Labs!

Pendulum lab, purpose was to prove our derivation was correct, i.e. that omega = sqrt(g/L). This says omega does not depend on Mass or phi max.If omega doesn't depend on phi max (maximum angle from vertical) or Mass, period won't either. You should have calculated expected omega from above equation and compared it with 2 pi/Tmeasured and found percent error. Tmeasured is the period you measured with your stopwatch. Note T is one tenth the time t for ten cycles.

Archimedes lab. Prove FB is density of fluid x g x volume by using Vol = change in force from scale/(density x g) to find density of object and then compare that with known densities from values I gave you. If they match then your calculated volume is correct so the equation for FB is correct. Only then do you see if density x g x change in height x area = FB as it should. While the first part should give very accurate results the second part may have large errors since change in height can be hard to get correctly.

Many of you still confuse grams and kg etc. in your work. GET OVER IT.
