Lab 7: Friction Multi-blocks
... Friction is everywhere. In introductory physics, professors often present problems by saying “assume there is no friction,” but we can’t just ignore it in the real world. In general, friction is the force that slows down the motion of an object. The force of friction is directed along the surface of ...

... Newton’s Law of Inertia describes two states of equilibrium: static equilibrium (without motion) and dynamic equilibrium (with motion). If an object is in dynamic equilibrium, it can either move in a straight line at a constant speed (Fnet = 0) or it can spin at a uniform rate (cw net = ccw net). ...
