📚 AQA International A-Level Physics 9630: Complete A2 Scheme of Work | AQA 国际A-Level物理 9630：完整 A2 教学大纲指南
The AQA International A-Level Physics (9630) A2 scheme of work is the structured second-year teaching plan that builds directly on the foundations laid in AS. This guide maps the entire A2 syllabus — Further Mechanics, Thermal Physics, Fields, Capacitance, Magnetism, Nuclear Physics and the optional topic — into a clear week-by-week structure, with required practicals, mathematical demands and examination strategy integrated throughout.
AQA 国际A-Level物理（9630）A2教学大纲是第二学年的结构化教学计划，直接建立在AS阶段所奠定的基础之上。本指南将完整的A2教学大纲——进阶力学、热物理、场、电容、磁学、核物理及选修专题——拆解为清晰的周次教学结构，并将必做实验、数学要求和考试策略贯穿其中。
1. A2 Scheme of Work Overview | A2 教学大纲总览
The A2 year is typically planned across 40 teaching weeks. The mandatory content occupies sections 6–8 of the specification (Further Mechanics, Thermal Physics, Fields and Nuclear Physics), with one optional topic from section 10 delivered in the final term.
A2学年通常按40个教学周规划。必修内容涵盖考纲第6–8部分（进阶力学、热物理、场与核物理），并在最后一个学期从第10部分中选择一门选修专题进行教学。
The recommended time allocation for each block is summarised below. This schedule assumes approximately five teaching periods per week, with two-hour practical sessions included fortnightly.
各板块的建议课时分配如下表所示。该时间表假定每周约五个教学课时，并每隔一周安排两小时的实验课。
| Specification Section | Topic | Suggested Weeks |
| 6 | Further Mechanics | 6 |
| 7 | Thermal Physics | 4 |
| 8 | Fields and Capacitance | 9 |
| 9 | Nuclear Physics | 4 |
| 10 | Optional Topic | 5 |
| — | Required Practicals and Revision | 12 |
2. Transition from AS to A2 | 从AS到A2的关键过渡
The jump from AS to A2 is substantial: mathematical demand rises sharply, concepts become more abstract, and questions increasingly combine multiple topics in a single problem. Students must be comfortable manipulating exponentials and logarithms before studying radioactive decay and capacitor discharge.
从AS到A2的跨度很大：数学要求显著提高，概念更加抽象，题目越来越倾向于将多个知识点结合在同一道问题中。学生在学习放射性衰变和电容器放电之前，必须熟练掌握指数与对数的运算。
Another major shift is the move from mechanical, visualisable systems to field-based reasoning. Gravitational, electric and magnetic fields require students to think in terms of action at a distance and to interpret field lines, equipotentials and potentials fluently.
另一个重大转变是从可直观理解的力学系统转向基于场论的推理。引力场、电场和磁场要求学生以超距作用的思维去理解问题，并能熟练解读场线、等势面与电势。
Practical skills also become more demanding: students are expected to design experiments, evaluate uncertainties and use error analysis to justify conclusions, all of which contribute directly to Paper 3 assessment.
实验技能的要求也更高：学生需要自行设计实验、评估不确定度，并运用误差分析来论证结论，这些都将直接影响Paper 3的评分。
3. Further Mechanics (Weeks 1–6) | 进阶力学（第1–6周）
This block opens with circular motion. Angular speed ω relates to period and frequency by the equations below, and centripetal acceleration arises whenever the direction of velocity changes continuously.
本板块以圆周运动开篇。角速度ω通过下列方程与周期和频率关联，只要速度方向连续改变，就会产生向心加速度。
ω = 2π/T = 2πf , v = rω , a = v²/r = ω²r , F = mv²/r = mω²r
The centripetal force is always directed towards the centre of the circle. Common A2 examples include the conical pendulum, cars on banked tracks and satellites in orbit, where gravity supplies the required centripetal force.
向心力始终指向圆心。A2常见例题包括圆锥摆、倾斜轨道上的汽车以及轨道卫星——后者由万有引力提供所需的向心力。
Simple harmonic motion (SHM) is defined by the restoring acceleration being proportional to displacement and opposite in direction:
简谐运动（SHM）的定义特征是恢复加速度与位移成正比且方向相反：
a = −ω²x , x = A cos(ωt) , v = ±ω√(A² − x²)
For a mass–spring system and a simple pendulum, the periods are respectively T = 2π√(m/k) and T = 2π√(L/g). Students should verify both experimentally and use graphical methods such as plotting T² against mass or length to determine k or g.
