高中物理第一册有关测定匀加速直线运动即时速度和加速度的实验中,用较多的篇幅阐明和推导实验原理公式①和② 在教学实践中,教师虽然用一节课的时间讲解和演示了这一实验原理并推导了上述公式,但学生对上述实验计算式理解仍不很透彻,实验过后印象漠糊,易于遗 In the experiment of measuring the instantaneous velocity and acceleration of uniform acceleration linear motion, the first part of high school physics expounded and deduced the experimental principle formula (1) and (2) in the teaching practice, though the teacher explained and demonstrated the time of one lesson The experimental principle and derive the above formula, but students are still not very thorough understanding of the above experimental formula, after the experiment impression, easy to leave
