Force of friction
a force that opposes motion between surfaces that are touching
the force that opposes the motion of two touching surfaces is velocity.
Between any two body surfaces in contact there acts an frictional force. A friction can operate between a given pair of solids, between a solid and fluid or between a pair of fluids. There are two types of frictional forces : kinetic and static friction. When two bodies in contact move with respect to each other , rubbing the surfaces in contact the friction between them is called kinetic friction. The directions of frictional forces are such that it opposes the relative motion. Friction forces can also act between two bodies which are in contact but not moving or sliding with respect to each other. The friction in such case is static friction.

There are many types of forces that oppose motion such as friction, drag and most universal, gravity.

Friction
the force that opposes the motion of two touching surfaces is velocity.
The force that opposes motion between two surfaces that are touching each other is called friction. Friction occurs because of the interactions between the molecules on the surfaces in contact.
The force that opposes the sliding motion of two surfaces touching each other is called friction. Friction occurs due to the interactions between the irregularities on the surfaces, which creates resistance to motion.
The force that opposes the sliding motion of two surfaces that are touching is called friction. Friction is a force that acts in the opposite direction to the direction of motion, and it arises due to the interactions between the surfaces at a microscopic level.
The force that opposes motion between two surfaces that are touching is called friction. Friction occurs due to the microscopic roughness of surfaces coming in contact with each other, causing resistance to motion. The two main types of friction are static friction, which prevents surfaces from starting to move, and kinetic friction, which opposes the motion of surfaces that are already in motion.

a force that opposes motion between surfaces that are touching
Friction is a force that opposes motion between two surfaces in contact with each other. It acts in the direction opposite to the motion of the object.
