A spinning top, or simply a top, is a toy with a squat body and a sharp point at the bottom, designed to be spun on its vertical axis, balancing on the tip due to the gyroscopic effect. Once set in motion, a top will usually wobble for a few seconds, spin upright for a while, then start to wobble again with increasing amplitude as it loses ...

Spinning Tops (1914) The beigoma ( Japanese : γγΌγ΄γ) is a traditional Japanese top that is approximately 3 cm in diameter and often decorated with kanji . [ 1 ] [ 2 ] [ 3 ] When spun correctly, the beigoma makes a humming sound.
Top most commonly refers to: Top, a basic term of orientation, distinguished from bottom, front, back, and sides; Spinning top, a ubiquitous traditional toy; Top (clothing), clothing designed to be worn over the torso; Mountain top, a mountain peak located at some distance from the nearest point of higher elevation; Top may also refer to:
A trompo is a top which is spun by winding a length of string around the body, and launching it so that lands spinning on its point. If the string is attached to a stick the rotation can be maintained by whipping the side of the body. The string may also be wound around the point while the trompo is spinning in order to control its position or ...
In classical mechanics, the rotation of a rigid body such as a spinning top under the influence of gravity is not, in general, an integrable problem.There are however three famous cases that are integrable, the Euler, the Lagrange, and the Kovalevskaya top, which are in fact the only integrable cases when the system is subject to holonomic constraints.
A teetotum (or T-totum) is a form of spinning top most commonly used for gambling games. It has a polygonal body marked with letters or numbers, which indicate the result of each spin. [1] [2] Usage goes back to (at least) ancient Greeks and Romans, with the popular put and take gambling version going back to medieval times. [2]
The power of the spinning top keeps the top balanced. [15] The top turned by hand transmits kinetic energy to the top, causing it to rotate. The kinetic energy of the spinning top is converted into thermal energy by bottom friction. The top revolves longer by minimizing the conversion of the rotating force into heat. [16]
