# Geometry - Vectors

Suppose that something is moving and we want to try to understand what that movement is. There are two basic pieces of information that we have to know. We have to know what direction is the object moving, and how fast. Those two pieces of information can be linked together to form what we think of as a vector. A vector is a visual manifestation of movement.

In today's free Geometry video on vectors, you'll learn how to name a vector using component form, which lists the horizontal and vertical change from initial point to terminal point. Then Professor Burger covers finding the Magnitude of a Vector using the Distance Formula and then you'll bring in your knowledge of right triangles to figure the direction of the vector. This video contains plenty of examples to get you comfortable with the concept of vectors. The fourth lecture covers equal vectors, which are two vectors that have the same magnitude and the same direction. It also covers parallel vectors, which are vectors that have the same direction or possibly opposite direction. Unlike equal vectors, though, parallel vectors may have different magnitudes.
