Physics 1-9-18 Collisions, Pt. 2 & Bouncing

PHYSICS: Collisions – they’re all around us and they all obey the law of conservation of momentum. Great job on setting up the problems in class today – now on to working them tonight! Check for connections between the conservation of momentum and the conservation of energy. 🙂

Oh – and watch out for flying ping pong balls!!

Hon Chemistry 1-9-18 Wave Properties of Light

HON CHEMISTRY: Isn’t this a super cool picture of light? So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves?

How’d you like the light problems so far? I forgot to hit “resume recording” after I paused, I’m posting a lecture from last year. We’ll resume with the photoelectric effect tomorrow!
