Under bright lights you can see the coupled oscillation of the carts back and forth, but under black lights you can see that the center of mass moves at a constant velocity. 103 tag:techtv.mit.edu,:Array/185499340 2008-08-27 16:48:12 -0400 MIT Department of Physics Technical Services Group <p>A bicycle wheel is suspended from one of end of its axie by a rope, and spun up by hand. 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/185459780 2008-08-28 11:45:13 -0400 MIT Department of Physics Technical Services Group <p>A string carrying two weights is hung over a low friction bearing mounted pulley. The weights have slightly different masses, causing a uniform acceleration. When the time it takes the weights to move 1 meter is timed, we can calculate the acceleration of the system due to gravity. Because of the low amount of friction in the system, this value is very close to the theoretical value.</p><p>Read more about the <a href="http://en.wikipedia.org/wiki/Atwood_machine">Atwood Machine</a>. </p> 46 tag:techtv.mit.edu,:Array/185433800 2008-10-23 12:54:41 -0400 RLE Professor Collin M.
