From Vectors and 2D Motion: Crash Course Physics #4 Episode 4 | 10m 5sVideo has Closed Captions| CC Today we continue on our journey of understanding motion, direction, and velocity.

Combining Vectors Graphically: Students learn to combine component vectors graphically to produce resultants and use the head-to-tail method to do a vector analysis of a route between rooms.

Vectors have units, if you leave them off you are probably a mathematician (just kidding). Also, this notation can be expanded to three dimensions by adding a z-hat or k-hat component.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

But what if the two vectors are not in the same direction and they are not perpendicular? Well, here is the key to vector addition: Every vector can be broken into two vectors.
