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

When I say “work,” what’s the first thing that comes to mind? Maybe a cubicle? Or a briefcase? Or that history exam that’s coming up soon? But if you’re a physicist, work has a very specific meaning -- one that has very little to do with spreadsheets or the fall of the Roman Empire. Today, we’re going to explore that definition -- and how it connects to one of the most important principles in physics: conservation of energy. We’ll also learn what physicists mean when they talk about another concept that comes up a lot in daily life: power. So let’s get to…work. [Theme Music] So far in this course, we’ve spent most of our time talking about forces, and the way they make things move. And you need to understand forces before you can underst...
