Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. It arises due to the interactions at the microscopic level between the surface irregularities and the adhesive forces between the molecules of the surfaces. Friction plays a critical role in our daily lives and in various physical systems. There are several key types of friction: 1. **Static Friction**: This is the frictional force that prevents two surfaces from sliding past each other when at rest.
