For a uniform ball rolling down an incline with angle theta, a coefficient of proportionality associ
For a uniform ball rolling down an incline with angle theta, a coefficient of proportionality associated with this quantity must be at least two-sevenths tangent theta to prevent slipping. A slipping ball, however, requires a different coefficient associated with the quantity, because the coefficient depends on whether or not the contact points are moving. Both the static and kinetic type of this force are proportional to the normal force. For 10 points, name this force that opposes the direction of an object's motion.
