大多数学生在面对动态问题时,都会茫然不知所措,甚至会错误理解,导致失分丢分。解决动态问题的关键,就是要能够在动态的问题中找到常见物理量,从而得心应手地解决问题。本文通过具体例题,从运动问题、变焦镜头、不同方向变力以及动态电路下图像问题四个方面,探究动态问题中确定常用物理量的方法,以期学生就动态问题中确定常用物理量的能力得到锻炼和提高。
Most students will be overwhelmed when they are faced with dynamic problems and may even misunderstand them, leading to lost points. The key to solving dynamic problems is to be able to find common physical quantities in dynamic problems so as to solve the problems with ease. In this paper, the method of determining common physical quantities in dynamic problems is explored from the following four aspects: motion problems, zoom lenses, variable force in different directions and image problems under dynamic circuits. In this paper, students are trained to determine common physical quantities in dynamic problems and improve.
