气垫导轨上不依赖重力的质量测量

Measurement of Mass on Air Track with no Dependence of Gravity

该文设计的4种在气垫导轨上不依赖重力进行质量测量的实验,均在传统气垫导轨实验的基础上,通过添加少量其他实验仪器即可完成。介绍了不依赖重力的质量测量方法——碰撞法、简谐振动法、恒定拉力法(牛顿第二定律法)和压缩弹簧法,实验内容具有重要的实际意义。

Four kinds of experiments of mass measurement we designed on air track with no dependence of gravity are introduced.These experiments are based on traditional air track experiments and will be carried out with addition of several physics instruments,including collision method,vibration method,constant-force method and spring compression method.They are both practical about the mass measurement in a spacecraft and beneficial for the teaching of physics experiments.The teaching practice in physics experiment center of our college shows that the experiments are good for increasing students’ interest in physics experiments and their initiative and creative ability.
