Physics is a popular subject for science as a DSE elective. If you master this subject, you will be successful in getting into the university of your dreams. To stand out in this public DSE exam, we offer the following 5 physics improvement tips.
1. It is necessary to understand the basic theory:
One of the easiest ways to learn physics is to master the basic theory. Without a foundation, it will be difficult to do any subsequent exercises. As the saying goes, everything is difficult at the beginning, so don’t be afraid. If you have any questions, feel free to ask the teacher.
Tips: Draft a Mind Map containing all knowledge points and concepts and associate them with the problem. In this way, you can see the whole picture of the theory and help with the basic principles that they actually want to ask for every complex question in mathematics.
2. Simplifying the problem:
physics is ahard to memorizesubject, but once simplified it becomes one of the most interesting and highest scoring subjects. Sometimes you'll encounter a tough problem, remember to break it down into simpler smaller components and attack each one one by one.
3. Create Flash Cards:
When you review various topics, write down the new words/concepts you encounter, and you can write some Principles and Laws into Flash Cards. In your spare time, you can also use these Flash Cards for quick memorization. Knowledge relies on memory and is built up layer by layer like a cake. Sometimes these Flash Cards also come in handy when you're stuck solving practice questions, so why not have one ready?
係,準備 Flash Cards 係物理科其中一個最有效嘅溫習工具。具體做法:每次上堂遇到新 concept、principle、formula 立即寫一張,正面寫概念名稱、背面寫定義同公式。每星期回顧一次,識嘅 cards 抽起、唔識嘅放埋一齊重複溫。GETUTOR 區物理導師中,超過 60% 都會建議學生用呢個方法,特別係 Physics / Chemistry 等需要記 formula 同 constant 嘅科目。Flash Cards 可以紙本、亦可以用 Anki / Quizlet 等 app(spaced repetition algorithm 比死記更有效)。我哋平台 6,500+ 實名認證導師全部 5★ 評分,試堂後付費,唔啱即時轉。第一堂試完先付款,零風險。區物理目前 280+ 位 5★ 導師可選,平均 24-48 小時內配對成功。
"Mathematics is the cornerstone of physics",Albert Einstein said it well. In order to understand physics well and perform well in physics exams, numeracy skills are essential. Students who do better in math generally do better in physics. This is a direct relationship, working hard in mathematics is also in physics.
5. Professional physics tutor
Are you studying hard but getting no results? Why not ask the teacher. You need a dedicatedPhysics tutor, Phy tutors can help you simplify concepts so that you can understand them effectively, and there are also many notes to take, so why not. An incompetent tutor will not be able to help you. Instead, it will make you think hard and puzzle you.GETUTORThere are countless professional physics tutors who can match you with a professional tutor who truly loves physics.Immediately assign PH tutoring teachers in Hong Kong.
Summarize
No matter how hard you work, the final result depends on your interest and practice level, but as long as you work hard, God will not let you down. A good teacher can accompany you to learn and grow. In the end, I hope you will achieve 5** in physics. Physics is not difficult. Nothing is difficult in this world, as long as you are willing. Maybe what you need is a hard worker and a good teacherguide.
In addition to DSE, we also have tutors from different academic systems to choose from, providing the widest range of tutoring services.其他學制,其他學制,其他學制 physcisThere are mentors.
Eight key points for answering Physics questions:
1. Remember the basic constants.
In physics, certain forces, such as the accelerating gravity on Earth, are often represented by the same number no matter where or how they are used. Remembering the most common constants (and their units) is the most basic knowledge point, because it is usually not given to candidates in exams, so candidates need to remember it themselves. Here are some of the most commonly used constants in physics:
- 重力加速度 g = 9.81 m/s²(地球表面標準值)
- 萬有引力常數 G = 6.67 × 10⁻¹¹ N·m²/kg²
- 真空中光速 c = 3.00 × 10⁸ m/s
- 真空中電子電量 e = 1.60 × 10⁻¹⁹ C
- 普朗克常數 h = 6.63 × 10⁻³⁴ J·s
- 阿伏伽德羅常數 N_A = 6.02 × 10²³ /mol
- Gravity (on earth): 9.81 meters/second2
- Speed of light: 3 × 108 meters/second
- Molar gas constant: 8.32 Joules/(mole × Kelvin)
- Avogadro's number: 6.02 × 1023 per mole
- Planck's Constant: 6.63 × 10-34 Joules × seconds
2.Remember the basic equations.
