在学习高中物理问题的过程中,我们常常会遇到求物体速度最大问题,那么物体何时速度最大呢?同学们在求解此类问题常常感到无从下手.下面举例分析,希望对同学们能够有所启迪,相信对提高同学们的解题技能会有一定的帮助.一、物体做直线运动时,当物体所受的合外力为零时,往往速度最大.例1空气对运动物体的阻力实际 In the process of learning high school physics, we often encounter the problem of seeking the maximum speed of the object, then when the object is the fastest speed? Students often feel unable to solve such problems start with the following analysis, I hope the students can have Inspired, I believe that to improve students’ problem-solving skills will be a certain amount of help. First, the object to do linear motion, when the object suffered by the combined external force is zero, the maximum speed .Example 1 air resistance to moving objects Actual
