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.

Physics 1-11-19 Collision Homework

PHYSICS: Here’s a new way to study collisions! Somebody’s having way too much fun with veggies!

How are you doing with last night’s homework? Here’s our look at some of the conceptual questions and a look at setting up some of the homework.

Are you ready to crank it up a bit? Here’s a hint – check for connections between the conservation of momentum and the conservation of energy. You can do it!
