Matt, I'm just throwing in all of the notes, we can simplify this later on
Plenty of measurements in physics require both magnitude and direction to be accounted for. These are called vectors, and are represented as arrows.
Changes in an object's location or position over a period of time. Several measurements in motion are vectors:
- Displacement (from starting to destination point)
- Velocity (speed with direction)
- Acceleration (how quickly does the velocity change?)
