Physics 30 - Feb 29

Today we started our second unit on dynamics.  We learned what forces are, general types of forces as well as some of the specific forces that we will be studying.  We also learned what a net force is as well as how to determine the net force.  A new type of diagram was introduced which was the free body diagram.  The FBD for short, will be a vital component to solving problems involving forces.  Assignment 2.1 was assigned and we will take up this assignment on Wednesday.  This was all covered on slides 1-15 on the new powerpoint in the Unit 2 folder.
