| Abstract: | The data of the one-dimensional instantaneous collision experiment are recorded by collision process instantaneous digital instrument.The experimental installation and the data collection,transforming and output processes are introduced. A computer program is written to control the data collection and precision is improved by choosing the suitable sampling period.The experiment is adopted to study the Newton second law and complete inelastic collision process. |
