如果你想踢香蕉球,那么触球部位要偏离重心。
If you want the ball to curve, give it lots of spin by hitting it off-centre.

好个漂亮的香蕉球!
What a beautiful banana shot!

另一个有趣的现象是:即使摩擦系数为零,如果你踢球偏离了它的重心,仍然能够踢出香蕉球。
The other interesting effect was that even if the coefficient of friction is zero, the ball still gains some spin if you kick it with an offset from its centre of gravity .
1. 弧旋球(Screw shot)是足球运动中的技术名词,又称“弧线球”,“香蕉球”。 弧旋球指运动员运用脚法,踢出球后并使球在空中向前作弧线运行的踢球技术。弧线球常用于攻方在对方禁区附近获得直接任意球时,利用其弧线运行状态,避开人墙直接射门得分。
