The Christmas break is the perfect opportunity to review and strengthen your understanding of Year 7 Physics. This four‑week intensive revision plan breaks down all the key AQA topics into manageable chunks, helping you build confidence and exam skills without feeling overwhelmed.
圣诞假期是回顾和巩固 7 年级物理知识的绝佳时机。这份四周强化复习计划将所有 AQA 关键主题分解成易于管理的部分，帮助你在不感到负担的情况下建立信心并提升考试技巧。
1. Overview of Year 7 AQA Physics Topics | 7 年级 AQA 物理主题概览
Before you start, it’s important to know exactly what you need to cover. Year 7 AQA Physics focuses on Energy, Forces, Electricity, Waves, the Particle Model of Matter, and Space.
开始之前，清楚了解需要复习的内容非常重要。7年级 AQA 物理主要涵盖能量、力、电、波、物质的粒子模型以及太空。
Use the AQA KS3 specification or your school’s topic list to tick off each area as you go. This plan will guide you week by week through the core concepts and common question types.
利用 AQA KS3 大纲或学校提供的主题列表，在复习过程中逐一勾选。本计划将按周引导你掌握核心概念和常见题型。
2. Week 1: Energy and Energy Resources | 第一周：能量与能源
Energy is the ability to do work and it can be stored in different ways, such as kinetic, thermal, chemical, or gravitational potential energy. You need to be able to identify these stores and describe energy transfers.
能量是做功的能力，它可以以不同形式储存，如动能、热能、化学能或重力势能。你需要能识别这些储能库并描述能量转移过程。
For example, when a ball is dropped, energy transfers from the gravitational store to the kinetic store. Always mention the pathway: mechanically, electrically, by heating, or by radiation.
例如，当球落下时，能量从重力势能库转移到动能库。始终要说明转移途径：机械做功、电做功、加热或辐射。
In a Sankey diagram, the total energy input equals the sum of useful output and wasted energy. Remember that wasted energy is often dissipated as heat to the surroundings.
在桑基图中，总输入能量等于有用输出能量与浪费能量之和。记住，浪费的能量通常以热的形式散失到周围环境中。
Your daily task this week: draw five energy transfer diagrams for everyday situations, like a hairdryer or a moving bicycle.
本周每日任务：为日常情景画出五幅能量转移图，比如吹风机或行驶中的自行车。
3. Week 2: Forces and Motion | 第二周：力与运动
A force is a push or a pull that can change the shape, speed, or direction of an object. Forces are measured in newtons (N) and often act in pairs on different objects.
力是推或拉，可以改变物体的形状、速度或方向。力以牛顿 (N) 为单位测量，通常成对作用在不同的物体上。
Balanced forces produce no change in motion, while unbalanced forces cause acceleration or deceleration. Friction and air resistance oppose motion and often turn kinetic energy into thermal energy.
平衡力不会改变运动状态，而非平衡力则导致加速或减速。摩擦力和空气阻力阻碍运动，常常将动能转化为热能。
Speed can be calculated using:
speed (m/s) = distance (m) ÷ time (s)
速度可以用以下公式计算：
速度 (m/s) = 距离 (m) ÷ 时间 (s)
mass. Weight (N) = mass (kg) × gravitational field strength (N/kg). On Earth, g ≈ 10 N/kg.
地球引力使所有物体具有重量，重量不同于质量。重量 (N) = 质量 (kg) × 引力场强度 (N/kg)。在地球上，g ≈ 10 N/kg。
Practise plotting distance–time graphs: a straight line means constant speed, and a horizontal line means the object is stationary.
练习绘制距离 - 时间图：直线表示匀速运动，水平线表示物体静止。
4. Week 3: Electricity and Circuits | 第三周：电与电路
Electric current is the flow of electric charge, measured in amperes (A). For a current to flow, you need a complete circuit with a power source, such as a cell or battery.
