物理学是一门以实验为基础的自然科学，物理实验在中学物理课程学习中有着举足轻重的作用，但在实际学习中，很多传统实验需要去改进。本文通过分析现有验证机械能守恒定律实验验证方法，提出了一个对该实验改进的方法。%Physics is a natural science based on experiments. Physics experiment plays an important role in physics teaching, but in the actual teaching, many traditional experiments need to be improved. This article demonstrates the improved programs by the Authentication of Mechanical Energy Conservation Law.
