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 ...
Spin-stabilized magnetic levitation is a phenomenon of magnetic levitation whereby a spinning magnet or array of magnets (typically as a top) is levitated via magnetic forces above another magnet or array of magnets, and stabilised by gyroscopic effect due to a spin rate that is neither too fast, nor too slow to allow for a necessary precession.
The Levitron top device is a design that served as a base for the manufacture of a series of commercial toys under this brand that employ the phenomenon known as spin-stabilized magnetic levitation. This design, with moving permanent magnets, is quite distinct from other versions which use changing electromagnetic fields, levitating various ...
Many toys are made with angular mechanics in mind. These toys include gyroscopes, tops, and yo-yos. When you spin a toy, you apply force to both sides [3] (Push and pull respectively). This makes the top spin. According to newtons third law of motion, [3] the top would continue to spin until a force is acted upon it. Because of all of the ...
Whirligig store. A whirligig is an object that spins or whirls, or has at least one part that spins or whirls. It can also be a pinwheel, spinning top, buzzer, comic weathervane, gee-haw, spinner, whirlygig, whirlijig, whirlyjig, whirlybird, or simply a whirly.
The gyroscopic effect allows the trompo to spin over its point until the force of gravity ends up at an angle with respect to the top's axis of rotation, causing a variation in the location of the center of gravity as the trompo undergoes precession (where the axis of rotation of the trompo moves in a circular path). The fall of the top is ...
Essentially, a gyroscope is a top combined with a pair of gimbals. Tops were invented in many different civilizations, including classical Greece, Rome, and China. [5] Most of these were not utilized as instruments. The first known apparatus similar to a gyroscope (the "Whirling Speculum" or "Serson's Speculum") was invented by John Serson in ...
