WEIGHTED FRISBEE
APPARATUS
weighted frisbee with flashlight
bulbs
202-15-E2
foam rubber landing pad
202-01-A
DESCRIPTION
Off-center weighted frisbee has two
flashlight
bulbs, one at its geometric center and the other at its center of
mass.
The bulbs can be switched on independently. Toss frisbee in the
air
with bulb at center lit to show that the angular velocity remains
constant
even while the linear velocity changes. Use the other bulb to
show
that the center of mass follows a parabolic path regardless of the
rotation
of the frisbee.
NOTES
Have someone catch the frisbee, or
let it
fall on the foam rubber pad, so that it isn't damaged by hitting the
ground.
Frisbee takes two AA batteries,
inserted so
that both positive ends point toward the rim.
