对于需要应用动量守恒定律来处理的涉及第三个物体的两体问题,这个“第三者”如何处置,在列式求解时要不要把这个“第三者”概括进去?有不少同学感到很茫然,无所适从.其实这个“第三者”在列式求解时要不要概括进去要视具体情况而定,同学们在碰到这类问题时一定要仔细分析“第三者”是如何“插足”那两个物体的,才能据此作出正确的判断.下面我们就这个问题进行分析.
For the two-body problem involving the third object that needs to be applied to the law of conservation of momentum, how does the “third person” deal with it and whether or not the “third person” should be included in the solution of the column equation? Many students feel that It’s awkward and incomprehensible. In fact, this “third party” should not be summed up when it comes to solving the column equations. It depends on the specific circumstances. Students must carefully analyze how the “third party” is involved in such problems. "The two objects can be used to make correct judgments. Here we analyze this issue.
