我諗你係指Kinetic theory of ideal gas嗰proof
其實2016開始已經cut左嗰proof,
Centripetal acceleration
Kinetic theory of ideal gas
呢兩個proof已經cut左
如果你想知點proof,我都可以再post詳細少少嘅proof

我未係正職老師,
搵教席都係識人緊要d
利申:好多學校物理老師都識
你有興趣,留tg,有時學校搵我教班,
我都要搵人幫手

主要有4 part
Rutherford model
- description of model
- failure to explain some phenomenon
Photoelectric effect
- why particle theory of light should be used instead of wave theory? (有3個experiment results wave theory解釋唔到)
- formulaSSSSSSSS
(KEmax=e Vs = hf - phi)
( light intensity = (#photon/time)(hf)/area ) 呢題都最好當一條式去記
Bohr model
- postulates
- relation of orbit radius of election and energy with quantum number n
(其實計數機constant入面係有Bohr radius ,嗰symbol係a0)
- 點去計數
- transition of energy level can be done by
Absorbing/emitting photon or inelastic collision with electron
wave-particle duality
- equation of wavelength , energy and momentum of wave and particle
- experiment evidence of particle nature of light and wave nature of particle
Nano-scale
- water-repelling vs water-attracting in cleaning
- 計數比較簡單,但要小心
- TEM and STM

可唔可以分析elective簡邊兩個好
想要穩定9成以上

會拉curve 太多人簡e2 e3無優勢

Medical 原意係比能力差嘅學生去讀,所以出得出較簡單,雖然好似好多野要記,但事實上大部份都唔洗記
結論:易拿分
Energy 雖然內容上比較易明,但對考得比較tricky
2017年有一題MC cancel左,大約一半人都答錯。
2017年LQ其中文字題又係少人拿到分。
頭幾年就出過一題,香港適合發展那一個可再生能源,再加解釋。答案係風能,解釋就係香港有季候風。
呢類型問題比較難拿分。
結論: 易讀,但難高分
