初中物理中的力学知识是对最直观的现象研究,人感觉到手里的物品沉重是因为重力的作用,船漂浮于水面上不会下沉是因为浮力的作用,古人靠钻木取火,是依靠摩擦力,可见从古至今,力与人类的生活是息息相关的。初中物理力学主要是学习重力、浮力、运动和力、质量和密度等。这些教学内容都与生活密不可分,它相比其他章节的教学具有一定优势,它与学生的生活结合紧密,教师要让力学这一章节的教学效率提升,则可以引导学生从自
Mechanical knowledge of junior high school physics is the most intuitive phenomenon of research, people feel the hands of the goods is heavy because of the role of gravity, the ship floating on the water will not sink because of the buoyancy effect, the ancients rely on drilling wood fire is Relying on friction, we can see that since ancient times, strength and human life are closely related. Middle school physics mechanics is mainly to study gravity, buoyancy, movement and force, quality and density. These teaching contents are inseparable from life, it has some advantages over the teaching of other chapters, and it is closely integrated with the life of the students. Teachers should improve the teaching efficiency of the chapter in mechanics so that they can guide students from self-
