对于计算运动物体的平均速度 ,一些同学感到很棘手 ,总把平均速度与速度的平均值混为一谈。那么什么是平均速度 ?求平均速度应该注意哪些问题呢 ?平均速度是表示变速运动物体的平均运动快慢的物理量。它的大小等于变速运动物体在单位时间内通过的路程。其计算公式 :υ =st ,可 For the calculation of the average speed of moving objects, some students find it difficult to confuse the average speed with the average speed. So what is the average speed? What should be paid attention to the average speed? The average speed is the physical quantity that represents the average speed of the moving object in the speed change. Its size is equal to the distance traveled by the moving object in unit time. Its calculation formula : υ =st , can
