We've gone through this process with position-time graphs; velocity-time graphs; direction of force and motion; friction forces; forces in 2-d; collisions; impulse; and energy.
Eventually I will proofread all of these, compile them, make sure they work in multiple years, and publish them all. But for now, I offer this set of collision problems. These are particularly easy to set up if you have PASCO carts and tracks.
Posts I intend to write soon: The baseball schedule is pretty crazy right now. I'm umpiring or broadcasting five games a week for the next month. Yet I am still here and willing to write about physics! Soon, perhaps, I will get to:
* Why the in-class lab exercises have worked well in ninth grade, but I have no intention of every trying them in 12th grade classes
* a fishing line experiment with impulse
* Our overall, full-year conceptual physics outline -- would you like to take our exam?
* Any and all of your AP physics 1 questions, after I get back from the April 20-21 consultant training.
Please send any other requests via email, and I'll see what I can do.
