Rolling Friction on a Wheeled Laboratory Cart
Mungan, Carl E.
Physics Education, v47 n3 p288-292 May 2012
A simple model is developed that predicts the coefficient of rolling friction for an undriven laboratory cart on a track that is approximately independent of the mass loaded onto the cart and of the angle of inclination of the track. The model includes both deformation of the wheels/track and frictional torque at the axles/bearings. The concept of rolling friction is contrasted with the static or kinetic friction that in general is also present, such as for a cylinder or ball rolling along a horizontal or inclined surface. (Contains 2 figures.)
