Today was pretty tough for me because we learned a lot of new and confusing stuff. We did a lab with scales and weights in order to determine the relationship between mass and weight. We had to incorporate some relatively new vocabulary such as, weight force, normal force, friction, and tention. These are all aspects of Free Body Diagrams, which was probably the most important thing we learned all day! We learned how to draw the different diagrams according to what forces were acting on each object! I thought doing the practice problems in the packets really helped me to understand Free Body Diagrams better!

This are examples of Free Body Diagrams, in these the forces are shown through the arrows. We learned to use subscripts when writing our Free Body Diagrams so that we knew what forces were acting upon what. They were confusing at first but I eventually got the hang of them.
Love the title :P I agree, the free body diagrams were confusing, but it did get a little better after putting it together with the word problems. Tuesday down, Thursday to go...
