A physical pendulum finds stability in its inverted position when driven at the proper frequency and amplitude combination.
The physical pendulum is a 45 cm x 2 cm x 6 mm (1/4") strip mounted on a ball-bearing pivot and can rotate 360 degrees...
Push-me/pull-me gliders or pendulum glider on air track.
The center of gravity fixed in (or outside) the object always orients itself with minimum potential energy on a vertical line below the support point. When an irregular shape is thrown into the...
Irregular lamina with marked center-of-mass tossed in air.
The center of gravity fixed in (or outside) the object always orients itself with minimum potential energy on a vertical line below the support point. When an irregular shape is...
What it shows: Two bodies, rotating about each other, rotate about their common center-of-mass (COM). The COM exhibits uniform motion (or none at all) regardless of what the two bodies are doing.
How it works: The "bodies" are 4-1/2" diameter acrylic...
