Webfriction: [noun] the rubbing of one body against another. the force that resists relative motion between two bodies in contact.

WebHow Does Friction Work? In order to control friction, we must understand it. Friction results from two bodies interacting at their contact surfaces — it’s the force that tries to resist movement between those two bodies. There are two types of friction: static and kinetic. The maximum friction force for either case is defined by:
