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 ...
The stem may be used as a handle to pick up the top, and is also used to spin the top into motion. When a tippe top is spun at a high angular velocity, its stem slowly tilts downwards more and more until it suddenly lifts the body of the spinning top off the ground, with the stem now pointing downward. Eventually, as the top's spinning rate ...
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.
Beyblade (ベイブレード, Beiburēdo, diminutive Bey, from the diminutive of beigoma) is a line of spinning-top toys originally developed by Takara, first released in Japan in July 1999, along with a related manga series. Following Takara's merger with Tomy in 2006, Beyblades are now developed by Takara Tomy.
Earth’s inner core, a red-hot ball of iron 1,800 miles below our feet, stopped spinning recently, and it may now be reversing directions, according to an analysis of seismic activity.
This theorem does not apply to devices consisting of a properly configured magnetic base and corresponding magnetic top, however, because the non-static nature of the spinning magnetic top within a threshold of lower and upper RPM spin rates acts as a balanced precessing gyroscope to prevent the poles of its magnetic field from fully aligning ...
One of the top reasons a user can't find their emails is due to settings from a third-party email client such as Outlook or the Mail app on your phone. Chances are the settings in the program are set to delete the emails from the AOL server each time you check your mail.
A police officer in the Virginia suburbs of Washington, D.C., narrowly escaped an out-of-control car that came speeding at him from across the median during a traffic stop — and it was all ...
