Static and Kinetic Friction
... 2.1 Static vs. Kinetic: There are two types of frictional forces, static and kinetic. Static friction is what keeps a resting body at rest. Kinetic friction is what slows down an object when slid on a surface. Any two materials have a static and kinetic coefficient of friction which represents how m ...
