物理概念是物理学中的重中之重,是物理规律和理论的基础。比如,没有光线、光的反射、折射等概念就无法研究光学;没有电路、电流、电压等系列概念就不能形成电学。因此,理解物理概念的内涵是提高物理教学质量的关键。为了学生能够清楚、准确地掌握概念,我们必须从以下几方 The concept of physics is the top priority in physics and the basis of the laws and theories of physics. For example, no light, light reflection, refraction and other concepts can not study optics; no circuit, current, voltage and other concepts can not form a series of electrical. Therefore, understanding the connotation of the concept of physics is the key to improving the quality of physics teaching. In order for students to grasp the concepts clearly and accurately, we must learn from the following aspects
