The force that one surface exerts on another surface when two objects rub against each other?

• friction

• gravity

• inertia

• balanced force

An object at rest will remain at rest unless acted upon by an unbalanced force. Likewise an object in motion will remain in motion unless acted upon by an unbalanced force.

• Newton's 2nd law

• Newton's 3rd law
