This guide will walk you through the most effective strategies for tackling AQA Physics questions, explain how marks are awarded, and help you avoid common pitfalls that cost grades every single year.
Year 10 AQA 物理考试旨在考查的不仅是你掌握了哪些知识，更重要的是你在限时条件下应用知识的能力、分析陌生情境的能力以及清晰地表达科学观点的能力。掌握答题技巧与复习知识内容同等重要，因为即使是学科知识扎实的学生，如果看不懂题目真正想问什么，或者没有按照评分标准来组织答案，也一样会丢分。本指南将带你逐一掌握应对 AQA 物理考题的最有效策略，讲解分数是如何给出的，并帮助你避开每年都让大批学生白白丢分的常见陷阱。
1. Understanding Command Words | 理解指令词
State: This is the simplest command and expects a direct, factual answer – often just a word, a phrase or a numerical value. There is no need to explain or justify your response. For example, “State the unit of work done.” could be answered with “joule” or “J”. A full sentence is safe but not always required; however, reading the question carefully will tell you if extra detail is needed.
陈述 (State)：这是最简单的指令，期望一个直接的事实性答案——通常只需一个词、一个短语或一个数值。你不需要解释或证明你的回答。例如，“陈述功的单位”可以回答“焦耳”或“J”。写出完整的句子是稳妥的，但并非总是必需；不过仔细读题会让你知道是否需要额外细节。
Describe: Here you need to give a detailed account of what happens, what is observed or what a graph shows – but you do not need to explain why it happens. Think of the steps or features, and link them in a logical order. For instance, “Describe how the current varies as the potential difference across a filament lamp increases.” requires you to say that the current initially rises steadily, then the rate of increase slows, without explaining the cause in this part.
描述 (Describe)：此处你需要详细叙述发生了什么、观察到了什么或者曲线显示了什么——但不必解释为什么发生。想清楚其中的步骤或特征，然后按逻辑顺序串联起来。例如，“描述随着灯丝灯泡两端电势差增大，电流如何变化”要求你说明电流起初稳定上升，随后上升速率变慢，而无需在这一问中解释原因。
Explain: This command is often worth more marks and always requires you to give reasons, linking cause and effect using scientific principles. You must use words like ‘because’, ‘therefore’ or ‘so’ to show the connection. An explanation might involve describing an underlying mechanism (e.g. resistance increases because ions vibrate more and this causes more collisions with electrons). Every physics ‘explain’ question expects a chain of reasoning that leads clearly from the given situation to the outcome.
解释 (Explain)：这一指令通常分值更高，并且总是要求你给出理由，运用科学原理将因果关系串联起来。你必须使用“因为”“因此”“所以”这类词来展示关联。一个解释题的回答可能涉及描述底层机制（例如，电阻增大是因为离子振动更剧烈，这导致电子碰撞更多）。每一道物理“解释”题都期望你给出一条清晰的推理链，从给定情境通向最终结果。
Calculate: You must perform a mathematical operation and present the answer with the correct unit. The mark scheme will often award marks for showing the formula, substituting numbers and giving the final answer to an appropriate number of significant figures. Even if you get the final number wrong, showing your working can earn you method marks.
计算 (Calculate)：你必须进行数学运算，并给出带有正确单位的答案。评分标准通常会给写出公式、代入数据和给出最终答案（保持合适的有效数字）分别奖励分数。即便最后的数字算错了，只要写出了计算过程，就有可能拿到方法分。
Compare: This means you need to identify both similarities and differences. Simply stating how two things differ is not enough – you must point out what is the same as well. Using comparative language such as “both … whereas …” or “similarly … but …” will help you structure a response that hits all the marking points.
比较 (Compare)：这意味着你需要找出相似点和不同点。仅仅说出两者有何不同是不够的——你必须同时指出相同之处是什么。使用比较句式，如“两者都……而……”或“类似地……但是……”将有助于你组织出一个能覆盖所有踩分点的答案。
Evaluate: This is a higher-order skill. You are expected to make a judgement, weighing up evidence and discussing both advantages and disadvantages before reaching a conclusion. In physics, this might appear in questions about experimental methods or the use of a particular energy resource. Simply listing pros and cons is not enough; you must state clearly which side is more significant and why.
