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: This board is for use in classrooms; blackboards provide magnetic base in lecture halls (Demonstration A2-22).
REFERENCES: (PIRA 1A40.40)
EQUIPMENT: Portable vector board with collection of magnetic vectors.
SETUP TIME: None.
