📚 AQA AS Physics 9630 PH02 Specimen Paper 2016: Key Topics and Revision Guide | AQA 国际 AS 物理 9630 PH02 样卷 2016：核心考点与复习指南

The AQA International AS Physics 9630 PH02 specimen paper is a vital resource for students preparing for Unit 2. It tests electricity, waves, and particles, with an emphasis on applying principles to unfamiliar circuits and wave contexts. This guide breaks down the main question types, common pitfalls, and the exam techniques that markers expect.

AQA 国际 AS 物理 9630 PH02 样卷是备考第二单元的重要材料。试卷考查电学、波以及粒子等主题，强调在陌生电路与波动情境中运用物理原理。本文拆解主要题型、常见失分点以及考官期望的答题技巧。

1. Paper Structure and Assessment Objectives | 试卷结构与评估目标

The PH02 specimen paper contains a mix of multiple-choice, short-answer and longer structured questions covering electricity, waves and particles.

PH02 样卷包含选择题、简答题和较长的结构化题目，涵盖电学、波动与粒子等内容。

Assessment Objective AO1 tests recall of definitions and laws, AO2 requires applying these ideas to new contexts, and AO3 focuses on analysis, interpretation and evaluation of data.

评估目标 AO1 考查定义和定律的回忆，AO2 要求将知识应用到新情境中，AO3 则侧重数据分析和评价。

The specimen mark scheme rewards precise scientific language, so vague phrasing such as ‘more current’ without a reason will not earn full marks.

样卷评分方案青睐精确的科学表述，因此类似“电流更大”而无因果解释的模糊说法不会得满分。

2. Command Words and Marking Style | 指令词与评分方式

Common command words in PH02 include ‘state’, ‘define’, ‘calculate’, ‘show that’, ‘explain’, and ‘suggest’. Each requires a different depth of response.

PH02 中常见的指令词包括“陈述”“定义”“计算”“证明”“解释”和“建议”。不同指令词要求不同的作答深度。

‘Show that’ questions expect you to use a numerical answer or given formula and produce clear intermediate steps, not just a final line.

“证明”题要求使用数值或已知公式，写出清晰的中间步骤，而不仅仅是最后一行。

In ‘explain’ questions, always link physical principles to the specific situation; for example, a temperature rise increases resistance because lattice vibrations scatter electrons more.

在“解释”题中，始终要把物理原理与具体情境联系起来；例如温度升高使电阻增大，是因为晶格振动更剧烈，散射电子更明显。

3. Charge, Current and Potential Difference | 电荷、电流与电势差

Current is the rate of flow of charge, defined by I = Q ÷ t, where Q is the charge in coulombs and t is time in seconds.

电流是电荷流动的速率，定义为 I = Q ÷ t，其中 Q 是以库仑为单位的电荷，t 是以秒为单位的时间。

I = Q / t

The potential
