SBEC Chemistry and Physics http://tskinnersbec.edublogs.org Use what talents you possess, for the woods would be silent if no birds sang except for the best. - Henry van Dyke Sat, 07 Nov 2009 04:12:34 +0000 http://wordpress.org/?v=2.8.2 en hourly 1 Physics 11-6-09 Potential Energy & the Law of Conservation of Energy http://tskinnersbec.edublogs.org/2009/11/06/physics-11-6-09-potential-energy-the-law-of-conservation-of-energy/ http://tskinnersbec.edublogs.org/2009/11/06/physics-11-6-09-potential-energy-the-law-of-conservation-of-energy/#comments Sat, 07 Nov 2009 04:12:34 +0000 Ms. Skinner http://tskinnersbec.edublogs.org/?p=1175 PHYSICS: So why is the first hill of a roller coaster always the highest? Here’s the lecture from Tuesday on potential energy and the conservation of energy. Thanks for trusting me, Arthur! :)

See, it wasn’t so bad – orbital notation, I mean. :) You can do it! Don’t forget to use the Aufbau Principle! Homework for Friday night is to finish Wednesday’s questions, if you haven’t already, and to do Thursday’s questions. Have a great extra long weekend!

Here’s the lecture from today on the photoelectric effect. How’d you like the field trip? What are some other applications of the photoelectric effect?

I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

You set up the structure, we’ll put in electrons tomorrow. Don’t worry, it’s supposed to be a little strange, you’ve never heard of this before, right? We’ll go slow again tomorrow and you’ll get it, I promise! :)
