物体间发生弹性碰撞时,不仅系统动量守恒,而且系统的能量也守恒。因此在求解弹性碰撞问题时,如果能够掌握弹性碰撞的一些规律,无疑会给快速、正确的解题带来极大的方便。下面我们就一起来探讨其中的规律,以提高解题速度和技能。一、完全弹性碰撞模型如图1所示,质量为m_2的小球2静止在光滑水
When an elastic collision occurs between objects, not only the momentum of the system is conserved, but also the energy of the system is conserved. Therefore, when solving the elastic collision problem, if we can grasp some laws of elastic collision, it will undoubtedly bring great convenience to fast and correct problem solving. Here we work together to explore the laws in order to improve the speed and skills of solving problems. First, the fully elastic collision model shown in Figure 1, mass m_2 of pellets 2 still in the smooth water
