人教版新课标高中物理必修2能量守恒定律与能源教案2篇
世界能源问题的解决途径是什么?能源，是人类敕以生存和进行生产的不可缺少的资源．近年来，随着生产力的发展和能源消费的增长．能源问题已被列为世界上研究的重大问题之一．解决世界能源问题的根本途径，主要有两个方面：其一是广泛开源，其二是认真节流．所谓开源，就是积极开发和利用各种能源．在继续加紧石油勘探和寻找新的石油产地的同时，积极开发丰富的煤炭资源，还要大力开发水能，生物能等常规能源，加强核能、太阳能，风能、沼气，海洋能，地热能以及其他各种新能源的研究和利用，从而不断扩大人类的能源资源的种类和来源．所谓节流，就是要大力提倡节约能源．节能是世界上许多国家关心和研究的重要课题，甚至有人把节能称为世界的“第五大能源”，与煤、石油和天然气、水能、核能等并列．在节能方面，在有计划地控制人口增长的同时，重点要发挥先进科学技术的优势，提高各国的能源利用效率．
人教版新课标高中物理必修2曲线运动教案2篇
1、教师先演示投影：把小钢珠放在黑墨水瓶盖里转一下（内有一点点墨水），再放在半圆形有机玻璃轨道上运动并飞出，让钢珠在白纸上留下痕迹，同样在3/5半圆周，4/5半圆周上运动飞出，让学生猜测飞出方向由什么特点？（有机玻璃板说明：厚约5毫米，略小于小钢珠直径，圆弧半径15厘米，MN边稍长些，以便过MN做直线，根据半径大小确定圆心O位置。）学生猜想：切线方向师：已知圆弧半径为15厘米。如何验证？请用几何方法作图验证。生：标出飞出点和圆心，做圆心和飞出点的连线，用量角尺量出该连线和飞出轨迹直线的夹角，是否90度。2、再分组实验，提醒同桌配合，小心钢珠滚跑。实验完毕，要求作图验证，并互相讨论交流。3、交流和结论：师：要引导学生得出正确的科学结论：“圆周运动的物体的速度方向为该点的切线方向”，而不能直接得出“曲线运动的的物体速度方向为该点的切线方向”。
人教版新课标高中物理必修2向心加速度教案2篇
1．教材在学生的原有加速度概念的基础上来讨论“匀速圆周运动速度变化快慢”的问题，让学生知道向心加速度能够表示匀速圆周运动物体速度变化的快慢究竟是怎么一回事。2．教材把向心加速度安排在线速度和角速度知识之后，使学生对描述匀速圆周运动的几个物理量有一个大致的了解。3．教材从了解运动的规律过渡到了解力跟运动关系的规律；把向心加速度放在向心力之前，从运动学的角度来学习向心加速度。4．教材为了培养学生“用事实说话”的“态度”，让一切论述都合乎逻辑，改变了过去从向心力推导向心加速度的教学方式。1．采用理论、实验、体验相结合的教学安排。2．教师启发引导，学生自主阅读、思考，讨论、交流。知识与技能1．会作矢量图表示速度的变化量与速度之间的关系。2．加深理解加速度与速度、速度变化量的区别。3．体会匀速圆周运动向心加速度方向的分析方法。4．知道向心加速度的公式也适用于变速圆周运动；知道变速圆周运动的向心加速度的方向。

区分宾语从句、定于从句和状语从句宾语从句和状语从句，都叫做主从复合句。宾语从句主要是中考必考的，是初中阶段必掌握的从句，宾语从句主要是掌握三要素，所谓宾语从句，就是宾语在主从复合句当中充当宾语的一个句子，叫做宾语从句。主句的谓语动词是及物动词，后面如果是词或者是短语的话，是简单句，如果是句子的话，肯定是宾语从句。I know that he good at English.就是宾语从句，三要素，一要素是要注意连词，连词一共学了三类连词，一类连词是that口语当中可以省略，就像刚才说的那一句，I hear he is good at English.还有疑问代词、疑问副词，how where when，疑问代词、疑问副词。还有一类连词weather是否的意思，不是状语从句当中的如果，这一定要和如果区分开，这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序，要用陈述举语序。比如说你家有几口人，我们都说How many people are there in you family?但是这是简单句，一旦说成宾语从句，你可以告诉我你家有几口人吗？Could you tell me how many people there are in you family ?
