Motion in a straight line a fast as possible by Dr. shini somara
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 -- and maybe even know enough to dispute it -- you have to know the science of motion, too. And in order to do that, you’ll need to understand a few essential conditions that describe your physical place in the universe. Conditions like time, p
