匀变速直线运动中有这样一个推论:初速为零的匀加速直线运动,在第一个Ts内、第二个Ts内、第三个Ts内……第n个Ts内的位移之比为1∶3∶5…(2n-1)(其中n为1,2,3等正整数)。在实际的教学中发现,在某些情况下(n不为正整数时或者不知初速度是否为零),也可用上面的推论来解决匀加速直线运动
In the uniform linear motion, there is an inference that the ratio of the displacement within the nth Ts within the first Ts, the second Ts, the third Ts, ... within the first Ts is 1 : 3: 5 (2n-1) (where n is a positive integer such as 1, 2, 3). In the actual teaching, we found that in some cases (n is not a positive integer or unknown initial velocity is zero), the above inference can also be used to solve the uniform acceleration linear motion
