高中物理中,有许多实验图线,本文将常用的总结如下,供读者参考.1.在测定匀变速直线运动的加速度实验中,利用打点计时器打出的纸带,根据测定的位移数据,计算出小车在T、2T、3T、……时的瞬时速度v_1、v_2、v_3……,作出的V—t图线应是一条直线,该直线的斜率等于小车匀变速直线运动的加速度a.2.在验证牛顿第二定律的实验中,在保持小车总质量M不变,研究加速度a与小车所受外力F的关系时,作出的a—F图线应是一条直线,该直线的斜率的倒数等于M;在保持F不变,研究加速度a和小车(包
In high school physics, there are many experimental plots. This article will summarize the commonly used ones as follows for readers’ reference.1. In the acceleration experiment for measuring uniform speed changes in linear motion, the paper strips are punched out with a tick timer and calculated based on the measured displacement data. The instantaneous speed v_1, v_2, v_3, ... of the trolley at T, 2T, 3T, ... shall be a straight line, and the slope of the straight line is equal to the acceleration of the linear movement of the uniform speed of the trolley a.2 In the experiment to verify Newton’s second law, when keeping the total mass of the car M unchanged and studying the relationship between the acceleration a and the force F received by the trolley, the a-F line drawn should be a straight line with the slope of the line. The inverse is equal to M; in keeping F constant, study the acceleration a and the car (package
