36、础要点突破n 一牛顿第一定律1伽利略理想实验亚里士多德认为，必须_ 物体才能运动；没有力的作用，物体就要 _，这种认识是错误的。伽利略通过 _和科学推理， 得出的结论是： 一旦物体具有某一速度，如果它不受力，就将以这一速度_地运动下去。物体运动状态的改变是指物体 _ 的大小或方向发生变化。2牛顿第一定律和惯性牛顿第一定律的内容是：一切物体总保持_状态或 _状态，除非作用在它上面的力迫使它_。惯性是物体具有保持原来 _状态或 _状态的性质， 任何物体都具有惯性，牛顿第一定律又叫 _。量度物体惯性大小的物理量是物体的_，与速度无关。 质量大惯性大， 运动状态难改变；质量小惯性小，运动状态容易改变。

37、牛顿第一定律描述的事一种理想化的状态，不受力的物体是不存在的。生活中的静止或匀速直线运动是 F合 =0 的结果。揭示了力和运动的关系：力是_物体运动状态的原因。例 1. 下列说法中正确的是（）A运动越快的汽车越不容易停下来，是因为汽车运动得越快，惯性越大 B小球由于重力的作用而自由下落时，它的惯性就不存在了 C一个小球被竖直上抛，当抛出后能继续上升，是因为小球受到了向上 的推力 D物体的惯性是物体保持匀速直线运动状态或静止状态的一种属性，与 物体的速度大小无关 例 2. 如图 1 所示做匀速直线运动的小车上水平放置一密封的装有水的瓶 子，瓶内有气泡，如图所示，当小车突然停止运动时，气泡相对于瓶
