... A person stands on a bathroom scale in an elevator at rest on the ground floor of a building. The scale reads 836N. As the elevator begins to move upward, the scale reading briefly increases to 935N but then returns to 836N after reaching a constant speed. a) Determine the acceleration of the elevat ...

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 ...

... Static Friction: Push with a force F and block does not move because fs = F. The force of friction varies from 0 up to some maximum. The maximum value equals fs = msN, where N is the normal force. Above we would have fs = msmg. The coefficient of static friction ranges from 0 to 1.2 Kinetic Friction ...