电流是电荷的流动，以安培 (A) 为单位测量。要使电流流动，你需要一个包含电源（如电池）的完整电路。
Voltage (potential difference) is the push that drives the current around, measured in volts (V). Resistance, measured in ohms (Ω), opposes the flow. The relationship is:
resistance (Ω) = voltage (V) ÷ current (A)
电压（电位差）是驱动电流的推动力，单位为伏特 (V)。电阻以欧姆 (Ω) 为单位，阻碍电流流动。它们的关系是：
电阻 (Ω) = 电压 (V) ÷ 电流 (A)
In a series circuit, the current is the same everywhere, and the total resistance increases as more components are added. In a parallel circuit, the current splits, but the voltage across each branch is the same.
在串联电路中，各处电流相同，且随着更多元件的加入，总电阻增加。在并联电路中，电流分流，但各支路两端的电压相同。
Draw and label circuit symbols correctly. Build simple circuits online using a simulator if you don’t have practical equipment at home.
正确绘制并标注电路符号。如果家里没有实验器材，可以在线使用模拟器搭建简单电路。
5. Week 4: Waves – Sound and Light | 第四周：波——声音与光
Waves transfer energy from one place to another without transferring matter. Sound waves are longitudinal and require a medium, while light waves are transverse and can travel through a vacuum.
波将能量从一个地方传递到另一个地方，而不传递物质。声波是纵波，需要介质传播；光波是横波，可以在真空中传播。
The speed of sound in air is about 330 m/s. Light travels much faster, at about 300 000 000 m/s. Because light is so fast, we see lightning before we hear thunder.
声音在空气中的速度约为 330 m/s。光速快得多，约为 300 000 000 m/s。因为光速极快，我们总是先看见闪电，后听到雷声。
Reflection occurs when waves bounce off a surface. The law of reflection states that the angle of incidence equals the angle of reflection. Use a ray box diagram to practise.
反射发生在波从表面弹回时。反射定律指出入射角等于反射角。使用光线盒图来练习。
Sound can be reflected as echoes, and its pitch depends on frequency, while loudness depends on amplitude. The ear converts vibrations into electrical signals for the brain.
声音可以反射形成回声，其音调取决于频率，而响度取决于振幅。耳朵将振动转化为电信号传给大脑。
6. The Particle Model of Matter | 物质的粒子模型
All substances are made of tiny particles that are constantly moving. The arrangement and energy of these particles determine whether a substance is a solid, liquid, or gas.
所有物质都由不断运动的微小粒子组成。这些粒子的排列方式和能量决定了物质是固体、液体还是气体。
In solids, particles are closely packed in a regular pattern and vibrate in fixed positions. In liquids, they are close but can slide past each other. In gases, particles are far apart and move rapidly.
固体中，粒子紧密排列成规则形状，只能在固定位置振动。液体中，粒子紧密但能相互滑过。气体中，粒子相距很远并快速运动。
Diffusion is the spreading of particles from an area of high concentration to low concentration. It happens faster at higher temperatures because particles have more kinetic energy.
扩散是粒子从高浓度区域向低浓度区域扩散的过程。温度越高扩散越快，因为粒子的动能更大。
Gas pressure is caused by particles colliding with the walls of their container. Increasing the temperature or decreasing the volume increases the pressure.
气体压强由粒子撞击容器壁造成。升高温度或减小体积都会增大压强。
7. Space Physics | 太空物理
Our Solar System consists of the Sun, eight planets, dwarf planets, moons, asteroids, and comets. The Sun is a star that produces light and heat through nuclear fusion.
我们的太阳系由太阳、八大行星、矮行星、卫星、小行星和彗星组成。太阳是一颗通过核聚变产生光和热的恒星。
Day and night are caused by Earth’s rotation on its axis, which takes 24 hours. The seasons result from Earth’s tilted axis as it orbits the Sun over one year.
昼夜由地球绕地轴自转引起，自转周期为 24 小时。季节则是地球绕太阳公转时由于地轴倾斜而产生的，公转周期为一年。
The Moon orbits Earth roughly every 28 days, showing different phases due to the changing amount of illuminated surface we see. A solar eclipse happens when the Moon passes between Earth and the Sun.
