All things physics! Vodcasts for physics lectures and homework review.
PHYSICS: Can you believe it?!? This is your LAST web post comment!! This is where you put it and here are the three things I want you to talk about:
1) How did physics grow you? What did you learn about yourself?
2) What advice do you have for future physics students?
3) What could we have done different this year that would have helped you learn physics better?
Can’t wait to hear from you!! 🙂
PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics. (Plus another lesson on beats at the end.)
PHYSICS: All kinds of ways to make music! And great discussion of intensity and resonance! Were you okay with the problems?
Couple of items to apply for further contemplation – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion!
PHYSICS: So you can see sound?! Here’s the lecture from today – some wave stuff, echolocation, speed of sound, …. Too much fun!!
Also, here’s the link to the video we watched today on shock waves, supersonic flight and sonic booms: Supersonic Flight & Sonic Booms
PHYSICS: Cool thing, standing waves! Can you think of some applications of constructive and destructive interference?

PHYSICS: Today’s lesson is three parts. First you’ll watch a short vodcast on the properties of waves and then a short NASA video on wave motion (link is below) since we won’t be able to place with slinkies today in person. To wrap it up and make sure you have the concepts nailed down, there are three activities from the The Physics Classroom that you’ll do.
1) Vodcast – view below
2) NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion.
3) Either your book HW for tonight or The Physics Classroom Activities – Concept Builders: Wave Basics, Wave Cases and Concept Checkers: Simple Wave Simulator (either mode is okay)
Do you remember anything from your earlier 8th grade physical science days? Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf). Easy peasy – and don’t forget the applications!
PHYSICS – Here’s our very short look at simple harmonic motion and pendulums. Now head off and start playing with the pendulum simulation.
PHYSICS: So what do you reckon is the spring constant of a trampoline spring? Here’s our discussion from Friday on simple harmonic motion and springs.
Did you figure out what was wrong with that problem? 😉

PHYSICS: Good review today, but the microphone didn’t cooperate, so I’ve found an old review that’s also good and includes the things we talked about today, for example – the hollow sphere problem. I’m just saying. So here’s a last look at some of the concepts and problems from chapter 8 from last year. And don’t forget about lift!
Below the lesson for today is the help session from this morning – #5 and #6 on the Bernoulli God bless you as you prepare!
Monday Morning Help Session, Bernoulli WS #5 & #6
PHYSICS: Great job setting up the Bernoulli problems today. My best hint – Remember the concepts behind the formulas you want to use!!
