• 请教一道有关参照物的物理题假期到了,班上的几个同学送小明乘火车回家.列车徐徐地开动了,小明坐在窗边,却看到同学们渐渐向后退去.奇怪,究竟是谁在运动呢?我的回答：静止是相对的,运动是绝对的.运动是绝对的,世界万物时刻都在运动.而静止是相对的,如果以火车为参照物,火车是运动的,那么小明也是运动的,这两种物质处于同一状态.所以以火车为参照物就是以小明为参照物.而小明相对于火车却是静止的.站在小明的角度上,对小明来说,小明看到同学们渐渐向后退去,那么其实就是那他自己当作了参照物（判断同学们在运动,以小明他自己为标准物）,以小明为参照物同学们是运动的（同学们渐渐向后退）,那也可以说成以火车为参照物,小明坐在火车窗边看到同学们渐渐在向后退去.总结：1,静止是相对的,运动是绝对的,世界万物都在运动.2 说物体是在运动还是静止,要看是以另外哪个物体做标准.这个被选做标准的物体就是参照物.判断一个物体是运动的还是静止的要看这个物体与所选参照物之间是否有位置变化.若有位置变化,则物体相对于参照物是运动的；若位置没有变
