 ===== Description =====
-Precession
+A couple glass spinning tops are available in the demo room. These spinning tops are quite small, about 2.5cm in diameter.
-precession, angular momentum
-Can be found in the yellow cupboard next to the box of balls
-Updated on: 06/13/13
 ===== Purpose =====
+To demonstrate the effect of gyroscopic precession on the motion of spinning tops.
-To demonstrate the precessional effects of a spinning top.
 ===== Apparatus =====
+  * Spinning top
-Two glass tops, overhead projector
 ===== Setup =====
+Simply hand-spin the tops. The angular velocity of precession of a top is independent of the angle of slope of the axis of the top and while the top maintains speed this can be shown. As the top straightens up the angular velocity of precession remains constant.  As speed of rotation falls away the angular velocity of precession increases and this can also be shown.
