📚 Year 12 WJEC Physics: Winter Intensive Revision Plan | Year 12 WJEC 物理：寒假强化复习计划
The winter break offers a golden opportunity for Year 12 students to consolidate their understanding of AS Physics and address any gaps before the pressure of spring exams builds. A focused, well-structured revision plan can transform the holiday period from a passive time into a high-impact learning sprint, especially for the WJEC specification which blends mechanics, electricity, waves, and quantum physics in two broad units. By investing a few hours each day in deliberate practice, you can build the fluency and confidence needed to tackle both multiple-choice questions and structured problems.
寒假为12年级学生提供了一个黄金机会，可以趁春季考试压力来临前巩固对AS物理的理解并弥补薄弱环节。一个专注且结构合理的复习计划能将假期转化为高效率的学习冲刺，尤其对于WJEC考纲而言，该考纲将力学、电学、波动与量子物理融合为两个大单元。每天投入数小时进行有目的的练习，你就能培养起应对选择题与结构化问题所需的熟练度和信心。
1. Know Your WJEC Physics Specification | 了解WJEC物理规范
Before you start revising, familiarise yourself with the exact content of the WJEC Year 12 Physics specification. The AS course is divided into two units: Unit 1 – Motion, Energy and Matter, and Unit 2 – Electricity and Light. Understanding the weighting and style of assessment is key. Each unit accounts for 20% of the full A level, with a 1.5-hour exam containing structured questions, short answer items, and some multiple choice.
在开始复习前，先熟悉WJEC 12年级物理考纲的具体内容。AS课程分为两个单元：第一单元——运动、能量与物质，以及第二单元——电与光。了解各单元的权重和考核形式至关重要。每个单元占整个A Level的20%，考试时长1.5小时，包含结构化问题、简答题和一些选择题。
Unit 1 covers kinematics, dynamics, energy concepts, solids under stress, and using radiation to investigate stars. Unit 2 covers conduction of electricity, resistance, DC circuits, the nature of waves, light (refraction, total internal reflection), and the photon model. Knowing which topics carry the most marks helps you prioritise your revision sessions efficiently.
第一单元涵盖运动学、动力学、能量概念、固体在应力下的行为以及利用辐射探究恒星。第二单元涵盖电流传导、电阻、直流电路、波动本性、光学（折射、全内反射）以及光子模型。了解哪些主题占分更多有助于你合理分配复习时间。
2. Designing Your 4-Week Timetable | 设计四周复习时间表
A realistic timetable breaks your day into focused 60‑minute study blocks. Aim for two to three physics sessions per day, mixing content review, worked examples, and exam-style questions. Below is an example of a weekly schedule that balances the two units while building in rest and reflection time.
一份切实可行的时间表可将一天划分为若干个专注的60分钟学习时段。每天安排两到三个物理学习时段，将内容回顾、例题精练和真题练习结合起来。下表示例平衡了两个单元的复习，同时留出了休息与反思时间。
| Day | Morning (9–10:30) | Afternoon (14–15:30) | Evening (19–20:00) |
|---|---|---|---|
| Mon | Unit 1 content review | Worked examples | Quick-fire MCQs |
| Tue | Unit 2 content review | Required practical write-up | Past paper Q1-4 |
| Wed | Weak area deep dive | Diagram practice | Rest / light reading |
| Thu | Maths skill drill | Longer structured Qs | Flashcard review |
| Fri | Mixed topic test | Mark & analyse | Self-reflection notes |
Stick to the timetable but remain flexible – if a topic demands more time, swap a less urgent session. The goal is steady progress, not rigid perfection.
坚持执行时间表，但保持灵活——如果某个主题需要更多时间，可以替换掉不那么紧急的安排。目标是稳步推进，而非僵化地追求完美。
3. Week 1: Motion, Forces and Vectors | 第一周：运动、力与矢量
Start with the fundamentals. Kinematics and dynamics underpin many other topics. Revisit scalar and vector quantities, and become completely comfortable resolving vectors into components and adding them tip-to-tail. Mastering the SUVAT equations is non-negotiable – they appear in almost every exam paper, often disguised in multi-step contexts.
从基础开始。运动学和动力学是许多其他主题的根基。重温标量与矢量，熟练掌握矢量的分解和三角形法则。掌握SUVAT方程是硬性要求——它们几乎出现在每一份试卷中，常隐藏在多步骤情境中。
Memorise the four equations of uniformly accelerated motion and practise identifying which of the five variables (s, u, v, a, t) are known before blindly plugging numbers in:
记住四个匀加速运动方程，并练习先识别五个变量 (s, u, v, a, t) 中哪些已知，再代入数值：
v = u + a t
s = ½ (u + v) t
v² = u² + 2 a s
s = u t + ½ a t²
Then strengthen your force analysis skills: free-body diagrams, Newton' and using the principle of conservation of momentum in collisions are also key for Unit 1.
然后加强力的分析技能：受力图、牛顿三定律，以及合力与动量变化率的关系 F = Δ(mv)/Δt。计算动量 p = m v 并运用动量守恒原理解决碰撞问题也是第一单元的重点。
4. Week 2: Energy, Materials and Stellar Radiation | 第二周：能量、材料与恒星辐射
rgy ½ m v², and gravitational potential energy m g Δh must become second nature. Understanding the principle of conservation of energy helps you crack problems that mix mechanical and thermal ideas.
这一周合并WJEC考纲第1.4、1.5和1.6节。能量是一个统一概念：功的计算 W = F s cos θ、动能 ½ m v² 和重力势能 m g Δh 必须成为你的本能。理解能量守恒原理能帮助你破解融合了力学与热学思想的题目。
= ΔL/L, then calculate the Young modulus E = stress/strain for a material following Hooke' aphs and distinguish elastic from plastic behaviour. Wires and springs are common contexts – practise finding the gradient of a stress-strain graph in the linear region.
接着，深入研究固体在应力下的行为。定义应力 = F/A 和应变 = ΔL/L，然后计算遵循胡克定律材料的杨氏模量 E = 应力/应变。要能解读力-伸长量图，并区分弹性行为与塑性行为。金属丝与弹簧是常见情境——练习求应力-应变图线性区域的斜率。
Finally, use radiation laws to investigate stars. Stefan's law P = ε σ A T⁴ and Wien' e inverse-square law for intensity to solve problems about distance, brightness and power.
最后，运用辐射定律研究恒星。斯特藩定律 P = ε σ A T⁴ 以及维恩位移定律 λ_max T = 2.9 × 10⁻³ m K 使你能够确定
