物理学是以实验为基础的科学。物理实验在初中物理教学中具有十分重要的作用。特别是随着素质教育的推进,尤其对学生自主性学习及创新意识的培养具有重要作用。力学实验中,涉及的范围广(测量长度、速度、密度、力、压强、功、机械效率等),使用的基本仪器多(刻度尺、弹簧秤、天 Physics is an experiment-based science. Physics experiment plays a very important role in junior high school physics teaching. In particular, with the advancement of quality education, it has played an important role in cultivating students’ independent learning and innovation consciousness. In the mechanical experiments, the scope involved is wide (measuring length, speed, density, force, pressure, work, mechanical efficiency, etc.), and the basic instruments used are many (scale, spring balance, day
