1问题的提出例1.历史上有些科学家曾把在相等位移内速度变化相等的单向直线运动称为“匀变速直线运动”(现将之称为“另类匀变速直线运动”),“另类加速度”定义为A=v-v0s,其中v0和v分别表示某段位移s的初速度和末速度.A0表示物体做加速运动,A0表示物体做减速运动.而现在物理 1 PROBLEM PRESENTATION Example 1. Historically, some scientists once referred to unidirectional linear motions with equal velocity variations at equal displacements as “uniform linear motion of shift” (now referred to as “alternative gravitation linear motion”), “alternative Acceleration ”is defined as A = v-v0s, where v0 and v represent the initial velocity and the final velocity of a section of displacement s, respectively, A0 represents the object accelerates, and A0 represents the object decelerates.
