Today in class...
People who did not complete their lab from the previous class had the opportunity to continue their lab in class today. From the lab, u basically learn that the sum of the momentum of the target sphere and the incident sphere should be equal to the original momentum as such.
We also reviewed some things in class that we already learned. This includes:
P=mv
P=Ft
Ft=mv
For elastic collisions before and after collision:
m1v1 +m2v2 = m1v1 + m2v2
For non-elastic ("sticky") collisions in which the two objects travel together after the collision:
m1v1 +m2v2 = (m1 + m2)v2
Finally, we also received another worksheet in class today. It was a double-sided worksheet, one side entitled "Impulse and Momentum" and the other side entitled "Conservation of Momentum." You should complete the sheets in order to get practice and better understand the unit. I do not believe it is worth any marks, but i could be wrong.
Our test for the units on momentum and projectile motion will be held on Mar. 22. So don't forget to study. I believe that basically covers everything we did in class today so I guess I'm done. The next scribe will be Jeamille!
