Day 170: Conservation of Momentum

Thursday, 11 May 2017


Broke out the photo gates for the first time this year.

I’m not a fan of photo gates in my labs because I think the setup time is too expensive for the results. Instead, I have students use video analysis whenever possible. Conservation of Momentum is one of the rare times the photo gates are a good choice. Video analysis would be time-consuming for the number of collisions we need to run.
