在探究物体的加速度与物体质量、合力的关系时,我们有很多实验方法,最常见的就是利用如图1所示的装置进行探究。在此实验中,我们的研究对象是小车,要研究小车的加速度a与合力F合、加速度a与小车质量M的关系,就必须测出每次实验时的加速度、合力及小车质量。加速度我们可以用打点计时器来测量,小车质量可以用天平测得, We have a lot of experimental methods to explore the relationship between the acceleration of an object and the mass and the resultant force of the object. The most common method is to use the device shown in Figure 1 to explore. In this experiment, our research object is a car. To study the relationship between car acceleration a and resultant F, acceleration a and car mass M, it is necessary to measure the acceleration, resultant force and car mass at each experiment. Acceleration We can use RBI timer to measure the quality of the car can be measured with a balance,
