高三一轮复习每日一练|动量守恒定律

高三一轮复习每日一练｜动量守恒定律

高三一轮复习每日一练｜第 65 天
今日练习：动量守恒定律
动量守恒定律是动量模块的核心主干知识，也是高考计算题高频考点，判断守恒条件是做题第一步，一旦判断失误，整道题都会跑偏。
本次练习分为两大题型：
▪️题型一：判断系统动量是否守恒
▪️题型二：动量守恒定律的初步应用
重点掌握动量守恒的三大条件：系统合外力为零、某一方向合外力为零、内力远大于外力。先学会准确判定系统、分清研究过程，再规范列式，打好动量守恒综合题的基础。一轮复习稳扎稳打，把基础逻辑练到位。#高中物理#一轮复习#每日一练#高考提分#自主学习选择性必修一#动量#动量守恒定律#判断系统动量是否守恒
