The wheel's axle is then placed horizontally and the free end of the axle processes about the supported end. </p><p>The gyroscope seems to defy gravity because the torque created by the spinning wheel counteracts the torque due to gravity.

Gyroscopes have been used through history for varied uses such as stabilizing spacecraft or for guidance systems on ships and missiles.</p> 89 tag:techtv.mit.edu,:Array/219169280 2008-06-16 00:45:16 -0400 wrenow MIT Physics lecture demonstration:<br />DYNAMICS - Conservation of Angular Momentum<br />The demonstrator sits on a rotating stool and holds a spinning bicycle wheel equipped with handles on each end of its axle. The wheel is held in a vertical plane passing through the axis of the stool. If the spinning wheel is turned into a horizontal plane, the stool will rotate in the opposite sense to the spin of the wheel. 66 tag:techtv.mit.edu,:Array/219147160 2009-02-24 15:27:06 -0500 Blended Learning Open Source Science or Math Studies (BLOSSOMS) BLOSSOMS-Ice Skater's Delight: The Conservation of Angular Momentum with Professor Walter Lewin 1375 tag:techtv.mit.edu,:Array/219123860 2009-06-10 14:04:53 -0400 MIT Department of Physics Technical Services Group Two pucks of the same mass are slid at each other on an air table, and their resulting collisions demonstrate conservation of momentum. Notice on the first collision, for example, that when a moving puck hits a stationary puck dead-on, that the second puck leaves with the same velocity as the first, and the first puck stops moving completely. 80
