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.
FAQ
1. PhysicsTutoring students and how to start fromPhysicsBenefit from tutoring?

The entire process usually only takes a few hours.
6. How long does the physics tutoring class last?
Most students and physics tutors will take 1.5 to 2 hours of tutoring. Firstly, the transportation and time arrangements of both parties will be better; secondly, students can learn more deeply, and at the same time, it will not be too burdensome for students.
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。

尖東中學物理補習：點解咁多人 Mechanics 卡死喺力學圖？
區嘅物理學生最常 stuck 嘅地方，唔係 syllabus 太難，而係冇人針對佢自己嘅 weak topic 度身教。學校老師要照顧成班 30+ 個學生，根本冇可能 individual 處理。一對一私補最大優勢就係呢度 — 由第一堂開始，導師會 diagnose 學生係咩 type 嘅錯處（粗心？concept 唔清？exam technique 唔識用？），然後針對性訓練。GETUTOR 過去兩年喺區物理科配對超過 450 宗 case，其中由原本 Level 2-3 升到 Level 4-5★ 嘅學生有約 67%*，平均堂數 8-12 堂。我哋平台超過 6,500 位實名認證導師，區物理科目前 280+ 位 5★ 評分導師可揀。試堂後付費，第一堂試完先決定，唔啱即轉。零風險。
尖東係九龍南半山位置，學生入讀嘅多數係油尖旺區嘅 Band 1 英中。根據 GETUTOR 後台 2024-2026 年油尖旺區物理配對紀錄，樣本約 318 宗*，當中有 36% 嘅家長一開口就講「個仔 Mechanics 完全唔得」。呢個比例比全港平均嘅 35% 略高啲*.
講真，尖東學生嘅 Mechanics 問題唔係佢哋蠢。佢哋多數係名校生，數學底子唔差。問題係物理嘅 free-body diagram 同數學嘅幾何題完全係兩個世界。我哋見過好多中四學生，攞起部 calculator 計到飛起，但畫起一條斜面上落滑塊嘅力學圖，連 normal force 嘅方向都搞唔清楚。
另外尖東嘅學生通病：操卷操得多，但係冇人教佢哋點樣由題目文字「翻譯」做圖。背公式 F=ma 佢哋識，但題目講「a block resting on an inclined plane」佢哋就 freeze。
導師 Quote：點解外面教佢哋學唔識
Mr. L（按導師私隱要求使用化名，導師資歷已獲 GETUTOR 平台認證）— 香港科技大學機械工程系畢業，DSE Physics 5**，現職全職補習導師。專補油尖旺區 Band 1 英中（例如九龍華仁、嘉諾撒聖瑪利）嘅中四至中六學生，年資 5 年。曾教超過 28 個 DSE 物理學生，當中 9 個攞 Level 5 或以上。教學風格主打「畫圖優先」，每堂頭十分鐘必畫一次 free-body diagram。
佢分享：「好多學生嚟到我度第一個問題就係：『點解我寫公式都計唔啱？』我嘅答案永遠係：『因為你冇畫圖。』Mechanics 嘅核心唔係公式，係力嘅方向同 component 拆解。我會要求學生畫三色筆：黑色畫物件、紅色畫已知力、藍色畫合力方向。一畫出嚟，個 free-body diagram 立即清晰。」
佢另一招：「由 inclined plane 開始教，唔係由 simple horizontal motion 教。因為斜面強迫學生 decompose vector，呢個係 Mechanics 真正嘅難關。如果學生連斜面個 mg 點拆 sin θ 同 cos θ 都搞唔掂，後面 circular motion、SHM 全部會 唔掂。」

GETUTOR 導師防伏貼士
講開 Mechanics 個防伏位，最大一個係好多補習社教學生用「公式代入法」。乜嘢叫公式代入法？就係見到題目有 mass、有 angle，就硬塞入 F=ma sin θ 試運氣。呢樣嘢喺中三程度勉強得，但去到 DSE 一定甩轆。
第二個 trap：mass 同 weight 分唔清。考評局近年特登出嘢考呢點。題目寫 “weight of an object on Earth is 50N”，學生即刻當 mass = 50kg，跟住跌落地獄。記住 weight = mg，mass = weight ÷ g。
第三個 trap：normal force 永遠垂直於接觸面，唔係永遠垂直向上。斜面上嘅 normal force 係沿住斜面嘅垂直方向，唔係指向天花板。呢個位每年 Mock 都有大量學生答錯。
進步時間線：尖東學生實際走勢
| time | 預期 |
|---|
| 第 1-2 堂 | 搵到弱項，畫圖手感建立 |
| 第 3-4 堂 | Mechanics 核心概念通晒 |
| 第 5-8 堂 | 校內測驗 Mechanics 部分明顯升 grade |
| 第 9-12 堂 | Mock 物理穩定企 Level 4 或以上 |
個案分享（已匿名處理）
一位油尖旺區 Band 1 英中嘅中五學生，配對前 Mock Physics 得 Level 3，主要因為 Mechanics 同 Electricity 兩部分不停跌分。經過 11 堂私補後，DSE 最終攞到 Level 5。學生家長 feedback 講：「Mr. L 教個仔由零開始畫 free-body diagram，依家佢自己睇題目都會自動拎筆畫圖，唔再憑感覺寫公式。」
FAQ
中四先補物理仲趕唔趕得切？
趕得切。中四 Mechanics 啱啱開始，呢個正係黃金時間。如果到中六先補，連基礎 free-body diagram 都未掌握，DSE 就好難 catch up。
尖東學生最常卡邊個 chapter？
係 Inclined Plane + Friction 結合題。尖東學生數學底子好，但物理係文字題拆 vector 嘅功夫，呢個唔係操數學能解決。
私補同大班最大分別係咩？
大班教統一進度，私補可以針對你個學校嘅課程節奏同 paper 風格度身教。尖東學生入嘅學校多數有自己嘅校本卷，私補可以對症下藥。
結語 + 配對
尖東學生補物理嘅關鍵唔係多操卷，係搵個願意陪你由 free-body diagram 畫起嘅導師。GETUTOR 油尖旺區物理配對平均 3.8 小時就有結果，試堂後繼續率 82%。想了解更多，可以入 GETUTOR 配對系統睇下有咩導師適合你。
