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: Here’s our overview of the sound chapter – and a short look at the speed of sound lab at the end. God bless you as you study! You’ve got this!!

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics and beats.
Speaking of discussion – what about the Tacoma Narrows Bridge? Could we add on to our explanation? Here’s a link, if you’d like to see it again: Tacoma Narrows Bridge
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!!
Here’s the link to the video we watched today on shock waves, supersonic flight and sonic booms: Supersonic Flight & Sonic Booms
PHYSICS: Our discussion of pendulums seems to have disappeared, so here are a few old vodcasts on simple harmonic motion that might help. The first vodcast below concentrates on spring. The second concentrates on pendulums. The third is a look at an old spring problem.

PHYSICS: Here’s the vodcast on the properties of waves and the a link to the NASA video on wave motion for Tuesday. 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!
Here’s the link to the NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion. Since we’re not going to be able to play with slinkies today in person, this will be a good replacement!
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: Great review today! Here’s a last look at some of the concepts and problems from chapter 8.
By the way, if you’re interested, after you left, I did a bit more work with #33 after you left. Just some ideas for thought.
PHYSICS: Great job setting up the Bernoulli problems today. My best hint – Remember the concepts behind the formulas you want to use!!
