章节摘录

版权页：   插图：   弹性、非弹性和完全非弹性碰撞 1. In an elastic coil&ion, kinetic energy is conserved. Whatever kinetic energy isspent deforming the objects as they collide is completely recovered as they sep-arate (the energy is only temporarily stored as a compression of the objects). 2. In inelastic collisions, kinetic energy is not conserved (some is used toproduce heat, sound, or permanently deform the objects, all of which are non-conservative processes). 3. In a totally inelastic collision, kinetic energy is also not conserved, and the twoobjects remain stuck together after the collision. 碰撞问题的解法 First, you must decide whether the collision is elastic or inelastic. If the problemsays that the two particles end up stuck together, it is by definition totally inelastic.Otherwise, the problem generally tells you whether the collision is elastic or (equiv-alently) whether kinetic energy is conserved. When the collision is elastic, you can construct equations based on the fact thatboth linear momentum and kinetic energy must be conserved. If the collision isinelastic, you can use only the conservation of linear momentum. The following are extra problem-solving tips: 1. If the collision is totally inelastic, the objects share a common.final velocity(because they are stuck together). 2. Remember that momentum is a vector, so if the collision occurs in more thanone dimension, the conservation of the momentum vector will be equivalentto a set of two or three one-dimensional equations. 3. If the problem allo~vs you to calculate the change in kinetic energy during thecollision, you can use a modified conservation of energy equation (such as△KE = KEfr - KE0) to solve an inelastic collision. 4. When you think of a situation where linear momentum is conserved, you prob-ably think of a collision involving "contact forces. However, momentum is con-served even when forces act at a distance (such as gravitational forces orelectrostatic forces), as long as there are no net external forces. For example,the momentum of a system of planets, which attract each other gravitationally,is conserved.

•   对于学习AP物理很有帮助，书是正品，质量很好！
•   物理C名不虚传，其要求早已超越了国内一般的高考水平，大致介于自主招生难度和物理竞赛试题难度之间^^表示压力很大……建议先学一点微积分再看这本书，里边（特别是电磁学）对于高数的要求还是很高的
•   最新版的，看起来不错 有些小标题物理名词还有中文标注 不错
•   此书讲解较细，实用性很强。
•   刚开始学习，希望对考试有帮助。
•   Just as great as it should be! Incredibly smart express, knowing that two books purchased at different websites shall be delivered to the same place, reached my place for no more than two days! Incredible!
•   给孩子买的，总体感觉不错
•   比原版的还好。。。纸质不错，几乎全英文
•   希望学有所成
•   非常有用、包装的蛮漂亮、好！
•   barron系列的书很喜欢
•   书的质量非常好，不仅可以供学习和复习，作为一部优秀作品收藏也可以的?
•   学ap的不二选择！商品是正版特别好
•   相比princeton还是有难度，有些讲解没有很细致
•   里面有错误，第二章里就有多达两项错误，后面还没有看到。
•   书，儿子看来，质量很不错。
•   孩子认为书写的浅显易懂
•   书质量很好，物流和服务都很好，到现在没有发现任何问题，还会继续光顾。
•   还不知怎样，还没有使用
•   给孩子上国际中学用的，很好
•   书什么的，只要不窝不坏可以读就行了，况且这个价也比较值了，送的也很快。
