《普通物理》教学中刚体平动和转动的对比教学研究

学生在学习刚体转动时通常难以理解其中抽象的物理概念.而刚体转动中的角量、力矩、转动惯量和刚体平动中的线量、力、质量有着一定的相似性.刚体转动中的一些定理也和刚体平动中的相关定理有相似之处.在进行刚体转动的教学时,要让学生对熟悉的刚体平动中相关知识点进行对比,让学生自然的从平动学习过渡到转动学习,轻松地掌握刚体转动中的知识点,从而达到良好的教学效果.

Comparative Study of Teaching of Rigid Body Rotation and Motion

The Abstract physics concept of rigid body rotation is difficult to understand for the students.There are similarities among the physical quantity and theorem like angular quantity and linear quantity,moment and force,moment of inertia and mass.The similarities can be applied to the students＇ rigid body rotation learning,which will make the student transform thinking from rigid body motion and grasp the knowledge point of rigid body rotation and the ideal teaching effect will be achieved.
