归纳法,即通过有限次递推,发现事物内在规律的一种方法,是研究物理问题的重要方法之一. 例1 一弹性小球自h0=5m高处自由落下, 它与水平地面每碰一次,速率即减为碰前的7/9,不计每次碰撞的时间,计算小球从开始下落到停止运动通过的总路程s和所经历的时间t(g取10m/s2). Inductive method, that is, a method of discovering the internal law of things through recursiveness of finite times, is one of the important methods for studying physics problems. Example 1 An elastic ball falls freely from h0=5m high, and it touches the horizontal ground every time. Once, the rate is reduced to 7/9 before the collision, excluding the time of each collision, the total distance s from which the ball has fallen from the beginning to the stop motion and the elapsed time t (g takes 10m/s2).
