... 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 ...

... Sample Problem – 3rd Law A tug-of-war team ties a rope to a tree and pulls hard horizontally to create a tension of 30,000 N in the rope. Suppose the team pulls equally hard when, instead of a tree, the other end of the rope is being pulled by another tug-of-war team such that no movement occurs. ...

Lab: Centripetal Force
... The purpose of this lab is to investigate the relationship between the velocity of an object in uniform circular motion and the centripetal force on the object. Variables: Radius of circular motion (r): The horizontal distance measured from the top of the tube to the stopper when the stopper is sw ...
