Question

does the area of contact affects the frictional force
​

Answer 1

Answer:

Friction is a contact force when two surfaces interact. ... Notice that both of these friction formulas ONLY depend on the coefficient of friction and the normal force. It does not depend the area of contact, it doesn't depend on the sliding speed.
