Day 84: Relative Velocity Success!

Screen shot 2013-01-22 at 7.45.14 PM

I wrote previously about a new demonstration I was planning to aid in teaching relative velocities. I would love to have students do it, but the setup, including the camera in the ceiling, was a bit too intense once I did a quick cost/benefit analysis of the gain for that vs. doing it as an interactive demo. I think it really helped in their understanding of how velocities can add, but we’ll see when we whiteboard some problems tomorrow.

We looked at some plane landings too. It’s pretty fun pausing it before the first one touches down and forcing them to draw the vector addition diagram before letting them see the result!
