Friction

Here are the solution from the chapter Friction from Nootan Physics - Part I...











Video lecture on Angle of Friction or Angle of Repose:



Forces (FBD) and Newton's Laws for Motion


Here is the Problem Solving Approach for drawing FBD's and thereafter selected solution to the problems from Nootan Physics...
How one should draw the Free Body Diagram's (FBD's), remembering these points would always help you to do that.
Watch these video's to understand the basic steps to be followed while drawing free body diagrams, they will build your approach towards numerical solving:













Different approach for finding the acceleration, considering the different connected bodies as a system and neglecting the internal forces...




Motion in 1- Dimension pg 1

Here are the selected solutions of Motion in 1-dimension from Nootan Physics - Part I...
13th and 18th solution has been given especially in vector notation first, so as to make the students aware of the use of vector sign convention in the problem solving technique, later all the solutions has been done without using the vector notations, but definitely the sign convention has been followed.

Alternative Method:
