Universal Gravitation Video!

This is a video that gives a quick explanation of universal gravitation, as well as a couple practice problems. Excuse my sickly voice. Note: The radius of Earth should have been squared at 7:13.

Gravity

Dr. Ryan Stone (Sandra Bullock) is a brilliant medical engineer on her first shuttle mission, with veteran astronaut Matt Kowalski (George Clooney) in command of his last flight before retiring. But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone and Kowalsky completely alone - tethered to nothing but each other and spiraling out into the blackness.
