1、名师精编优秀教案人教版九年级物理第 15 章、功和机械能复习课学案学习过程：一、知识点巩固1、做功的两个必要因素、.练习：（分析下列事例，是否做功。）马拉车搬而未起提着水桶水平前进光滑的水平冰面上滑动的冰块2、功的计算公式：，各物理量的单位分别是：练习、课本 P107图 15.21 中，人的拉力做功分别是W1，W2，W3。3、简述什么叫有用功、额外功、总功、机械效率事例分析：分析哪些是有用功、额外功、总功1用桶和绳子从井口拔一桶水（G桶=20N、G绳=10N、G满水=100N,h井深=10m）W有=,W额=,W总=.。2桶掉到井里了，从井里捞出桶时，桶里有半桶水）W有=,W额=,W总=.。4

2、功率：功率是用来表示的物理量，叫做名师精编优秀教案功率，公式：单位：练习：甲乙二人爬杆比赛，请添加相关条件，比较功率大小。5、什么叫动能，动能大小的影响因素是。什么叫做势能（重力势能、弹性势能）它们的影响因素分别是练习：洒水车沿水平地面匀速前进洒水过程中，动能，因为。喜鹊与麻雀在空中飞行，如果它们的动能相等，那么麻雀比喜鹊飞的，如果它们重力势能相等，那么麻雀比喜鹊飞的。6、机械能在数值上等于之和。分析：滾摆在上升过程中，质量，速度，动能，质量，高度，重力势能，在此过程中能转换为能，滾摆在下降过程中呢？二、知识结构梳理。文档编码:CY6R2N9T8U10 HX8Z4K8M10G2 ZD2I10I
