1、名师精编优秀教案1.6 电势差与电场强度的关系一【教材分析】本节内容主要是研究电势差与电场强度之间的关系，虽然前者是标量，后者是矢量，但通过静电力做功在两者之间建立了联系。本节内容的重点是匀强电场中两点间的电势差等于电场强度与这两点沿电场方向的距离的乘积。二【教学目标】1、知识与技能定性把握电势差与电场强度的关系，理解匀强电场中电势差与电场强度的定量关系。2、过程与方法通过对匀强电场中电势差和电场强度的定性、定量关系的学习，培养学生的分析、解决问题的能力3、情感态度与价值观从不同角度认识电场、分析寻找物理量之间的内在联系，培养对物理学科的兴趣、坚定思考探索物理的的信念，领略物理方法的奥妙，体会
2、物理科学的力量。三【重点、难点】重点：匀强电场中电势差与电场强度的关系难点：对公式 U=E d 中 d 的理解及公式的正确运用(d为沿场强方向两点所在等势面的距离)四【学情分析】电场强度和电势都是描述电场性质的物理量，两者从不同的角度对电场性质进行描述。对于这节课的讲解，只要求让学生定性了解电势差与电场强度的关系就可以了。对于匀强电场，在讲授时，只要求学生了解它们的定量关系式，即在匀强电场中推导出电场强度与电势差的关系公式，并通过公式变形，用比值的方法指出电场强度在数值上等于沿电场方向每单位距离上降低的电势。通过分析，培养学生的分析能力。五【教学方法】讲授法、推理法、归纳法六【课前准备】多媒体
3、辅助教学设备、练习资料七【课时安排】一课时八教学过程（一）预习检查、总结疑惑问题：名师精编优秀教案电场的两个基本性质是什么？答：电场的两个基本性质：电场的力的性质（）（二）情景引入、展示目标电场的能的性质（电势能、电势、电势差）电势电场强度E？电势差（）电场力（）电势能的变化等于电场力所做的功（）电场强度描述电场的力的性质，而电势描述电场的能的性质，且电势差跟电场力做功相联系，那么电场强度E和电势差U又有什么关系呢？倾听、思考、回答培养学生的思维能力、【新课教学】：一、电场强度与电势差的关系通过匀强电场的例子来推算U和 E之间的关系。如图所示：表示某一匀强电场的等势面和电场线。沿场强方向把正电
