两个匀变速直线运动相遇问题,是匀变速直线运动规律的综合应用,是教学难点,而相遇的次数分析更是难上加难,为了化解此难点,今以两个匀加速直线运动相遇次数分析作为例子,供大家参考。题目:在平直的轨道上,甲、乙两车相距为x_0,同向同时开始运动。甲在后面以初速度v_1、加速度a_1做匀加速度直线运动,乙在前面以初速度v_2、加速度a_2做匀加速度直线运动。假定甲能从乙的旁边通
Two uniform speed linear motion encounter problems, is the uniform application of uniform linear motion law is teaching difficult, but the number of encounters is even harder to meet, in order to resolve this difficulty, with two uniform linear motion to meet the number of times Analysis as an example, for your reference. Title: On a straight track, A and B vehicles are separated by x_0 and move in the same direction at the same time. A in the back to the initial velocity v_1, acceleration a_1 do uniform acceleration linear motion, B in the front to the initial velocity v_2, acceleration a_2 do uniform acceleration linear motion. Suppose A can pass from the side of B.
