物理学是一门以实验为基础的学科,物理学概念的建立和自然规律的揭示大都是以实验为基础的,包括人们提出的各种假说和设想都要通过实验来加以验证。然而,在中学物理教学中,由于受到实验条件和课堂时间的限制,很多实验无法进行,或者由于设备和外界因素的影响,实验效果不理想,给 Physics is an experiment-based discipline. The establishment of the concepts of physics and the disclosure of natural laws are mostly based on experiments. The hypotheses and ideas put forward by people are to be verified through experiments. However, in the middle school physics teaching, due to experimental conditions and classroom time constraints, many experiments can not be carried out, or due to the impact of equipment and external factors, the experimental results are not satisfactory.
