Physics 1-13-17 Collision Problems & Bouncing

Posted on by

PHYSICS: Here’s a new way to study collisions! Somebody’s having way too much fun with veggies!

How are you doing with the problems? Since we didn’t really work any in class today, I’ve found an old vodcast that I’ve posted below that also has some of last night’s kinetic energy problems as well as the lesson on bouncing, etc.

Are you ready to crank it up a bit? Here’s a hint – check for connections between the conservation of momentum and the conservation of energy. Also, that old vodcast below might have some hints for you! You can do it!

Chemistry 1-13-17 Intro to Radioactivity

CHEMISTRY: Great start to a new chapter! I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. Also now you know where E=mc2 came from!!

By the way, you ought to read about the life of Marie Cure when you get a chance. Fascinating woman of science with an incredible story!

Hon Chemistry 1-13-17 Bohr Model of the Atom

HON CHEMISTRY: I figured anybody who ditched his honeymoon to finalize his work on atomic theory deserved to have his picture on our website. (And, by the way, great job making like electrons today – way to role play!)

Here are a couple of other links to some great video clip that begin to show the connection between our lab on spectroscopy, the hydrogen emission spectrum, and how we can identify elements. They’ll be very helpful as you study!! Spectrum of the Stars, The Emission Spectrum of Hydrogen
