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

Season 1 Episode 9 | 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!

Extras
Shini introduces the idea of Quantum Mechanics and how it helps us understand light.
Why is e=mc2 such a big deal? And what about this grumpy cat in a box and probability?
Let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it useful?
We've all heard of relativity, but what is it? How does it relate to light and motion?
Getting power at home is pretty amazing – and much more complicated than it may seem.
We've talked about how AC circuits change voltage, but let's take a deeper look.
Sunlight, moonlight, torchlight... They all work the same. Let's talk about light!
Light's behavior seems counterintuitive. That is, until you figure out light is a wave.
We've learned about light and how to bend it to our will. But what can we LEARN from it?
Maxwell's Equations tell us a lot about electromagnetic interactions and physics.
