There is static friction and kinetic friction

Explanation:

Kinetic friction is the force during motion and static friction is the force needed to be overcome to get a stationary object to begin moving.
Kinetic friction is usually much less than static friction
Both are proportional to the weight [Normal Force] of the object.
Both oppose motion.