In addition to units, in physics, there are various equations. Forces act between many different forces in the universe, and their relationships are described by equations. Candidates only need to remember the contents of the equations and know how to use them. If the question does not provide certain information, the candidate can convert the equation to get a specific answer and then put it into the correct equation to calculate and solve the problem. Examples of some commonly used equations are:
- 牛頓第二定律:F = ma(力 = 質量 × 加速度)
- 動能公式:KE = ½mv²(質量乘速度平方除以二)
- 位能公式:PE = mgh(質量乘重力加速度乘高度)
- 歐姆定律:V = IR(電壓 = 電流 × 電阻)
- 波動公式:v = fλ(波速 = 頻率 × 波長)
- 萬有引力公式:F = Gm₁m₂/r²
- Velocity = Change in position/Change in time (v=dx/dt)
- Acceleration = Change in velocity/Change in time (a=dv/dt)
- Current velocity = Initial velocity + (Acceleration × time) (v=v0+a×t)
- Force = Mass × acceleration (F=m×a)
- Kinetic energy = (1/2)Mass × velocity2 (K=(1/2)m×v)
- Work = Displacement × force (W=d×F)
- Power = Change in work/Change in time (P=dW/dt)
- Momentum = Mass × velocity (p=m×v)
3.Study the derivation of basic equations.
Memorizing simple equations is one thing, understanding why they work is another.If you can, take the time to learn how each basic physics equation is derived. This gives you a clearer understanding of the relationships between equations and makes you a master of physics. Since you basically understand how an equation "works," you'll be able to use it more effectively rather than just memorizing it as a string of characters in your head.
- For example, let's look at a very simple equation:Acceleration = change in velocity/change in time,
- a = Delta(v)/Delta(t). Acceleration is the force that causes an object to change its speed. If an object is at time t 0 The initial speed is v 0, the final speed at time t is v, then it can be said that the object is moving from v 0Accelerate when changing to v. Acceleration cannot be instantaneous – it can happen quickly, but there will be some time lag between when the object travels at its initial velocity and when it reaches its final velocity. Therefore, it is concluded that:a = (v – v 0 /t-t 0 ) = Delta(v)/Delta(t).
4.Learn the mathematical skills needed to solve physics problems.
Mathematics is often called "the language of physics." Learning math well is a great way to improve your ability to solve physics problems. Some complex physics equations even require specialized mathematical skills (such as derivatives and integration) to solve. Here are just some keywords in mathematics that can help you solve physics problems, ordered by complexity:
- 基本算術:加、減、乘、除、分數、百分比
- 代數變換:解方程、移項、化簡,建立量與量之間嘅關係
- 三角函數:sin、cos、tan,用嚟分解力嘅 component
- 對數同指數:解決放射性衰變、波動方程嘅進階運算
- 微積分(HL only):導數 dy/dx 求 instantaneous rate,積分求 area under curve
- Pre-Algebra and Algebra (basic equations and "find the unknown" problems)
- Trigonometry (for force diagrams, rotation problems, and angular systems)
- Geometry (used to deal with problems such as area, volume, etc.)
- Pre-calculus and calculus (used to calculate derivatives and integrals of physical equations - usually advanced topics)
- Linear algebra (for calculations involving vectors - usually an advanced topic).
5.Focus on the important information in each question.
Physics questions often contain misleading "red herrings" that ignore unnecessary information as this will slow you down the ladder and complicate the problem. So, when reading a physics problem, you need to make sure that the piece of information given to you is correct and reasonable, and then identify the solution and write the equations needed to solve the problem. Then, assign each information point in the problem into the equation,
- 第一步:將題目讀兩次,畫出 free-body diagram 標出所有 force 同 vector direction
- 第二步:列出 given information(已知)同 required(未知),將 unit 統一為 SI 制式
- 第三步:從 formula sheet 揀啱對應 topic 嘅方程式,必要時組合多條公式
- 第四步:代入 numerical value 計算,保留 2-3 位有效數字,必要時轉換 unit
- 第五步:檢查答案合理性(方向 / 大小 / unit 是否符合 physical intuition)
Tips: Remember to adjust to appropriate variables.
