Friction is a force which opposes relative motion when two solid bodies are in contact.
A coefficient of friction between two materials is a number. The coefficient of static friction is higher than the coefficient of dynamic friction.
The actual force of dynamic friction is always found by multiplying the normal force by the coefficient of dynamic friction.
The actual force of static friction is always less than or equal to that found by multiplying the normal force by the coefficient of static friction.
