牛顿第三定律
【教学目标】
1.知识与技能：理解作用力和反作用力的关系，掌握牛顿第三定律确切含义；学习研究物理问题的方法；
能区别平衡力与“作用力和反作用力”。
2.过程与方法：进一步学习“研究现象，总结规律”的方法。能分清实际问题中的作用力和反作用力。
3.情感态度和价值观：培养学生探究生活中物理问题的习惯，提高科学素养。
【教学重点、难点、疑点】
重点：牛顿第三定律的内容及确切含义。
难点：作用力、反作用力与平衡力的区别。
疑点：马拉车向前运动是因为马拉车的力大于车拉马的力吗？
【教学方法】
实验法（演示实验，学生互动实验，学生分组实验），讨论法，类比法等。
【教学仪器】
绳一根；演示用大弹簧秤、小弹簧秤各一个；带发条的小车，薄木板各一个，8根相同的园形铅笔；带有条形磁铁的小车两个；分组实验用的弹簧秤若干个等。（学生课前备好）两
双溜冰鞋或两个滑板
【教学过程】
（一）创设情景、引入新课
“同学们，这一节课我们模拟电视台做一期节目，研究物体间力的作用特点，我是主持人，你们是演员，现在请以热烈的掌声预祝我们将获得成功。”然后采访一位同学谈谈鼓掌时两
只手的感觉，说明了什么？（学生回答：___________________________ ）由此引入新课。
（二）问题探究、学习新课
探究一：物体间的力作用是相互的，一个叫作用力另一个叫反作用力。
两穿溜冰鞋同学相距一定距离对面站定，每个学生拿着绳子的一端. 当两个学生一
块用力拉绳时，两同学同时向中间移动。
（采访其中一位同学，通过绳子对另一同学作用时，有没有感受到另外的同学对你的
作用，产生的作用是另外一个同学主动拉你所产生的结果吗？学生回
答：_____________________ ）
然后再让这位同学反过身子来不主动拉，而是让另一位同学自己主动拉。发现两辆
车还是相靠近，这时再采访刚才那位同学，这时知道你对另一同学有力的作用时，同时你也会受到另一同学的作用。
请同学总结：物体间这一对相互的作用力，叫做作用力和反作用力。
实例：（再采访会踢球的同学，踢球时脚会有什么感觉，哪两个力是作用力和反作用
力？学生回答：_______________________ ）
探究二：作用力与反作用力有哪些关系和特点？
实验与探究，请同学们带着下列问题进行观察分析：
（1 ）是否先有作用力，后有反作用力？
我的猜想是：（请同学猜想再实验验证。）
（2）这两个力的性质是否相同
?
我的猜想是：（请同学猜想再实验验证。）
（3）这两个力的方向是否相同？
我的猜想是：（请同学猜想再实验验证。）
演示实验1.在桌面上放两辆相同的小车，两车用细线套在一起，两车间夹一弹簧片.当用火烧断线后，两
车被弹开.
演示实验2?在两辆小车上各固定一根条形磁铁，当磁铁的同名磁极靠近时，放手小车
演示实验3.在桌面上并排放上一些圆杆，可用铅笔.在棒上铺一块三合板，板上放一辆遥控电动玩具小车?用遥
控器控制小车向前运动时，板向后运动；当车向后运动时板向前运动.

U 口 C C C C ~'
（同学进行实验分析讨论可以得出以下结论：）
①相互性：两个物体间力的作用是相互的. 施力物体和受力物体对两个力来说是互换的.
②同时性：作用力消失，反作用力立即消失.没有作用就没有反作用.
③同一性：作用力和反作用力的性质是相同的.这一点从几个实验中可以看出，当作用力是弹力时，反作用力也是弹力；作用力是摩擦力，反作用力也是摩擦力等等.
④方向：作用力跟反作用力的方向是相反的，在一条直线上. 总的来说就是：同生同灭异物反向且共线
探究三、作用力与反作用力的大小关系。
一、（学生互动试验）请一个高个同学与一个矮个同学进行拔河比赛，观察胜负。讨论：两同学之间的拉力大小存在什么样关系？如何验证？（学生共同讨论确定方案）
方案如下：把两个弹簧秤勾在一起，模仿拔河比赛，其中一个弹簧秤相当高个同学，另一个相当于矮个同学，并分两种情况进行。
1.两弹簧秤勾在一起拉，处于静止不动时（模仿拔河比赛，双方处于僵持状态）；
2.两弹簧秤勾在一起拉，并向一方运动（相当于比赛绳子被拉向胜一方时的状态）；
（学生分组实验）：做5分钟时间，教师巡回指导，并要求学生对秤先校零，让学生自己得出在各种状况下，两拉力大小的关系。
N S | N S
（演示实验）：老师亲自用大弹簧秤和小弹簧秤模仿拔河比赛，正确做好示范动作，并画图进行解释，注意两力的方向。师生共同讨论得出
牛顿第三定律：1.内容：两个物体之间的
作用力和反作用力总是大小相等，方向相反，作用在同一条直线上。 2 ?公
式：F= —F'。
学以致用：
现在我们来分析一个问题，拔河比赛。（有人认为，在拔河比赛中既然双方的作用力与反
作用力大小相等，应该不可能分出胜负。实际上却总有一方获胜，这是否违背牛顿第三定律？引导学生对其中的一方进行分析：
1、分析拔河的各队受到哪些力的作用？
2、甲对乙的拉力和乙对甲的拉力是否相等？
3、结合牛顿第二定律得出答案。让学生在解决问题的过程中产生成
功感。再让学生独立解释其他生活现象：
1、马拉车时，为什么车会向前走而马不后退呢？
2、一青年将别人脸打伤，还对警察狡辩说，根据牛顿第三定律，我的手和伤者脸彼此间的作用力大小是相
等的。请问如果你是警察你该怎样驳斥这个青年？
（学生会展开热烈的讨论：同样大小的力作用在两个物体上会产生不同的效果. 效果不
同是什么原因呢？这个效果由物体本身的特性和物体受到其它力的情况有关. 物体能够
承受的压强大就不易受伤、是否发生运动状态的变化还要看物体受到的其它力的情况。）
探究四：作用力、反作用力跟平衡力的区别
共同点：它们大小相等、方向相反、作用在一条直线上
作用力与反作用力一对平衡力
作用对象相互作用的两个物体（异物）一个物体上（同物）
作用性质一定冋种性质不一定冋种性质
作用时间
两个力同时产生，同时变化，同时消
失一个力的产生、变化、消失不一定影响另一个力
作用效果两个力各有各的效果
两个力共同作用，效果是使物体平衡
例题：吊在天花板上电灯泡，分析物体受几个力? 并指出每一个力的反作用力、以及平衡力？要求学生上黑板做，画出示意图，然后订正错误，并分析作用力、反作用力与平衡力的区别。
（三）小结巩固，知识迁移。
1作用力与反作用力三个一样和两个不一样：大小一样、性质一样、力的产生、
消失、变化一样；方向不一样、作用对象不一样。
2、作用力与反作用力与一对平衡力的联系与区别。
3、课后思考：
水上的滑板运动员是怎么样在水上运动的？（实际应用）火箭是怎么升上太空的？（对科技的发展有着很大的作用）
4、作业：完成课本88页第4题。
板书设计
一、力是物体间的相互作用
1、力的作用是相互的。
2、作用力与反作用力。
二、牛顿第三定律：
1 ?内容：两个物体之间的作用力和反作用力总是大小相等，方向相反，作用在同一条直线上。
2、作用力与反作用力关系：
（1）三个一样：大小一样，力的性质一样，力的产生、消失、变化情况一样
（2）两个不一样：方向不一样、作用对象不一样。
三、平衡力跟作用力与反作用力

