Physics Chapter 4 • Working With Vectors Adding vectors: A B 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. B A A+B Adding vectors: A+B+C A B C Draw the first vector listed. Then draw the second vector, placing the tail on the head of the first one. B A C Repeat with the next one. A+B+C Then draw a line from the tail of the first to the head of the last. This can be done with many vectors! Adding vectors: A+B+C+D+E C A D B E A+B+C+D+E B A C D E Subtracting vectors: A B 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. -B A A-B Adding vectors: A B 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. B -A B-A What do you notice about these two? A B B A -A B–A -B A–B What do you notice about these two? A B B A A+B B+A A B Multiplying vectors: 3A and -2 B A B 3A -2B 3A – 2B A B -2B 3A 3A – 2B
