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!
