If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, friction slows a hockey puck sliding on ice. When objects are stationary, static friction can act between them; the static friction is usually greater than the kinetic friction between two objects.

31 Αυγ 2015 · The main difference between static and kinetic friction is that static friction acts while the surfaces are at rest while kinetic friction acts when there is relative motion between the surfaces.
23 Μαρ 2022 · Static and kinetic friction are fundamental concepts in the field of physics, governing the motion of objects and the forces that act upon them. Understanding the nuances of these two types of friction is crucial for students studying mechanics, engineering, and related disciplines.
A General Rule: Kinetic (sliding) friction is less than static (not moving) friction. Because moving surfaces are bouncing off each other with little less surface area interaction. Rolling Friction would have less friction (opposing force) than static or kinetic sliding friction.
