关于“验证力的平行四边形定则”中的理论值与实验值,是一个多年来常在实验题中出现的问题,也是一直在物理教师中产生争议的问题,面对目前物理教师中存在的两种截然相反的观点,有必要给予澄清,以利于实验教学.
The theoretical value and the experimental value in the “parallelogram principle of verification power” are a problem often found in experimental problems over the years and have always been a controversial issue among physics teachers. In the face of current physics teachers There are two diametrically opposed views, it is necessary to give clarification, in order to facilitate experimental teaching.
