It’s everywhere, and yet nowhere. You find it on Earth, but not in the dead of space. Yet it keeps you from floating into space. This is the power of gravity. Join us as we explore gravity in all of its elements. 9. What Is Gravity? So what exactly is gravity? I’m sure you have

This is a water jet pack… but no, that’s not me flying it. This is me. It’s harder than it looks, ok? But to understand how it works, we need to first talk rocket science. Rocket science is meant to be one of the most complicated things in the world, but the basic principle is

Acceleration is one of the most important concepts in physics. Understanding it allows a firm grip on the deepest law of mechanics, Newton’s Second Law of Motion, F=ma. This is big: Acceleration HAS to be clear! But acceleration is tricky. The trickiness is evident upon realizing that an object’s acceleration has NOTHING to do with

Hey it’s professor Dave, let’s talk about special relativity. Remember before how we said that the Newtonian paradigm breaks down in the realm of the very small and the very fast? We learned about quantum mechanics for the small, but what about the fast? To answer this, let’s recall that in classical physics we learned
