验证变力作用下动量定理和能量定理的新实验方案

New Experimental Scheme for Verifying the Momentum Theorem and Kinetic Energy Theorem with Changing Force

提出了用弹簧验证动量定理、能量定理的实验方法和方案,将变力的测量转换为对时间的测量,解决了变力不能直接测量的技术问题,得到了较他人更加准确的实验结果,丰富了大学物理实验内容和方法。

A new experimental scheme is proposed to verify the momentum theorem and kinetic energy theorem under the action of the variable force.The measurement of the variable force is converted into the measurement of time,and the technical problem is solved that the variable force cannot be directly measured.The obtained results are more accurate than others,and enrich the contents and methods of university physics experiment.
