In case of pure rolling
Weband the equation of rolling contact is First, we eliminate from the equations of motion to give Note that so the spin in the direction normal to the plane is constant, say. (Both forces on the sphere have zero torque about this axis.) Integrating, Now eliminate by multiplying both sides by and using the equation of rolling contact to find: WebAssertion: In case of pure rolling, the force of friction becomes zero.
