1A40.10 - Vector Demos

Code Number:
1A40.10
Demo Title:
Vector Demos
Condition:
Fair
Principle:
Vector Addition, Resultant Vector
Area of Study:
Mechanics
Equipment:
Vector demo, Metal Globe, Plexiglas 1/2 Sphere, Globe Stand, Magnetic Radial Vectors, and A Few Small Button Magnets.
Procedure:

The large vector demo is 80 cm X 110 cm.  Loosen the set screw that holds the diagonal and position the demo in any configuration desired.  Note that the diagonal is labeled every 20 cm.

No advanced preparation needed. The globe and magnetic orange rays are for showing radial vectors. The rays will stick directly onto the metal globe. On the Plexiglas 1/2 sphere you will need to put one of the small button magnets on the inner surface of the sphere to hold the vector on.
