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……

Physics 1-24-20 Stability & Torque Problems Review

PHYSICS: Ohhhhhhhhh….so that’s how they can walk across that line! Wait – why do they keep moving their bodies?? Great opportunities for discussion and application!?!

Here’s the discussion from today on how stability relates to center of mass. At the beginning, a quick look at a couple of torque problems from the homework, Torque Worksheet 2.
