Chemistry 9-27-11 Law of Conservation of Mass Lab

CHEMISTRY – Great job on the lab today. So did you see the Law of Conservation of Mass today? Why not? What are you going to do differently in the lab tomorrow, and why do you think it will work? Here’s the the format for Part 1 and 2 of the lab write up, just in case you didn’t get it in class today: CONSERVATION OF MASS Lab Report. Don’t forget – short classes tomorrow, so you need to come to class moving quick like a bunny!

Physics 9-27-11 Angular Projectile Motion

PHYSICS – Great job today! Here’s the lecture from Tuesday on angular projectile motion. The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!
