目前,有些中学正在逐步开设有关电脑的课程,组织电脑应用的课外活动小组。这对培养能力,锻炼思维都有深远的意义。在中学,电脑不但可以用来解数学题、作游戏,还可应用在物理实验上。例如:验证牛顿第二定律,可用电脑配合实验、分析处理数据,得出正确的结论。1.验证牛顿第二定律实验简介(1)按图1安装好实验装置,调整好斜面的倾角(调整垫块⑧),使小车②能在斜面上匀速滑下(挂码④此时暂不挂),这时小车重力沿斜面方向的分力和滑动摩擦力平衡,此后小车在斜面上运动所受合外力就是绳子对它的拉力
At present, some middle schools are gradually setting up computer courses and organizing extra-curricular activities for computer applications. This has profound implications for cultivating ability and exercising thinking. In middle school, computers can be used not only for solving math problems, playing games, but also for physics experiments. For example: to verify Newton’s second law, the computer can be used in conjunction with experiments, analysis and processing of data to arrive at a correct conclusion. 1. Verification of Newton’s Second Law Experiment Introduction (1) Install the experimental device as shown in Figure 1. Adjust the inclination of the slope (adjust the block 8) so that the car 2 can slide down on the inclined surface at a uniform speed. Hung), then the gravity of the trolley’s gravity along the slope direction is balanced with the sliding friction force. Afterwards, the external force exerted by the trolley on the inclined plane is the pulling force of the rope on it.
