Statics: Introduction to Friction, Slipping, and Tipping

EDITS
@ 00:41 I said "static" but meant "kinetic"
In this video we introduce the concepts of Friction, slipping (when we push an object and it slides), and tipping (when we push an objects and it rotates about a point and "tips" over).
In my opinion, this is all the knowledge you need to solve problems from this section. Other books/professors may present the 3 types of Slipping/Tipping problems:
1) No apparent impending motion
2) Impending motion at all points of contact
3) Impending motion at some points of contact
But think these are just more things that you have to memorize, and are not strictly needed. Solving problems from this section require using common sense and imagination, so let's work out some practice problems after you are done with this video!
Practice is the name of the game!
