人教版新课标高中物理必修2平抛运动说课稿2篇
（5）高度不同，对平抛运动距离有何影响，是否因为高度减小后下落时间减小，所以要增大速度才能达到相同的距离？（教学实践证明，这种想法在学生比较多见。已经不自觉的沿用了自由落体运动的规律，又隐隐有运动等时性的痕迹。应引导学生这一结果还需实验验证。）教师的引导：其实，我们所提出的看法都跟平抛运动的规律有关系。那么平抛运动究竟有怎样的规律呢？以前学过的直线运动知识还能用于今天的内容吗？由此逐步使学生意识到分析平抛运动须采用运动合成与分解这一方法。三、实验验证自主探究（15分钟） 物理是实验科学，多媒体教学不能代替实验。本教学设计的第三个环节是实验验证，鼓励学生自主探究。引导学生根据自己的猜想（实验目的）设计实验进行验证。（1）介绍手持式平抛竖落仪，引导并小结实验要领：听两小球下落声音判断其下落时间。体会合运动和分运动是等时的。
人教版新课标高中物理必修2万有引力定律说课稿2篇
学生中存在这样的问题：既然宇宙间的一切物体都是相互吸引的，那么为什么没有吸引到一起？为了解决这个问题，安排了例题2例2、两物体质量都是1kg，相距1m，它们间的万有引力是多少？通过本题，让学生认识到一般物体间的引力极小，不用考虑。那么，质量很大的天体为什么没被吸引到一块？从而引出下节课题。4.课堂小结：本节课，从天体运动出发，通过推理证明，形成理性认识，再结合例题习题使学生的理性认识再反馈到具体事实。形成实践-理论-实践的认知循环，顺应了认知规律.。本共设计了很多问，能让学生想的尽量让学生想、能学生说的尽量让学生说、能让学生做的尽量让学生做，全面发展学生的各方面能力。再通过作业和探究性课题使学生的思维活动在时空上得以延续。5.布置作业：布置作业时刻意安排引入：万有引力、重力、向心力、三者的联系，通过引导学生对比结果，从中发现问题：万有引力与重力向心力的关系与区别，为下节知识的难点突破作好了铺垫。
人教版新课标高中物理必修2向心加速度说课稿
d．某物体沿直线向东运动，原来的速度是5m/s，2s后速度减小到3m/s，求2s内物体速度变化。④如何探究物体作匀速圆周运动时，在Δt时间内的速度变化？分析：有了同一直线上速度变化的铺垫后，讨论物体做匀速圆周运动速度的变化就比较自然了，为了给向心加速度方向的学习打好基础，可以通过小组协作，进一步完成下列思考题，使同学们认识到：时间间隔起短，速度变化的方向起接近半径方向。（多媒体屏幕投影）a．物体沿半径为1m的轨道做匀速圆周运动，线速度大小为，求1s内物体速度变化并画出1s内速度变化的示意图。b．分别求出上题中物体在0.5s、0.25s内速度变化并画出相应的示意图。由于没有办法直接利用实验来验证速度变化的方向，所以，我们采用提供思考题的方法，引导同学在合作学习、自主探究中完成。有了速度变化的研究为铺垫，加速度的方向问题就迎刃而解了。
人教版新课标高中物理必修2追寻守恒量—能量说课稿2篇
［小结］师：下面同学们概括总结本节所学的内容。请一个同学到黑板上总结，其他同学在笔记本上总结，然后请同学评价黑板上的小结内容。 （学生认真总结概括本节内容，并把自己这节课的体会写下来、比较黑板上的小结和自己的小结，看谁的更好，好在什么地方。） 生：本节课我们通过伽利略理想斜面实验，分析得出了能量以及动能和势能的概念，从能量的相互转化角度认识到，在动能和势能的相互转化过程中，能的总量保持不变，即能量是守恒的。通过这节课的学习，使我们建立起了守恒的思想。 点评：总结课堂内容，培养学生概括总结能力。 教师要放开，让学生自己总结所学内容，允许内容的顺序不同，从而构建他们自己的知识框架。［布置作业］课后讨论 P3“问题与练习”中的问题。［课外训练］以竖直上抛的小球为例说明小球的势能和动能的转化情况。在这个例子中是否存在着能的总量保持不变？
人教版新课标高中物理必修2宇宙航行说课稿2篇
了解了第一宇宙速度及其意义之后，继续提出问题，让学生思考：如果卫星的发射速度大于第一宇宙速度7.9km/s ，会出现什么情况呢？先让学生们大胆猜想，然后再向学生们介绍 卫星发射速度大于第一宇宙速度后的几种可能情况，引出第二宇宙速度和第三宇宙速度，让学生对第二、第三宇宙速度及其意义做定性了解。并通过演示Flash课件，帮助学生理解、加深学生印象。在学生对人造卫星的原理及发射卫星的速度条件有了初步了解后，接下来引导学生对卫星的运动规律作进一步的探索。实际上卫星并不是沿地表水平发射的，而是用火箭多次加速送到一定的高度的轨道后，再沿以地心为圆心的圆周的切线运行的。让学生继续深入思考：卫星在不同高度绕地球运行时的速度怎么求呢？将卫星送入低轨道和高轨道所需的速度都一样么？如果把不同轨道上的卫星绕地球的运动都看成是匀速圆周运动，引导学生利用已学的万有引力和圆周运动的相关知识，探究卫星绕地球的运行规律。

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
