2016.10.10: "In college to become a Physicist, and you are my physics teacher (I gave up on the one I am paying tuition for a month ago). ... Hidden gem of physics videos, I watch you and Prof Walter Lewin side by side. Why can't physics be taught in the classroom as a source of joy, like it is meant to be, and as you clearly do? Anyway, you are helping me marry my love of pure math to the applied math that is physics ;) ... You helped me work through my lab problems which weren't explained by my teacher or book! You, sir, are a living contradiction to charges that videos can't really teach. I stop the video and work the problem ahead of your student-clones, and it helped me watch for pitfalls and truly understand what I was doing, not just plug numbers into formulas. Thank you!"

Introductory Conservation of Momentum Explosion Problem Demonstration (5:39)
Now that we have learned about conservation of momentum, let’s apply what we have learned to an “explosion”. Okay, it’s really just the nerd-a-pult launching a ball while on momentum carts. This is an AP Physics 1 Topic.
