An assortment of spinning tops 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 energy, and finally tip ...

2013年4月1日 · The motion of four different spinning tops was filmed with a high-speed video camera. Unlike pointed tops, tops with a rounded peg precess initially about a vertical axis that lies well outside the top, and then spiral inward until the precession axis passes through a point close to the center-of-mass.

Get your own top and watch it spin. Learn how to set it into motion effectively. And see how it moves as it slows down and eventually falls over. The physics of spinning comes into play with any object that is spun. It doesn’t need to be designed for spinning and doesn’t even need to be round. Here a few examples:

Give engineering a spin: experiment with physics while designing and fabricating a custom spinning top! Get hands-on with energy, force, and momentum. How long can your top spin before falling? As long as it’s spinning, a top can remain upright and stable–but eventually, it will begin to wobble and shake. As it slows, it will eventually fall.

Learners will experiment with physics while designing and fabricating custom spinning tops! This activity introduces the “extrude” and/or “revolve” commands in CAD software as well as how to use a slicer to prep files for 3D printing.

2021年12月3日 · The spin of a top depends on its friction, mass distribution, density and shape. Small alterations to these properties have large consequences for the toys’ dynamics, making …

2007年10月22日 · What is the physics of a spinning top? It’s hard to make something that is spinning around change its spinning direction. We say that the spinning thing has "angular momentum". Angular momentum only changes when the object is twisted ("torqued"), in the same way that linear momentum only changes when an object is pushed or pulled.

2024年5月28日 · Explore the fascinating physics of spinning tops: Understand stability, motion, precession, and the impact of energy and friction in this in-depth guide. The humble spinning top, a toy familiar to cultures worldwide, serves as an intriguing example of physics in action.

The rotation of the top about the vertical z-axis (the so-called precession) is described by <I>(t) which is the solution of the differential equation (see the value of the variable phixi [1] above) .

Spinning tops, simple yet mesmerizing toys, have captured the imaginations of people across generations. From ancient times to the modern era, spinning tops have managed to enthrall both young and old with their graceful rotations and intricate physics. In this blog post, we'll dive into the science behind spinning top
