6. Core Topic Areas: Mechanics, Fields and Waves | 核心专题：力学、场与波
The core syllabus is built around a small number of interlinked physical themes. Mechanics encompasses kinematics, Newton’s laws, energy concepts, circular motion, and simple harmonic motion (SHM). Students must be fluent with equations such as
v = u + at
and
s = ut + ½at²
, as well as the calculus forms for SHM.

Gravitational and electric fields are treated in parallel, highlighting the inverse-square law. Key formulae include
F = Gm₁m₂/r²
and
E = kQ/r²
. Students learn to define potential and equipotential surfaces, and to combine field concepts in both Paper 1 and Paper 2 contexts.
引力场和电场被平行处理，突出了平方反比定律。关键公式包括 F = Gm₁m₂/r² 和 E = kQ/r²。学生学习定义势能与等势面，并在试卷一和试卷二的情境中综合运用场概念。
Waves and optics require understanding of interference, diffraction, polarisation, and the Doppler effect. The wave equation
v = fλ
is foundational, but students must also handle superposition with phase differences expressed in radians.

τ = RC
. Capacitors and their energy storage are directly linked to electric field theory.
电学与电路包括基尔霍夫定律、内阻、分压器以及对时间常数 τ = RC 的RC电路分析。电容器及其能量储存直接与电场理论相关联。
Modern physics introduces photons, the photoelectric effect, wave-particle duality, and energy levels in atoms. The de Broglie wavelength
λ = h/p
and the photoelectric equation
Ek max = hf – Φ
are central. Radioactive decay, nuclear binding energy, and the basics of particle physics complete this section, setting the stage for Paper 2 depths.

8. Advanced Topics: Relativity, Medical Physics and Beyond | 进阶专题：相对论、医学物理等
The advanced topics select a subset from the core and extend them significantly, while also introducing entirely new areas. Special relativity, for example, requires students to handle time dilation, length contraction, and the invariance of the space-time interval. The Lorentz factor
γ = 1/√(1 – v²/c²)
is used extensively.
进阶专题从核心内容中选取了一部分并显著扩展，同时也引入了全新的领域。例如，狭义相对论要求学生处理时间膨胀、长度收缩以及时空间隔的不变性。洛伦兹因子 γ = 1/√(1 – v²/c²) 被广泛使用。
Medical physics, a popular option, covers the production and detection of X-rays, ultrasound imaging, and nuclear medicine. The concept of acoustic impedance
Z = ρc
and the half-value layer for radiation attenuation are key quantitative ideas. Other options may delve into particle physics or astrophysics, all demanding high-level analytical skills.
医学物理是一个受欢迎的选修方向，涵盖X射线的产生与探测、超声成像以及核医学。声阻抗 Z = ρc 和辐射衰减的半值层等概念是关键的量化思想。其他选修可能深入粒子物理或天体物理，所有这些都需要高水平的分析能力。
9. Mathematical Requirements | 数学要求
Pre-U Physics assumes a strong foundation in mathematics, roughly corresponding to the skills acquired in an A Level Mathematics course. Candidates are expected to use calculus fluently for deriving and applying relationships, such as velocity from displacement in SHM or the charging current in an RC circuit.
Pre-U物理假设学生具备坚实的数学基础，大致相当于A Level数学课程所掌握的技能。考生需要熟练使用微积分来推导和应用关系，例如从简谐运动的位移求速度，或者RC电路中的充电电流。
Other essential mathematical tools include the use of exponentials and logarithms (e.g., radioactive decay N = N₀e-λt), trigonometric functions for wave superposition, vector addition and resolution, and the manipulation of equations involving small-angle approximations where sinθ ≈ θ. Error propagation and analysis of uncertainties are tested explicitly in Paper 1 Section A.
其他重要的数学工具包括指数与对数的使用（如放射性衰变 N = N₀e-λt）、用于波叠加的三角函数、矢量相加与分解，以及涉及小角度近似 sinθ ≈ θ 的方程处理。误差传播和不确定性分析在试卷一的A部分有明确考查。
10. Practical Skills and Experimental Techniques | 实验技能与技术
Although the written papers carry the majority of the marks, practical competency is integral. The Personal Investigation is the primary vehicle for assessing skills such as instrument selection, measurement techniques, data logging, and statistical analysis.
尽管书面试卷占据了大部分分数，但实践能力是不可或缺的。个人调查是评估诸如仪器选择、测量技术、数据记录和统计分析等技能的主要载体。
In addition, Paper 1 Section A may include questions based on standard laboratory experiments, expecting familiarity with instruments like vernier callipers, micrometers, oscilloscopes, and electrical meters. Understanding how to reduce random and systematic errors, and the distinction between accuracy and precision, is essential for both the exam and the investigation.
此外，试卷一的A部分可能包含基于标准实验室实验的问题，期望学生熟悉游标卡尺、千分尺、示波器和电表等仪器。理解如何减少随机误差和系统误差，以及准确度与精确度之间的区别，对考试和调查都至关重要。
11. Using the Syllabus for Effective Revision | 高效复习：如何利用大纲
The official Cambridge syllabus document is your most valuable resource. It lists every learning outcome with the command words “define”, “describe”, “explain”, or “derive”. Using this as a checklist ensures no topic is missed. Active revision should involve practice of long, synoptic questions under timed conditions.
官方的剑桥大纲文件是你最宝贵的资源。它用“定义”、“描述”、“解释”或“推导”等指令词列出了每一个学习成果。将此作为检查清单可确保不遗漏任何主题。有效的复习应包括在计时条件下练习长篇幅的综合问题。
Because Papers 1 and 2 are linear and cover the full two years’ content, creating thematic links between core and advanced topics is a powerful revision strategy. For example, study universal gravitation alongside Coulomb’s law to appreciate the parallels, then extend to potential theory. The syllabus structure itself is a guide to these connections.
由于试卷一和二是线性的，涵盖了整个两年的内容，在核心与进阶主题之间建立主题联系是一种强大的复习策略。例如，将万有引力与库仑定律一起学习以体会其相似性，然后扩展到势能理论。大纲结构本身就是这些联系的指南。
