Chapter 10 TEST - Study Guide
... The force that two surfaces exert on each other when they rub against each other is called Friction. It acts in a direction opposite to the direction of the moving object. Friction will eventually cause an object to come to a stop. The strength of the friction force depends on two factors: how hard ...
