Q: Is a top a toy designed to spin rapidly on the ground? ¶
A: Yes, and the motion of which causes it to remain precisely balanced on its tip because of its rotational inertia.
Q: Is a top one of the oldest recognizable toys found on archaeological sites? ¶
Q: Were tops constructed of wood? ¶
A: Yes, and sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion.
Q: Are tops featured in National Championships in Chico? ¶
A: Yes, and California and in the World Championships in Orlando, Florida.
Q: Is a top produced in the most simple forms by twirling the stem using the fingers? ¶
Q: Are tops spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger? ¶
Q: Is a top described by equations of rigid body dynamics? ¶
A: Yes, Typically the top will at first wobble until the shape of the tip and its interaction with the surface force it upright; contrary to what is sometimes assumed, longstanding scientific studies show that less friction increases the time before the upright position is reached. After spinning upright for an extended period, the angular momentum will gradually lessen , leading to ever increasing precession, finally causing the top to topple in a frequently violent last thrash.
