一、香蕉球自从球王贝利1966年在伦敦世界杯赛中踢出了第一个“美丽的弧线”后,“香蕉球”便成为越来越多球星们的基本功和拿手戏。“香蕉球”为什么会在空中划出了香蕉般诡异的弧线?它包含了什么物理知识?也许当我们明白了其中蕴含的力学原理后,运用物理知识来指导足球运动,足球在我们的脚下也会划出“美丽的弧线”。相关原理气体流速大的地方压强小(伯努利原理)。原理分析如图1所示,假设踢出的球初 First, the banana ball Ever since the king Bailey in 1966 in London World Cup kicked out of the first “beautiful arc ”, “banana ball ” has become more and more players their basic skills and skill. Why Banana Ball Can Draw a Banana-like Arc in the Air? What Physical Knowledge Does It Contain? Perhaps when we understand the mechanics contained therein, we use physical knowledge to guide football. The foot will also draw “beautiful arc ”. Related principles Small pressure where gas velocity is high (Bernoulli principle). The principle analysis is shown in Figure 1, assuming that the ball kicked early
