DESCRIPTION
An off-center weighted frisbee
has two LEDs, a white one at its geometric center and a green
one at its center of mass. The LEDs can be switched on
independently. Toss the frisbee up in the air with the
LED at the center of mass turned on to show that it follows a
parabolic path regardless of the rotation of the
frisbee. Use the other LED to show that the angular
velocity remains constant even while the linear velocity
changes.
NOTES
The frisbee requires two CR 2032
batteries. It has jumpers in place of on/off switches.
