打点计时器的使用是一个重要的实验内容.涉及到打点计时器的实验有:练习使用打点计时器,测定匀变速直线运动的加速度,探究加速度与力、质量的关系,验证机械能守恒定律,测定重力加速度等.随着新课标理念的逐步推广,上海、广东等地高考实验题的比重正在增加,近几年还在选择题、计 The use of a tick timer is an important experiment content. Experiments involving the tick timer include: practicing using a tick timer, measuring the acceleration of a linear motion at constant speed, exploring the relationship between acceleration and force, and mass, verifying the law of conservation of mechanical energy, and measuring Gravity acceleration, etc. With the gradual promotion of the concept of the new curriculum, the proportion of college entrance examination lab questions in Shanghai and Guangdong is increasing.
