Astrophysics and Cosmology: Crash Course Physics #46

9m 15s

In this episode of Crash Course Physics, Shini sits down to talk about Astrophysics and Cosmology. By using what we've learned this year, we can come to understandings about our universe. Understandings that open ideas to us to help us grasp how our universe works. Join us for this final episode of Crash Course Physics as we head into the final frontier.

Episodes

  • Collisions: Crash Course Physics #10: asset-mezzanine-16x9

    Collisions: Crash Course Physics #10

    S1 E10 - 9m 20s

    COLLISIONS! A big part of physics is understanding collisions and how they're not all the same. Mass, momentum, and many other things dictate how collisions can be unique.

  • Work, Energy, and Power: Crash Course Physics #9: asset-mezzanine-16x9

    Work, Energy, and Power: Crash Course Physics #9

    S1 E9 - 9m 54s

    When you hear the word, "Work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to walk us through it. Also, Energy and Power!

  • Newtonian Gravity: Crash Course Physics #8: asset-mezzanine-16x9

    Newtonian Gravity: Crash Course Physics #8

    S1 E8 - 9m 18s

    In this episode of Crash Course Physics, Shini sits down to talk about the realities of the apple story and how Newtonian Gravity is more than a little important.

  • Friction: Crash Course Physics #6: asset-mezzanine-16x9

    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: asset-mezzanine-16x9

    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: asset-mezzanine-16x9

    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: asset-mezzanine-16x9

    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: asset-mezzanine-16x9

    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.

  • Motion in a Straight Line: Crash Course Physics #1: asset-mezzanine-16x9

    Motion in a Straight Line: Crash Course Physics #1

    S1 E1 - 10m 39s

    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, and the definition of acceleration.