T: Hi, morning, class. Nice to see you on this special day, the day when you become a senior two grader. I am happy to be with you helping you with your English. Today we are to read about a certain scientist. But f irst let’s define the word “scientist”. What is a scientist? A scientist is a person who works in science, trying to understand how the universe or other things work. Scientists can work in different areas of science. Here are some examples: Those that study physics are physicists. Those that study chemistry are chemists. Those that study biology are biologists. Step II 头脑风暴 Ask the students to try the quiz and find out who knows the most. T: There are some great scientific achievements that have changed the world. Can you name some of them? What kind of role do they play in the field of science? Do these achievements have anything in common? Match the inventions with their inventors below before you answer all these questions. 1.Archimedes, Ancient Greek (287-212 BC), a mathematician. 2. Charles Darwin, Britain (1808-1882). The name of the book is Origin of Species. 3. Thomas Newcomen, British (1663-1729), an inventor of steam engine. 4. Gregor Mendel, Czech, a botanist and geneticist. 5. Marie Curie, Polish and French, a chemist and physicist. 6. Thomas Edison, American, an inventor. 7. Leonardo da Vinci, Italian, an artist. 8. Sir Humphry Davy, British, an inventor and chemist.

Period 2Reading The General Idea of This Period This is the second period of this unit.This period focuses on the reading passage, which is about John Snow and King Cholera.At the beginning of the period, the teacher can design some activities to draw the students’ attention to read.In order to attract the students’ attention, the teacher had better offer the students the opportunities to have a competition about some information about some scientists mentioned in the Warming up.Then the teacher can make full use of the questions in the Pre-reading.This step is designed to make for preparing for understanding the passage. Reading skills are very important for senior students.For the first reading, we intend to cultivate Ss’ skimming ability and scanning ab ility.First ask the students to scan it and tick out what...are mentioned in the passage.Then let the students read fast to find out the main idea of each paragraph.In order to stimulate Ss to take part in the class activity more actively, the teacher can organize a group competition to see which group can finish the task fastest and best.For the second reading, the students are expected to know some details about the https://www.doczj.com/doc/e24972548.html,ter on, the teacher will present some questions for the students to answer and at the same time they are asked to finish filling in the chart.The third time is to read for further information.This part is designed to get Ss into the habit of reading a passage as a whole, that is, to get the general idea.Another purpose of this part is to ask Ss to pay attention to the details. To develop Ss’ further understanding ability, the teacher can design some questions, whose answers are beyond lines.So the teacher will help them to read between the lines, thus Ss can gradually get the ability to understand the implied meanings.In this step, the teacher asks Ss to read it again in order to make them think about the organization of the whole passage, and this method can help them not only in their understanding this passage but also in writing a short passage. To consolidate the content of the passage, Ss are required to retell it according to the main idea.In order to arouse the Ss’ interest; the teacher can hold a competition between groups.After the students understand the whole passage, they are asked to have a topic discussion. Teaching Important Points Have a good understanding of the text by doing the exercises. Get the students to learn different reading skills, especially gist reading and comprehending beyond lines. Teaching Difficulties Know the meanings between lines and beyond lines. Learn different reading skills for different reading purposes. Teaching Aids Multi-media classroom and other normal teaching tools. Three Dimensional Teaching Aims Knowledge Aim Have a good understanding of the text through the exercises. Ability Aims Grasp some reading skills. Develop the ability to describe some famous scientists. Emotional Aims
