Forces and Friction Worksheet (Key)
... • Friction is a force caused by two objects rubbing together. Friction acts in the opposite direction of motion. Friction keeps you from slipping when you walk. Friction also makes a car’s brakes work. • The amount of friction depends on two things: how smooth the objects are and how hard they push ...
