高中三年在物理学中有很多东西要学习,学生感觉更多,不是老师吗这三年的教学内容非常紧凑,学生需要不断将物理知识投入大脑。系统梳理 知识总结, 归纳式解决问题法则都很重要。为了更好地了解将来在听课时应该“理解”的内容,下课后应该练习什么问题,形成良性循环。 2020-10-26
2.the main difference between interaction force and balance force: whether it is the same object
six important steps to learn high school physics
circuit simplification steps
if not,then there is elasticity with the contact object.
step 1: remove the disconnected switch as required by the title,turn the closed switch into a wire.
"force analysis" solution book!
if possible,there is no elastic force between the contact object;。作业不是问题。完成老师留下的作业,您必须尽力使老师的作业问题清楚明了,努力做到一切顺利做吧这不是空话,前, 您已经完全理解了本教程中的难点和容易出错的要点。一般来说, 这本书将附带一个推导过程,自己推导之后 将其与书进行比较
in the second year of high school,is a watershed in the differentiation of grades,achievement will be polarized: the line will skyrocket,if it doesn't work, it will go from bad to worse.
step 2: turn the ammeter into a wire (you can keep it depending on the situation).
one.use the "hypothetical method" to determine the presence or absence of elasticity and the direction of friction
high school physics learning method: habits and methods of physics learning
comparative recognition or judgment
1.read teaching materials and reference books.be sure to patiently read it over and over again,understand the basics.this step is the most critical step,is the basis for all subsequent work,not sloppy.
six ways to teach you physics calculation problems to get high scores skillfully
1.use the "hypothesis method" to judge whether there is elasticity,you can first assume that there is elasticity,then determine whether it is consistent with the actual situation of the research subject; it can also be envisaged to "evacuate" the objects in contact with the research subject,to see if the research object can maintain its original state,

let middle school physics go from passing to excellent,it is estimated that you are short of a "three-to-many" learning method
所谓的“三多”意思是“了解更多,多加练习,总结更多”,要了解更多,那就是掌握课前预览和听课。真正了解; 多加练习,下课后多做些运动,真正的高手; 总结更多,考试后总结和分析自己的错误和弱点,为了将来克服真正了解自己的长处和短处。无论,头等大事就是设法弥补,以免妨碍以后的学习。如果没有推论或推论不正确,有两种情况,一是没有学到相关知识,第二个原因是以前学到的一些知识没有很好地掌握。学生周围有很多物理现象,就像上课的钟声,漂浮在水中的乒乓球,天空中的彩虹灯和电话 etc.,and,everyone is consciously or unconsciously applying the laws of physics all the time.use a lever when prying a rock,leaning the body "in" when riding a bicycle to turn.all this brings us convenience in learning physics.the law is universal,therefore, it can be directly imitated and used.what is abstracted is something with essential universal meaning,it can repeatedly appear in many physical phenomena.e.g,objects immersed in liquid are subjected to upward force called buoyancy,this definition applies to all liquids.and,we can also extend it to use in gas.
selecting research objects and searching for interrelationships are the two keys to solving multi-body problems.the selection of research objects needs to be based on different conditions,or use the isolation method,that is, the research object is extracted from the system in which it is located for research; or the overall method is adopted,that is, the system composed of several research objects is studied as a whole; or the isolation method and the overall method are used interchangeably.
1.for multi-body problems,to correctly select the research object,good at finding mutual connections
the first part of learning is preview.some students don't pay attention to this link before the class.i would say that i never had this habit in junior high school.here we need to pay attention,high school physics is different from junior high school.regardless of the degree required from the course,or the capacity of the classroom,both require us to preview what we have learned before class.
7 steps to learn "circuit simplification",simple solution to circuit problems!
1.judge whether the object is moving or stationary (compared with the reference object: if there is a position change, it is moving,no position change is static): communication satellites, the moon walks through the clouds, the tortoise and the hare race,when choosing the reference object, try to choose the object that appears in the title.
