如图所示，甲是探究“动能的大小与什么因素有关”的实验装置,实验中让同一钢球从斜面上不同的高度由静止滚下，碰到同一木块上．乙是探究“阻力对物体运动的影响”的实验装置，实验中让同一小车从斜面上相同的高度由静止滑下，在粗糙程度不同的水平面上运动．请回答下列问题：

　　（1）甲实验的目的是探究钢球动能的大小与             的关系；实验时，它是通过观察            ，从而判断钢球动能的大小。
　　（2）进行乙实验时，每一次都让同一小车从斜面上相同的高度由静止滑下，其目的是使小车在水平面运动的起始             相同；通过观察小车在粗糙程度不同的水平面上运动            来判断小车在不同的水平面受到            的大小．从而可以推理：如果运动的物体不受力，它将                。
