I'm opposed to any sport that reduces the coefficient of friction between me and the ground.
Cadmium is used in many kinds of solder and bearing alloys, because a low coefficient of friction and fatigue resistance.
For example, silicone rubber or acrylic rubber -coated surfaces have a coefficient of friction that can be substantially larger than 1. While it is often stated that the COF is a "material property," it is better categorized as a "system property."
However, the coefficient of friction is not a function of mass or volume; it depends only on the material.
If friction cannot do this (that is, the coefficient of friction is exceeded), the ball slides to a different radius where the balance can be realized.
In this case, the magnitude of the friction force is the product of the mass of the object, the acceleration due to gravity, and the coefficient of friction.
