Newtonian Gravity: Crash Course Physics #8
I'm sure you've all heard about Isaac Newton and that apple that fell on his head and how that was a huge deal to our understanding of gravity. Well... let's talk about that. In this episode...
==========
When people say that Isaac Newton completely transformed the field of physics, they really aren't kidding. Now, we’ve already talked about his three laws of motion, which we use to describe how things move. But another of Newton’s famous contributions to physics was his understanding of gravity. When Newton was first starting out, scientists’ concept of gravity was pretty much nonexistent. I mean, they knew that when you dropped something, it fell to the ground, and from careful observation, they knew that planets and moons orbited in a particular way. What they didn’t know was that those two concepts were connected. Of course, just like with motion, we now know that there’s a lot more to gravity than what Newton was able to observe. Even so, ...