- For example, suppose we need to find the acceleration experienced by a car as its speed changes over two seconds. If the car weighs 1,000 kg and starts moving at 9 m/s and ends at 22 m/s, we can say v 0 = 9 m/s, v = 22 m/s, m = 1,000 t = 2 s. As mentioned above, the standard acceleration equation is a = (v – v 0 /t-t 0 ). Note that the mass of the object is not taken into account here, so we can ignore the fact that the car weighs 1,000 kilograms.
- Therefore, we will solve as follows: a = (v – v 0 /t-t 0 ) = ((22 – 9)/(2 – 0)) = (13/2) = 6.5 m/s 2
Forgetting to mark your answers or using incorrect units are mistakes of the lowest order. To ensure you get the best possible score for any question you do, be sure to mark your answers with the correct units according to the type of information expressed. Listed below are some of the most commonly used common units of measurement in physics - please note that physics questions almost always use metric/SI measurements:
7.Don't forget the small details (like friction, resistance, etc.).
Physics problems are usuallyreal world model- That is, questions simplify how things actually work, making the situation easier for the reader to understand. However, this doesn't mean you can ignore an important tip, such as friction. It can be ignored unless the question states that it was intentionally left out of the question. If questions are not explicitly excluded and you have sufficient information, be sure to indicate them in your answer or ask your examiner for instructions.
- For example, suppose a problem asks you to find the acceleration of a 5-kg block along a smooth floor when it is pushed with a force of 50 Newtons. Since F = m × a, the answer seems to be as simple as solving for a in the equation 50 = 5 × a. However, in the real world, friction impedes an object's forward motion, effectively reducing the force with which it is pushed. Give the answer that excludes this friction force from the problem and gives the block accelerating slightly faster than it actually does.
8.Check your answers carefully.
A moderately difficult physics problem can easily involve a dozen mathematical calculations. Miscalculating any of these may result in your answer being incorrect, so pay close attention when doing your calculations.
Tips: If you have time, please check your answers carefully at the end.
- While simply redoing your calculations is one way to check that you answered a math question correctly, you can check your answers by using common sense to relate your questions to real life.
- For example, if you try to find the momentum (mass "Forward" direction is opposite). Therefore, if you get a negative answer, you may have made a mistake somewhere.

7. How many times a week should we have physics tutoring?
This depends on the student's current level, goals for improvement, and schedule. Most physics students arrange 2 to 3 periods of physics tutoring, but progress can be seen in every class.
8. How long will it take for me to make progress and see results?
It also depends on the student. Results from physics tutoring come over time and with student effort - on average, significant improvements are seen after 3 months. A major goal of physics tutoring is to provide students with the tools to succeed. Developing talent and learning takes time, but once learned, these habits will have a positive impact on students throughout their academic lives.
9. PhysicsWhere do private tutoring sessions take place?
Generally, physics tutoring will be conducted at the student's home. If it is not convenient, you can choose online tutoring such as ZOOM. When using ZOOM at home, students will feel comfortable and relaxed. In a familiar environment, their brains will be calmer and clearer, so they will be more open and receptive to physics tutoring and learning.
10. Do physics tutors from GETUTOR Hong Kong Tutors Association assign extra homework to students?
Physics tuition classes between students and physics tuition tutors are created exclusively to meet the needs of students. If a student needs extra practice, you can ask the tutor to schedule additional homework. But please note that homework is to consolidate what you have learned and deepen your understanding, not more is better.
11. PhysicsWill tutors contact parents?
We generally recommend that tutors contact parents. Physics tutors can notify parents about student progress and alert areas where your student may need additional help. The three-way cooperation between parents, tutors and teachers is the cornerstone for students to achieve their ideal goals.
12. How can I improve the tutoring effectiveness of physics tutoring for students?
最大化物理補習效益嘅 3 大關鍵:1)每堂後立即重做導師講過嘅 example,等 concept 真正入腦,唔好等到考試前先操;2)保持每星期至少 1 次穩定 frequency,停三星期再補等於從頭嚟過;3)家長定期同導師同步學校進度(測驗範圍、學校老師重點),讓私補同學校教學形成 reinforcement loop。GETUTOR 過去兩年喺區物理科配對嘅 case 入面,有跟足呢三個 rule 嘅學生平均喺 8 堂內成績提升 12-18 分*。我哋平台超過 6,500 位實名認證導師全部 5★ 評分,試堂後付費,唔啱可以即時轉到啱為止。

坑口物理補習:Mechanics 同 Electricity 兩座大山,邊個先補?
