多体问题是高考考查的热点,物理过程复杂,综合性强,运用转化的思维策略,可以将复杂的物理过程程序化地分解,从而达到化整为零,化繁为简、化难为易的目的.例1正在沿平直轨道以速度v向右匀速行驶的车厢内,前面高h的光滑架上放着一个小球随车一起运动,如图1所示,忽然车厢改以加速度a匀加速运动,小球落下,问: The multi-body problem is the hot spot of college entrance examination examination. The physical process is complex and comprehensive. By using the transforming thinking tactics, the complex physical process can be decomposed programmatically so that the whole process is zero and the complexity is easy. Example 1 is a straight track along the straight track at a speed v to the right uniform speed carriage, the front of the high-h carriage put a small car with the car movement, as shown in Figure 1, suddenly the car changed with acceleration a uniform Accelerate the movement, the ball fell, asked:
