Motion in a Straight Line: Crash Course Physics #1
In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity,...

Hi, I’m Dr. Shini Somara and I hear you want to learn physics. I have to say: good choice. Physics is the science of how the world -- really the whole universe -- works. And I don’t know if you’ve noticed, but in the world I live in, things tend to move around a lot. So that’s what we’re going to study first: the science of motion. And it turns out to be incredibly useful -- for figuring out things like where you are, or where you’ve been, or how you’re moving through the world. Why is that worth knowing? Well, for one thing: The police use physics to decide how exactly how fast you’re moving through the world, and if that motion happens to break the law. So if you’re gonna understand how and why you got that ticket they gave you -- ...
