How do you add two parallel vectors?

This tutorial will give a you a nice trick for adding up vectors that point in exactly the same direction.

Summary

  1. When adding parallel vectors, the new vector is in the same direction and the total length is just the sum of the vector lengths

Notes

    1. Connecting vectors tail to tip is like following a set of directions
    1. Connect the tail of the 5 vector to the tip of the 15 vector
    2. Start at the tail of the 15 vector
    3. End at the tip of the 5 vector
