一般来说，物体的运动发生在一个封闭的环境中，物体与封闭壁的碰撞是可能的。为了预测物体在这种情况下的动力学，我们必须知道碰撞时会发生什么。因此，问题是：如果人们知道物体的碰撞前动力学以及物体和壁的特性，人们想要预测碰撞后动力学。这个问题是相当古老的，它出现在文学在1668年。直到1984年，牛顿的模型似乎足以解决这个问题。但人们发现情况并非如此，人们对这个问题重新产生了兴趣。本文的目的是处理刚体的平面碰撞的问题，分类不同的模型在文献中发现，并提出一个新的模型，这是一个推广的大多数这些模型。
In general the motion of a body takes place in a confined environment and collision of the body with the containing wall is possible. In order to predict the dynamics of a body in this condition one must know what happens in a collision. Therefore, the problem is: if one knows the pre-collision dynamics of the body and the properties of the body and the wall one wants to predict the post-collision dynamics. This problem is quite old and it appeared in the literature in 1668. Up to 1984 it seemed that Newton's model was enough to solve the problem. But it was found that this was not the case and a renewed interest in the problem appeared. The aim of this paper is to treat the problem of plan collisions of rigid bodies, to classify the different models found in the literature and to present a new model that is a generalization of most of these models.
