Friction: Crash Course Physics #6

S1 E6 / 10m 27s
Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it started moving? You might think it's all about weight, but actually it's about friction. Two kinds of friction! Today, Shini tells us about Static and Kinetic friction; how they work and how they're different.

Newton's Laws: Crash Course Physics #5

S1 E5 / 11m 3s
I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

Vectors and 2D Motion: Crash Course Physics #4

S1 E4 / 10m 5s
Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of Vectors and Scalars so we can better understand how to figure out motion in 2 Dimensions. But what does that have to do with baseball? Or two baseballs?

Integrals: Crash Course Physics #3

S1 E3 / 10m 8s
Continuing with last week's introduction of calculus, Shini leads us through the ways that integrals can help us figure out things like distance when we have several other key bits of information. Say, for instance, you wanted to know how far your window was off the ground. By using integrals, a tennis ball, and a stop watch, you can figure that out!

Derivatives: Crash Course Physics #2

S1 E2 / 10m 1s
CALCULUS! Today we take our first steps into the language of Physics; mathematics. Every branch of science has its own way to describe the things that it investigates. And, with Physics, that's math. In this episode, Shini talks us through derivatives and how calculus helps us to understand the world around us.
