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.

REFERENCES:

EQUIPMENT: Collection of magnetic vectors.
