Introduction to Free-Fall and the Acceleration due to Gravity
In this lesson we extend our knowledge of Uniformly Accelerated Motion to include freely falling objects. We talk about what Free-Fall means, how to work with it and how to identify and object in Free-Fall. Today I get to introduce so...

Conservation of Energy: Free Fall, Springs, and Pendulums
The energy of a closed system is always conserved. This is an important law of physics! But energy does change forms. What are all the forms and how do they interchange? You gotta watch this clip to find out, buddy!

Newton's Law of Universal Gravitation
You thought we were all done with Newton, didn't you? You figured that three laws are enough for any scientist. Well think again! Newton was quite the champ, and his work with gravity was revolutionary. I mean, the guy invented calculus...
