This video demonstrates conservation of angular momentum. When a person on a rotatable platform (initially at rest) tilts the axis of a rotating bicycle wheel, conservation of angular momentum results in spinning of the...
This video demonstrates the conservation of angular momentum. In the experiment, as weights are pulled closer to the axis of rotation, a person on a rotating platform will spin faster due to a change in the moment of...
This video shows a demonstration of buoyancy. A small glass vessel with a hole in the bottom is partially filled with water and placed in a partially filled cylinder of water. The cylinder has a rubber diaphragm which,...
This video demonstrates that a ping pong ball can "float" on a stream of air. The air rushing around the ball creates a pressure low enough to lift and support the ball, even when the ball is not directly over the air...
