SPM于2021年开始第一年以KSSM课程考试,所以本频道即将把每一章做成Revision Video,方便各位学生学习。由于做video需要时间,如果各位要先看一看各个章节的内容,可以先对应回2020 SPM Revision. 对应的章节如下: Form 4 Chapter 1: (已完成) Form 4 Chapter 2: (已完成) Form 4 Chapter 3: (已完成) Form 4 Chapter 4: (已完成) Form 4 Chapter 5: (已完成) Form 4 Chapter 6: (已完成) Form 5 Chapter 1:(已完成) Form 5 Chapter 2: (已完成) Form 5 Chapter 3: (已完成) Form 5 Chapter 4: kzbin.info/www/bejne/r6eol4J-jd51ZsU Form 5 Chapter 5: kzbin.info/www/bejne/o3LNiYqkfqdnpNk & kzbin.info/www/bejne/oHTXlomjpNFgl5Y & kzbin.info/www/bejne/eouzYalqdpp_ma8 Form 5 Chapter 6: kzbin.info/www/bejne/oomqYXprdrOqjbs Form 5 Chapter 7: 新课程
那个是acceleration的大小,所以我写 negative 4。 不过,deceleration or acceleration 其实是要看方向的。 例如: t=20 s to 25 s, acceleration 是 negative 2, 但是他是accelerate at the negative direction 反方向加速。

请问Gravity and Vertical Motion due to Gravity是属于F4 KSSM PHY的Chapter2吗?还是Chapter3呢?
@NorthPhysics3 жыл бұрын
Vertical motion due to gravity 是Form 4 Chp 2的... 星球之间或者地球和satellite 之间的万有引力是Form 4 Chp 3的,可以看这里: kzbin.info/www/bejne/rpayeqN7bdFmmMk

老师,想要问16:34 那里的question 7 为什么是拿30 x 0.4 而不是拿 5 x 0.4
