely from the resistance of the ground upon which it is applied…this resistance is equal to the force which draws the wheel in the right line"
Homework Equations
F=m(v^2/r)
The Attempt at a Solution
Is this talking about how the only forces acting on the wheel is the normal force and gravity, thus making the centripetal force? How is this equal to the force which draws the wheel forward in linear motion?
