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 ...
When the top is about to stop, hitting it with the top and giving it rotational force makes it spin again. The reason behind the top not falling and rotating is due to the rotational inertia. The power of the spinning top keeps the top balanced. [14] The top turned by hand, transmits kinetic energy to the top, causing it to rotate.
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 ...
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.
A rattleback is a semi-ellipsoidal top which will rotate on its axis in a preferred direction. If spun in the opposite direction, it becomes unstable, "rattles" to a stop and reverses its spin to the preferred direction. For most rattlebacks the motion will happen when the rattleback is spun in one direction, but not when spun in the other.
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 ...
