Day 44: Geometry and Physics

2013-11-04 08.45.29

 

Today we whiteboarded Practice 2 from this packet (which is the same as standard WS 1 from the modeling materials). This group was able to identify from the get go that the net force had to be down the incline, but they wanted normal force and gravity to be equal. All I asked was if there was a right angle anywhere in their Force Addition Diagram, and from there they were able to determine that Gravity had to be larger than the normal force.
