Conquer That Castle - Catapult Project and Labs.Used in my General Physics classes.
Created by Roberta Tanner, modified from ideas found in The Physics Teacher (and possibly elsewhere - let me know if I'm missing a reference)
I've used the catapult prompt several times but the associated labs are new based on a recent article in The Physics Teacher. I crave suggestions and feedback if you read, modify, or try these.


ASU's Modeling physics program has their Mechanics materials online for FREE:

Momentum Notes: Here are my notes from the chapter on Momentum. It's basic, but I feel sums up the important definitions in a small package. I always have my students read these notes before we begin the chapter.

Lab:
Created by Doug Hutton and Josh Steffenson
Lab: This is another approach to the lab immediately above, without the video analysis. The masses entered are for the Fisher Scientific 2-dimensional collision apparatus, but should be easily changeable to the incident and target spheres of your choice.
Created by Chris Becke, (Heavily adapted from the following labs from The Physics Classroom and Jim Burke, Riverview HS)

Adjustable Momentum Problems - A way to quickly generate very simple momentum problems with answers.
~ Dan Hosey

Two-dimensional collision lab - Students measure the incoming and outgoing momentum of a collision between 2 hovercraft (KickDis type pucks, see PASCO website)
~ Dan Burns

Rocket lab -Students measure the impulse of a model rocket engine. See my video instructions here:

Automobile Reconstruction Activity - based on Bernard J. Feldman. “Elementary Physics in a Real Automobile Accident.” The Physics Teacher.
vol. 35, no. 6 (September 1997): 335-338

Ballistic Pendulum Demo - A .177 caliber pellet is fired into a can of clay, find the initial speed of the bullet. Powerpoint slides and slo-mo movie, New! IR video of bullet hitting clay. - Dan Burns



AP Physics 1 Momentum Problem Set - Problem set built by Bob Enck, Dan Fullerton and Paul Sedita in an effort to start an AP-1 style problem bank. Feel free to print/use in your classrooms. Please don't re-post the files themselves, but rather only the links to the files, to allow us to quickly and easy update and continue to build upon these problems. Thank you! -- Dan Fullerton (dfullerton@aplusphysics.com). PS - anyone interested in adding on to these problems, we'd love the help!

Inelastic Collision Demo Lab - This is a good introduction to momentum. Students discover momentum conservation after observing inelastic collisions between dynamic carts. It could easily be adapted to be a student performed lab. - Dan Burns


Momentum Collisions Lab Written by Valerie Risk
Students model 4 real-world scenarios using Vernier tracks, carts and motion sensors. They analyze the velocity graphs and calculate total momentum before and after each collision. In this version, they also calculate KE before and after. Then they make up their own 5th scenario and model it. Also see instructions on using logger pro - you have to make one of the graphs negative, because the two motion sensors are facing opposite directions.




A Sequence of Four Impulse Labs: - Jeff DeCurtins
Lab 1: Impulse from a constant force: using modified Atwoods, compare integral of Fdt with Delta p
Lab 2: Impulse from a variable force: using stretched springs for variable force, compare integral of Fdt with Delta p
Lab 3: Modeling Impulse Forces: record actual impulse force as function of time then model as triangle and half sine curve and compare integral to recorded F(t)
Lab 4: Impulse with variable mass: chain falling into cup mounted on force sensor. students measure F(t) then derive expected F(t) and compare
