标题： Attraction of a jerk

摘要： 急动度在许多游乐场过山车的刺激体验中起着关键作用。 除了探讨急动度的物理方面，我们还研究了在流行的旋转茶杯游乐项目中乘客之间吸引力的实证观察。 通过建模旋转平台的复杂系统，我们表明由变化加速度引起的拟扭矩会导致急动度运动以及骑乘者之间的吸引力。 我们的数值分析证实了实证观察结果，突显了吸引力与急动度之间的联系。 显示英文摘要

摘要： Jerk plays a pivotal role in the thrilling experience of many amusemement park rides. In addition to exploring the physical aspect of jerks, we tackle the empirical observation of an attractive force between passengers in the popular attraction, the spinning teacups. By modeling the complex system of rotating platforms, we show that pseudotorques induced by changing acceleration lead to jerky movements and an attractive interaction among riders. Our numerical analysis confirms the empirical observations, highlighting the connection between attraction and jerks.
