Forces and Friction Worksheet
... • 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 ...

... for any problem that involves forces acting on a body in equilibrium. Remember that “equilibrium” means that the body either remains at rest or moves with constant velocity. For example, a car is in equilibrium when it’s parked, but also when it’s driving down a straight road at a steady speed. If t ...
