物理学是一门实验学科,其中涉及到物理量的测量和计算.为了测量、比较量的大小,引入了单位;量与量之间的联系决定了单位之间的联系,根据这种联系,建立了单位制.教材中有涉及到单位制的教学,内容相对浅显学生也容易接受,然而在以后的反思过程中,学生往往会出现一些疑问,混淆概念 Physics is an experimental subject, which involves the measurement and calculation of physical quantities. To measure and compare the magnitudes, a unit is introduced; the link between quantity and quantity determines the relationship between units and is established based on this connection. In the unit system, there are textbooks involving the unit system. The content is relatively easy to accept. However, in the future reflection process, students often have some questions and confuse concepts.
