Physics 3-5-19 Bernoulli

PHYSICS: Were you amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!

Today we concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. Tomorrow we’ll take a look at the problems and a couple more cool ways to apply Bernoulli!!

Physics 2-21-19 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.

Oh, and here’s the lecture on Pascal’s law and hydraulics and the like.

Physics 2-26-19 Archimedes’ Principle

PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 From Tuesday – 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 2-12-19 Angular Momentum & Newton’s Law of Universal Gravitation, Pt. 1

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 formulas, also make sure you can apply the concepts.

Ready to escape? We’ll tackle the rest of the applications of this law tomorrow!

Physics 2-11-19 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 2-8-19 Vertical Circular Motion

PHYSICS: Great job on the vertical circular motion problems! Here’s the short lesson from today, then a look ahead at some of the upcoming circular motion problems. Fun times!! 🙂

HOMEWORK UPDATE: Add to the Circular Motion WS 2, these from the book – Pg. 264, 1 – 7, 10, 11.
