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 …

The rattleback (also known as the Celtic stone, or wobble stone) is a fascinating object. You spin it in one direction, it slows down, wobbles, and then starts spinning in the opposite direction! …

The rattleback is a top that defies convention. It spins freely in one direction, but if spun in the other direction, its rotational motion becomes unstable; it starts to wobble and then will begin …

Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin (i.e., a spin-bias). If spun in one direction, the rattleback will exhibit seemingly stable rotary motion. If spun in the …

How Does a Rattleback Work? A quick explanation for the classic physics toy, the Rattleback™. The Rattleback takes the shape of an elongated asymmetrical semi-ellipsoid – a squashed …

2019年9月1日 · Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin (i.e., a spin-bias). If spun in one direction, the rattleback will exhibit seemingly stable rotary motion. If …

A rattleback is an object that rotates in only one direction. If you try to rotate it in the "wrong" direction, it stops and begins rotating in the other direction. There are no internal parts .. no …

2017年9月12日 · The rattleback is a boat-shaped top with an asymmetric preference in spin. Its dynamics can be described by nonlinearly coupled pitching, rolling, and spinning modes. The …

2020年8月1日 · The rattleback, also known as the celtic stone (or simply, the celt), is a rigid semi-ellipsoidal (canoe shape) object which exhibits rotational preference. More precisely, when …

2019年1月15日 · Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin. If spun in, say, the clockwise direction, the rattleback will exhibit stable rotary motion. If spun in …