对于弹簧振子和单摆，周期分别为 T = 2π√(m/k) 和 T = 2π√(L/g)。学生应通过实验验证二者，并利用作图法——例如绘制 T² 对质量或长度的图像——来求解 k 或 g。
Damping reduces amplitude over time; light damping maintains near-constant period, while heavy damping prevents oscillation entirely. Resonance occurs when the driving frequency equals the natural frequency, producing maximum amplitude — engineers must avoid this when designing bridges and buildings.
阻尼会随时间减小振幅；轻阻尼使周期基本保持不变，而强阻尼则会完全阻止振荡。当驱动频率等于固有频率时发生共振，振幅达到最大——工程师在设计桥梁和建筑物时必须避免这一现象。
4. Thermal Physics (Weeks 7–10) | 热物理（第7–10周）
Thermal physics begins with internal energy as the sum of the random kinetic energies and potential energies of the molecules in a substance. Heating that causes a temperature change involves specific heat capacity, while heating at constant temperature during a phase change involves specific latent heat:
热物理首先介绍内能——物体内部分子随机动能与势能的总和。引起温度变化的热量涉及比热容，而在相变过程中温度保持不变所吸收或释放的热量则涉及比潜热：
E = mcΔθ , E = mL
The ideal gas law links macroscopic state variables. In A2 you must also use the Boltzmann constant form pV = NkT, where N is the number of molecules.
理想气体状态方程联系了宏观状态参量。在A2阶段，还必须使用玻尔兹曼常数的形式 pV = NkT，其中 N 为分子数目。
pV = nRT = NkT
Kinetic theory connects the microscopic motion of molecules to measurable pressure. The key result is that pressure relates to the mean square speed of the molecules:
分子动理论将分子的微观运动与可测量的压强联系起来，其关键结果是压强与分子的均方速率相关：
pV = ⅓Nm⟨c²⟩ , and therefore ½m⟨c²⟩ = ³⁄₂kT
This shows that absolute temperature is proportional to the mean kinetic energy of gas molecules. Students should practise converting between root-mean-square speed and temperature, and account qualitatively for deviations from ideal behaviour at high pressure and low temperature.
这表明绝对温度与气体分子的平均平动动能成正比。学生应练习在均方根速率与温度之间进行换算，并能够定性解释在高压和低温条件下实际气体偏离理想行为的原因。
5. Gravitational and Electric Fields (Weeks 11–15) | 引力场与电场（第11–15周）
Both gravitational and electric fields are inverse-square law fields. The gravitational force and the Coulomb force are mathematically analogous, and the treatment of field strength and potential mirrors between the two topics — but with one critical difference: gravity only attracts, while electric charges attract or repel.
引力场与电场都是平方反比定律场。万有引力与库仑力在数学上高度相似，二者在场强与电势的处理方式上相互对应——但存在一个关键差异：引力只吸引，而电荷可以吸引或排斥。
g = GM/r² , V_g = −GM/r , E = Q/(4πε₀r²) , V_e = Q/(4πε₀r)
Gravitational potential is defined as zero at infinity and is negative inside a field, whereas the conventions for electric potential depend on the sign of the source charge. Field strength is the negative gradient of potential, and equipotential surfaces are always perpendicular to field lines.
引力势定义无穷远处为零，因此场内处处为负值；而电势的符号约定则取决于源电荷的正负。场强等于电势的负梯度，等势面始终与场线垂直。
For orbital motion, gravitational attraction provides the centripetal force. Equating GMm/r² = mv²/r gives orbital speed v = √(GM/r), and Kepler’s third law T² ∝ r³ follows directly. Geostationary satellites have a period of 24 hours and orbit in the equatorial plane.
对于轨道运动，万有引力提供向心力。令 GMm/r² = mv²/r 可得轨道速率 v = √(GM/r)，并可直接推导出开普勒第三定律 T² ∝ r³。地球同步卫星的周期为24小时，且位于赤道平面内。
For electric fields, students must analyse parallel plates, point charges and spherical conductors, and calculate the work done in moving charges between different potentials: W = QΔV. The uniform field between parallel plates satisfies E = V/d.
对于电场，学生必须会分析平行板、点电荷和
