Fun With Vectors and Scale Diagrams

We started class today by reviewing  collinear vector addition, then proceeded to learn the "Tail to Tip" Method of vector addition. We used this method to add non-collinear vectors, which we are unable to add algabraically. The steps to create one of these wonderful diagrams include:

1. Write your scale and reference coordinates
2. Start by marking an "X"
3. Place your first vector's tail at the "X" (Remember to label it with the magnitude AND direction!)
4. Draw the next vector, starting at the tip (the arrow head) of the last vector. Continue to repeat this process with the rest of your vectors.
5. Draw a dotted line from the "X" to the tip of your final vector. This dotted line represents the Resultant Vector.
6. Use a ruler to measure the resultant vector. Determine its direction from the starting point ("X") using a protractor.

After taking notes, we practiced adding non-collinear vectors until the class ended.
