  • HANK: SoPhysics. Uh, right. Physics, physics, physics, physicsare you getting all this?

  • We have been talking about doing Crash Course Physics for a long, long, longlonglong time.

  • Youve wanted it, weve wanted to do it, and now thanks to our friends at PBS Digital Studios, were doing it.

  • There’s just one thing. I’m hosting Crash Course Philosophy.

  • But I do know someone super-qualified for the job.

  • SHINI: Hi!

  • HANK: Hi. This is our host for Crash Course Physics.

  • Me? I’m gonna go have a corndog and host Philosophy. Take it away, Shini!

  • SHINI: I’m Dr. Shini Somara, a mechanical engineer and fluid dynamicist by qualification.

  • For the last few years I've been hosting science and tech shows on TV,

  • like TechKnow, Tomorrow's Food, and The Health Show.

  • Wanna know more about me? There are links in the dooblydoo.

  • So... let’s talk Physics! I love physics and chances are you do too, even if you don’t know it yet.

  • So I’m really excited to host this series of Crash Course. In this series, well

  • be covering AP Physics 1 & 2, mostly. But well also have a little time for other things along the way.

  • Everything you do, build, or say will be governed by physics, so wouldn’t it be nice to read

  • the rule book? A rule book that will help you through life. Physics is elegant.

  • It’s also practical and fun. Understanding time, position, velocity, and acceleration

  • and how they all work together can help you understand your place in the universe -- literally!

  • And I’m sure youve heard of Newton’s Laws, like his first law: An object in motion

  • will remain in motion, and an object at rest will remain at rest, unless acted upon by a force.

  • But what does that mean? And what does it have to do with acceleration?

  • And what are vectors? Scalars? And what does this mean?

  • Kinetic Friction and Static Friction? What’s the difference?

  • Well explain all of that. But what’s more special is getting to figure out why

  • understanding these things is so valuable. Understanding how the world, the universe,

  • works gives us a richer and more immersive experience in life. It gives us the opportunity

  • to see the beauty in nature in vast and unexpected ways.

  • Now a lot of people think physics is hard, but it's easy!

  • Well, it’s as easy as we can make it.

  • So join me, Dr. Shini Somara, this year on Crash Course Physics which is produced in

  • association with our good friends at PBS Digital Studios.

HANK: SoPhysics. Uh, right. Physics, physics, physics, physicsare you getting all this?