评价 (Evaluate)：这是一种高阶技能。你需要做出判断，权衡证据，讨论优点与缺点，最终得出结论。在物理中，这类指令可能出现在关于实验方法或某种能源使用的问题中。只罗列利弊是不够的；你必须明确指出哪一方更为重要并说明理由。
2. Decoding the AQA Mark Scheme | 解读 AQA 评分标准
Every AQA Physics question is written with a specific mark scheme in mind, and understanding how examiners allocate marks will directly improve your answers. In general, marks are awarded for achieving ‘marking points’ – these are the distinct pieces of correct physics that the examiner is looking for. A 3-mark ‘explain’ question, for instance, usually expects three separate points of reasoning. If you write a long paragraph that only contains one substantive idea, you will only receive one mark.
每一道 AQA 物理题都有一个明确的评分标准作为依据，理解考官如何分配分数能直接提高你的作答质量。通常来说，分数是给予“踩分点”的——也就是考官期待的那些独立的正确物理陈述。例如，一道 3 分的“解释”题通常要求三段独立的推理。如果你写了一大段话却只包含一个实质观点，就只能拿到 1 分。
You will often see the abbreviation ‘allow’ in published mark schemes. This indicates alternative acceptable answers. For example, if the correct response is “potential difference”, the scheme might say “allow voltage”. This tells you that both terms are equally valid, but it also highlights that official terminology is always preferred. Using precise scientific vocabulary never hurts and removes any ambiguity.
你在已公布的评分标准中会经常看到“allow（允许）”这个缩写，它表示其他可接受的答案。例如，正确答案是“potential difference（电势差）”，评分标准可能会说“allow voltage（允许答电压）”。这告诉你两个术语同样有效，但也突出了官方术语总是优先的。使用精确的科学词汇永远不坏事，而且能消除任何歧义。
Another critical feature is the use of ‘or’ in mark schemes. When two marking points are separated by ‘or’, it means you only need to give one of them – not both. However, if they are bullet points without ‘or’, you need to mention each one to gain full marks. Reading past papers and their corresponding mark schemes is the best way to internalise this logic.
另一个关键特征是评分标准中“or（或）”的使用。当两个踩分点用“或”分隔时，意味着你只需给出其中一个——不必两者都写。但如果它们是以项目符号列出且不含“或”，你就需要提到每一点才能拿到满分。通过研读历年真题及对应评分标准是内化这套逻辑的最佳途径。
Marks are also allocated according to Assessment Objectives: AO1 is demonstrating knowledge, AO2 applying that knowledge and AO3 analysing information and evaluating. A typical paper balances these, so you cannot rely only on memorisation; you must practise applying concepts to new data and drawing conclusions from experimental results.
分数还会根据评估目标来分配：AO1 是展示知识，AO2 是应用知识，AO3 是分析信息和作出评价。一份典型的试卷是平衡这三者的，因此你不能只靠记忆；你必须练习把概念应用到新的数据上，并根据实验结果得出结论。
3. Mastering Calculation Questions | 掌握计算题
Calculation questions in AQA Physics reward a clear, step-by-step approach. The examiner wants to see your thinking, so never skip straight to the answer. Even a straightforward calculation like finding the speed from distance and time can earn three marks: one for stating the correct equation, one for correct substitution and one for the right answer with the right unit. If you make a numerical slip but your method is visible, marks can still be awarded.
AQA 物理的计算题奖励清晰、一步一步的解题过程。考官希望看到你的思路，所以永远不要直接跳到最后答案。即使是一个简单的计算，比如用距离和时间求速度，也可能值 3 分：1 分给写出正确公式，1 分给正确代入，1 分给带正确单位的最终答案。即使你算错了数值，只要方法清晰可见，仍有可能得分。
As an example, consider: “A car travels 150 m in 5.0 s. Calculate its speed.”
speed = distance / time
Your working should be presented as:
speed = 150 / 5.0 = 30 m/s
Notice that the unit is essential: writing ’30’ without the unit would lose a mark. If the question supplies data to two or three significant figures, you should normally give your answer to the same number of significant figures – here 5.0 has two significant figures, so 30 m/s is correct.