坑口嘅 DSE 物理生最痛苦:Year 5 上學期 mock 連 Force Diagram 都畫錯
坑口、寶琳呢一帶,住嗰啲家庭多數係將軍澳新市鎮第一批搬入嚟嘅,個小朋友讀景嶺書院、迦密主恩、香港華人基督教聯會(坑口)、聖公會將軍澳基德小學嘅升中學生。讀 DSE Physics 嘅學生,最大噩夢通常係 F.5 開始 — 點解 force 同 acceleration 嘅關係明明明白,一畫 free-body diagram 就甩晒轆。
根據 GETUTOR 後台 2024-2026 年將軍澳(將軍澳、寶琳、坑口)DSE Physics 配對紀錄,樣本約 142 宗*,平均配對時間 4.2 小時。當中要補 Mechanics 嘅佔 36%、要補 Electricity 嘅佔 27%。呢兩座大山加埋已經 63% 配對需求。
另一個我哋觀察到嘅現象:將軍澳區嘅試堂後繼續率係 82%*,比平均高,反映呢區家長一旦搵到啱嘅老師會 stick to it。
導師 Quote:Mechanics 點解咁難?因為 Free-body Diagram 一畫錯,後面全晒 0 分
Mr. T(按導師私隱要求使用化名,導師資歷已獲 GETUTOR 平台認證)— 香港理工大學工程學士(主修機械工程),DSE Physics 5**,曾任將軍澳一所補習社 DSE Physics 兼職導師兩年,之後轉全職私補。教學年資 5 年,主補將軍澳、寶琳、坑口、康城一帶 DSE Physics。累計教過超過 30 個 Physics 學生,當中 11 個攞 Level 5* 或以上。
Mr. T 指出:「將軍澳嘅學生我教得最多。Mechanics 同 Electricity 兩座山一定要逐個攻,唔好兩個一齊撈埋。我建議由 Mechanics 開始,因為佢係物理嘅地基。如果你連 free-body diagram 都畫唔啱,Electricity 嗰啲 circuit 你死定。教 Mechanics 我用一個方法叫『3-axis check』:每次畫完 free-body diagram,學生一定要 check 三件事:第一,所有 force 係咪都由物體本身出發?第二,有冇遺漏 normal reaction?第三,friction 嘅方向有冇畫返轉?呢三步做齊,全港 DSE Physics Level 4 以下嘅學生即刻升到 Level 4。」
呢套教法源自 GETUTOR 內部物理導師培訓,老師都係從 Engineering 嘅實際應用 reverse engineer 出嚟。

GETUTOR 導師防伏貼士:DSE Physics 三大常踩 trap
第一,學生最常見誤解係:分唔清 mass 同 weight。Mass 係 scalar、單位 kg、永遠唔變;Weight 係 vector、單位 N、會隨 g 嘅 location 變。考評局年年都試圖 set 呢個 trap,例如 spaceship、moon scenario,學生答錯就死。
第二,2024 改制之後,Paper 1A 嘅 short question 回歸(似當年會考),意味住 step-by-step calculation 重要過寫長 essay。記住:每行算式寫齊單位,多寫一行算式可以攞額外 1 分。
第三,Electricity 嘅 circuit 計算。串聯 vs 並聯,學生最常錯嘅地方係:搵 total resistance 用錯公式。Mr. T 嘅 trick 係:「先畫 simplified circuit,再代公式」,唔好直接望住複雜 circuit 諗。
進步時間線

個案分享(已匿名處理)
一位坑口某 Band 1 英中嘅 F.5 學生,補前 mock Physics 得 Level 3,主要弱項係 Mechanics。經過 12 堂私補(每堂 1.5 鐘),DSE 最終攞 Level 5。導師主要用 free-body diagram 訓練 + circuit simplification 技巧。
FAQ
F.5 開始補 Physics 仲趕唔趕得切?
趕得切。如果你 Mechanics 基礎 OK,F.5 開始 14-16 堂可以由 Level 3 升到 Level 5。基礎完全唔穩就要更多堂。
坑口學生最常卡邊個 topic?
根據紀錄,Mechanics(佔 36%)同 Electricity(佔 27%)係兩大重災區。呢兩個 topic 加埋已經 63%。
Physics 私補一定要搵工程系嗎?
工程或物理系都可以。但工程系老師通常 free-body diagram 同 circuit 教得更扎實,因為佢哋日常 work 都用緊。
