The frictional force is a force that naturally arises between two surfaces in contact as they move or attempt to move against each other. It is the force that resists relative motion and is a common and natural force found in various everyday interactions.
- Electric force and magnetic force are non-contact forces that act through fields, while gravitational force is also a non-contact force but acts due to mass and distance.
- Frictional force is the natural force that resists the sliding of objects in contact and is often encountered in practical scenarios.