举个例子：“一辆汽车在 5.0 秒内行驶了 150 米。计算它的速度。”解题过程应该呈现为：
速度 = 距离 / 时间 = 150 / 5.0 = 30 m/s
注意单位必不可少：写“30”而不写单位会丢分。如果题目给出的数据是两位或三位有效数字，你通常也应该将答案保留为同样位数的有效数字——这里 5.0 是两位有效数字，所以 30 m/s 是正确的。
When rearranging equations, do it step by step. For example, to find the force needed to produce a pressure of 50 Pa over an area of 0.20 m²:
pressure = force / area → force = pressure × area
Then substitute: force = 50 × 0.20 = 10 N. Showing this reasoning protects you against errors and makes it easy for the examiner to award method marks.
在变形公式时，一步一步来做。例如，要求产生 50 Pa 压强、作用面积为 0.20 m² 所需的力：
压强 = 力 / 面积 → 力 = 压强 × 面积
然后代入：力 = 50 × 0.20 = 10 N。展示这一推理过程能防止出错，也方便考官给方法分。
Finally, be careful with standard form and unit conversions. If you are working with mA, cm² or kJ, convert everything to A, m² and J before you calculate, unless the formula specifically uses those units. Write the conversion clearly on your page as part of your working.
最后，小心标准形式和单位换算。如果你要用到毫安、平方厘米或千焦，除非公式特别规定，否则在计算之前先把所有单位换算成安培、平方米和焦耳。把换算过程清楚写在卷面上，作为解题步骤的一部分。
4. Tackling ‘Explain’ and ‘Describe’ Questions | 应对“解释”和“描述”题
The difference between describe and explain is one of the most common sources of lost marks. Describe questions require a factual, sequential account of what is happening. For a distance-time graph showing constant speed, a full-mark description might be: “The line is straight and sloping upwards, meaning the object moves equal distances in equal time intervals.” Do not add “because the resultant force is zero” – that belongs in an explanation.
描述和解释的区别是最常见的丢分点之一。描述题要求对正在发生的事情做出事实性、顺序性的叙述。对于一张显示匀速运动的距离–时间图，一个满分的描述可以是：“线是笔直向上倾斜的，表示物体在相等时间间隔内移动了相等的距离。”不要加上“因为合力为零”——那属于解释题的内容。
Explain questions require a causal chain. For the same graph, if asked to explain why the line is straight for a car moving at steady speed, you might write: “The car’s engine provides a driving force that balances the resistive forces, so the resultant force is zero. According to Newton’s first law, zero resultant force means the velocity is constant, producing a straight distance-time graph.” Each clause adds a new piece of reasoning, which matches the marking points.
解释题要求一条因果链。同样是这张图，如果要求解释为什么匀速运动的汽车对应的图线是直的，你可以写：“汽车发动机提供的驱动力与阻力平衡，因此合力为零。根据牛顿第一定律，合力为零意味着速度恒定，从而产生一条直线的距离–时间图。”每一个分句都增加了一段新的推理，正好匹配踩分点。
Another type of question asks you to describe a trend from a graph or table, then explain it. Always separate the two parts clearly. Write the description first (“as potential difference increases, current increases”) and then start a new sentence or paragraph with “This is because…” to launch your explanation. This structure prevents the examiner from thinking you have confused the two skills.
还有一种题型要求你先描述图表或表格中的趋势，然后进行解释。一定要把这两部分清晰分开。先写描述（“随着电势差增大，电流也增大”），然后新起一句或一段，用“这是因为……”来展开你的解释。这样的结构能防止考官认为你把两种技能搞混了。
5. Using Scientific Vocabulary | 使用科学词汇
Examiners are trained to recognise precise scientific language, and they can only award marks if you express ideas in a physically correct way. Saying “the energy goes away” is vague and unlikely to gain credit; writing “energy is transferred to the thermal store of the surroundings” is specific and directly matches the mark scheme. Every AQA topic has a set of key terms – learn them actively, not just by reading but by writing definitions from memory.
考官训练有素，能识别精确的科学语言，而且只有当你用物理上正确的方式表达观点时，他们才能给分。说“能量跑掉了”是含混的，很难得到分数；而写“能量被传递到周围环境的热储库中”则明确具体，直接符合评分标准。每个 AQA 课题都有一套关键术语——你要主动去学习它们，不是只靠阅读，而是凭记忆写出定义。
Commonly confused terms include ‘speed’ and ‘velocity’ (velocity has direction), ‘mass’ and ‘weight’ (weight is a force measured in newtons, mass is measured in kilograms), and ‘heat’ and ‘temperature’
