Scalars, Vectors, and Vector Operations

What are all these funny little arrows? They're vectors! And we will use them to represent every single force we discuss in physics, so we need to know how to draw them, add them, subtract them, split them up into X and Y components, the whole nine yards. We also need to know the difference between vectors and scalars. So let's get this stuff taken care of before we dive into the physics!

If I had math and physics teachers like you in high school, I might not have majored in literature.

This guy deserves more views. I've gone back to University after teaching ESOL overseas for 10 years, and COMPLETELY lost in physics coz they teach like we remember all the basics out of highschool. This is so simple and easy to understand, and thorough (for such a basic overview style). Cheers mate, I'll turn my addblock off on your vids.

I'm a college freshman student and I'm about to take the very first physics course in my life. I never took physics in high school and I dropped math eventually. I was thankfully able to understand the differences between vectors and scalars from this video, as well as trigonometry. Calculating vector components sounds a bit complicated to me though. I still have an interest in astronomy and physics, and this channel is helping me understand the main concepts of my classical physics class. Just currently praying that this class won't end up in disaster for me. Thanks Dave.

In the boat example, it depends whether you want to cross as fast as possible or to take the shortest path from bank to bank. If the latter, then you should point the boat upstream and the result would be sqrt(15) m/s and zero degrees.
