## AP Physics 1: Vectors - Chapter Summary and Learning Objectives

In order to gain a satisfactory understanding of physics, it's essential that you understand vectors. In this series of video lessons, a qualified instructor will walk you through the definitions of different kinds of vectors and how to describe them in terms of magnitude, direction and other qualities. You'll also learn how to perform calculations on those vectors, including scalar multiplication. In these lessons, you'll learn things like:

- The definition of a vector
- Geometric methods for for adding and subtracting vectors
- How to calculate characteristics of vectors

Video | Objective |
