Physics – Waves (for 3/30 – 4/3/20)

PHYSICS: Hey guys! Here’s our discussion on the properties of waves. 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!

And while you’re here, click here for the next video – NASA Launchpad: Wave Motion. Since we’re not going to be able to play with slinkies in person, this will be a good replacement!

Physics – Simple Harmonic Motion (for 3/23 – 30/20)

PHYSICS: Springs and pendulums, back and forth… back and forth. Here are the two lectures for this week for simple harmonic motion. The first vodcast we’ll concentrate on springs, in the second, we’ll concentration on pendulums. Wonder how this could be used to solve a design challenge? Hmmmm…..

Physics 3-18-20 Paper Airplanes & Physics

PHYSICS: Welcome back! I’ve missed you guys!! This new way of learning is going to be a tad awkward for a while, but remember how you eat an elephant…! We’ll gradually build and add new aspects to what we do – lessons via vodcasts and hopefully very soon, video conferencing with the class. For now, though, baby steps! Be sure and explore the Remote Learning Page in your Honors Physics page in PowerSchool.

So what do you remember about Bernoulli? And lift? Use the thLAB: Paper Airplanes & Physics on the class website (and the Internet, You Tube, etc.) as a review and design your own, best paper airplane.

Next, build and test at least two different types of planes. Record the pertinent data and make a video of your longest flight. Then, go to the Discussion Board in PowerSchool Learning and enter the following:

  1. Your longest flight time
  2. Your longest flight distance
  3. Photo of your two (or more) best airplanes. (Let me know if you can’t do this in the Discussion Board. We may have to move this part to Google Drive. For now, it’s a way for me to see what the Discussion Board is capable of allowing.)

Finally, upload a VIDEO of your longest flight to your Shared folder. Save as P5 Last Name, First Name Paper Airplane Physics Video

Today is going to be a great day!!

Physics 3-2-20 Bernoulli UPDATED

PHYSICS: The Bernoulli can explain so much! Great job with the concepts today. Now take them and your new formulas and go back and tackle those problems from Friday! Remember the concepts that are behind the formulas!

UPDATE: Here’s a reboot of the fluid motion Bernoulli lectures – part 1 and part 2 from last year. These have all the info that didn’t make it to this year’s vodcasts.

Also, here’s Julius Sumner Miller Bernoulli video on YouTube if you missed him in class!

Fluid Motion & Bernoulli, Part 1

Bernoulli, Part 2

Physics 2-24-20 Pascal’s Law

PHYSICS: Did you realize that fluids could produce that much force? Make’s you wonder at the awesome way God designed those beautiful under water sea creatures to withstand so much pressure, doesn’t it? This little creature is a lionfish from the waters of Lembeh, Indonesia.

Missed you guys today! Here’s the lecture on Pascal’s law and hydraulics and the like.

Physics 2-19-20 Archimedes’ Principle

PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 From Wednesday – Archimedes’ Principle.

Great topic for investigation! Speaking of which – what did you find? When the kid jumped out of the boat, did the water level rise, fall, or stay the same? Hmmmm…..

Physics 2-11-20 Newton’s Law of Universal Gravitation

PHYSICS: Wait! There’s a fourth law? Yep – Newton’s law of universal gravitation! So when you jump off of something, the Earth moves, huh?

You’ve learned little g, now you know big G! Good job setting up the problems, also make sure you can apply the concepts.

Ready to escape? 🙂

Physics 2-10-20 Rotational Dynamics

PHYSICS – Wow! Could you do this? Here’s the lecture on rotational inertia, angular velocity, and angular momentum – rotational dynamics! We’ll pick up the conservation of angular momentum tomorrow. Fun times!

By the way – I wonder how all this applies to other rotating things…like maybe the Earth? Hmmmmm……
