Question
A top is set spinning so that the rotation is counterclockwise around its axis when viewed from above. When the top is placed on a level surface it happens that its axis of rotation is not quite vertical. Viewed from above, which way does the rotational axis of the top precess?a. clockwise
b. counterclockwise
c. It's random, if it starts clockwise, and vice versa, i.e., a 50% chance either way.
d. The direction depends on the little shove given to the axis when the top is placed on the surface.
e. In the northern hemisphere it will be clockwise, in the southern hemisphere it will be counterclockwise.
(please provide a very detailed explanation for your answer)
Explanation / Answer
The rotational axis of the top will precess counterclockwise as well. You can demonstrate/see this for yourself by using a coin and spinning it. The rotational axis of the top is the same direction as the rotation of the object around its axis.
