Collision lab
Using sensors on an air track, we will attempt to use the mathematics of collisions to "weigh" an unknown mass.
Each team will make its own determination, and the class average will be used to determine a scientifically valid answer.
"Standard error of the mean"

Practice problem questions
Demonstration of momentum, continued:
Air track
Air table
dart into clay
Which is better for knocking someone down: a bullet made of metal or rubber?
coefficient of restitution (and how to test it)
Using conservation of momentum in anti-collisions such as rocket engines and explosions
The impulse-momentum relation revisited: can you use it to explain everyday phenomena such as car air bags?
Questions about the egg drop, including the due date. We will hold the drop on December 16.
