00:00This machine is called an overbalanced wheel.
00:03It looks like a wheel with small weights attached to it.
00:06What's the idea?
00:07The idea is very simple.
00:09When the wheel turns, the weights on.
00:12One side move outward, giving more force.
00:15On the other side, the weights move inward, giving less force.
00:19Because of this difference, the wheel looks like it can keep spinning on its own.
00:24But does it really work?
00:26Not really.
00:27It may spin for some time, but it cannot run forever.
00:31Friction and air resistance slowly stop it.
00:34So this is not a free energy or perpetual motion machine.
00:38What is it used for?
00:39To teach basic physics.
00:41To show how gravity and torque work.
00:44To explain why perpetual motion is impossible.
