It is well known that the problems about the elastic collision of two bodies in 2 - d space can not be exactly solved generally 摘要众所周知一般说来,关于两个物体的弹性碰撞的一些问题无法被确切解决。
Acceleration , for instance , will be offset by air resistance and rolling friction , instead of a " max velocity . " robots crashing into the side of another robot will push it sideways , based on laws of friction and a semi - elastic collision 例如,加速度将会被空气阻力和滚动摩擦力抵消一部分,而不只受到“最大速率”的限制。根据摩擦力和半弹性碰撞原理,机器人撞到另一个机器人的一侧时会把它推到一边去。
