Abstract: 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.
