PURPOSE: To demonstrate properties of vectors.
DESCRIPTION: Various lengths of magnetic vectors can be affixed in arbitrary positions to a magnetic board. The lengths of the three longer vectors are in the ratio 3:4:5, so that they can form a right triangle. Illustrate vector addition, subtraction, motion of vectors, and commutative properties.
SUGGESTIONS: DANGER: Remove vectors before moving boards. For classrooms use the portable version, A2-21.
REFERENCES: (PIRA 1A40.40)
EQUIPMENT: Collection of magnetic vectors.
SETUP TIME: None.
