friction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.

Static friction is the frictional force between two substances ' surfaces when they are not in movement. Therefore, in this case, the bodies are stationary in relation to each other instead of the bodies being in relative motion.
Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.
Two solid objects moving against each other experience kinetic friction. Friction also acts in stationary objects. Static friction prevents objects from moving and is generally higher than the frictional force experienced by the same two objects when they are moving relative to each other.
The direction of friction is always opposite that of motion, parallel to the surface between objects, and perpendicular to the normal force.
Types of Frictional Forces
- Static Friction.
- Kinetic Friction.
- Rolling Friction.
- Sliding Friction.
Even though they act in the direction opposite to that in which an object moves, the normal force (FN) produces these forces, which acts perpendicular to the direction of motion. For example, if you press down on a block of wood on a table, you increase the normal force, and thus it increases the frictional force.
