  1. Physics • Working With Vectors Chapter 4

  2. Adding vectors: A + B A B B A A + B Draw the first vector listed. Then draw the second vector, placing the tail on the head of the first one. Then draw a line from the tail of the first to the head of the last.

  3. Adding vectors: A + B + C A B C B A C A + B + C This can be done with many vectors! Draw the first vector listed. Then draw the second vector, placing the tail on the head of the first one. Repeat with the next one. Then draw a line from the tail of the first to the head of the last.

  4. Adding vectors: A + B + C + D + E C D E A B E A+B+C+D+E B A C D

  5. Subtracting vectors: A - B A B -B A A - B Draw the first vector listed. Then draw the second vector reversed, placing what was the tail on the head of the first one. Then draw a line from the tail of the first to the head of the last.

  6. Adding vectors: B - A A B B -A B - A Draw the first vector listed. Then draw the second vector, placing the tail on the head of the first one. Then draw a line from the tail of the first to the head of the last.

  7. What do you notice about these two? A B B A -A - B B – A A – B

  8. What do you notice about these two? A B B A A + B B + A A B
