摘要: 打水漂是人类最古老的游戏之一.通过对打水漂进行简化定量分析得出,石块弹跳,只有在抛掷的初速度超过某个临界值时才会发生,并且给出了石块的最大弹跳次数.

关键词: 打水漂, 流体, 浮力, 阻力, 碰撞

Abstract: The motion of a stone skipping over a water surface is one of human s most ancient games.A simplified description of the collisional process of the stone with water is proposed.The stone s bounce is happened when the initial velocity of a throw surpasses a marginal value.The maximum number of bounces is estimated.

Key words: stone skipping, fluid, lift force, resistance, collision