月球大约每 28 天绕地球一周，因我们看到的被照亮面大小变化而呈现不同月相。当月球运行到地球与太阳之间时，就会发生日食。
Massive objects exert gravitational attraction. The force of gravity keeps planets in orbit and holds us on the ground. On the Moon, gravity is weaker, so your weight would be less.
有质量的物体会产生引力。引力使行星保持在轨道上运行，也将我们留在地面上。在月球上，引力较弱，因此你的重量会更小。
8. Practical Investigation Skills | 实验探究技能
AQA Physics includes Working Scientifically skills, so revision must cover planning experiments, identifying variables, and analysing data. The independent variable is the one you change, and the dependent variable is the one you measure.
AQA 物理包含“科学探究”技能，因此复习必须涵盖实验设计、识别变量和分析数据。自变量是你改变的变量，因变量是你测量的变量。
Control variables must be kept the same to ensure a fair test. When writing a method, use clear, numbered steps and refer to specific equipment, such as a stopwatch or ammeter.
控制变量必须保持相同以确保公平测试。编写实验步骤时，使用清晰的编号步骤并指出具体器材，如秒表或安培表。
Record results in tables with units in the header row. Plot line graphs with labelled axes and a suitable scale. Identify anomalies in data – these are points that don’t fit the pattern.
将结果记录在表格中，表头行注明单位。绘制线图时标注轴并选择合适的刻度。识别数据中的异常点——即不符合整体趋势的点。
9. Common Mistakes and How to Avoid Them | 常见错误及避免方法
Many students confuse mass and weight. Mass is measured in kilograms and stays the same everywhere; weight is measured in newtons and depends on gravity. Always check your units.
许多学生混淆质量和重量。质量以千克为单位，处处相同；重量以牛顿为单位，取决于引力大小。务必检查你的单位。
When calculating speed, make sure distance is in metres and time is in seconds. If a question gives units in km or minutes, convert them first.
计算速度时，确保距离用米，时间用秒。如果题目给出的单位是千米或分钟，一定要先换算。
In circuits, do not think current is “used up” by components. Current remains the same around a series loop. Use the analogy of water flow to help you remember.
在电路中，不要以为电流会被元件“用完”。串联回路中的电流处处相等。可以用水流作类比来帮助记忆。
With energy, avoid saying energy is “lost”. Energy is always conserved – it is just transferred to less useful stores, like heat. Use the term “dissipated” in your answers.
在能量方面，不要说能量“消失”了。能量总是守恒的——它只是转移到不太有用的储能库，如热。在答案中使用“散失”一词。
10. Sample Questions and Model Answers | 例题与标准答案
Try this question: “A student walks 150 m to the park in 50 seconds. Calculate her average speed.” Model answer: speed = 150 ÷ 50 = 3 m/s.
试做这道题：“一名学生用 50 秒走了 150 米到公园。计算她的平均速度。” 标准答案：速度 = 150 ÷ 50 = 3 m/s。
Another example: “Describe the energy transfers when a battery‑powered torch is switched on.” Answer: Energy transfers electrically from the chemical store of the battery to the thermal and light stores of the bulb, with some energy dissipated as heat to the surroundings.
另一例子：“描述电池驱动的手电筒打开时发生的能量转移。” 答案：能量通过电力途径从电池的化学能库转移到灯泡的热能库和光能库，同时部分能量以热的形式散失到周围环境中。
Exam command words like “describe”, “explain”, and “calculate” require different approaches. “Describe” needs a step‑by‑step account, while “explain” must include scientific reasons.
考试中“描述”、“解释”和“计算”等指令词要求不同的作答方式。“描述”需要逐步叙述，而“解释”必须包含科学理由。
Spend 20 minutes each day answering one or two questions from a KS3 Physics workbook. Check your answers using the mark scheme and correct any misconceptions.
每天花 20 分钟回答 KS3 物理练习册中的一两道题。对照评分方案检查答案，纠正任何错误观念。
11. Revision Techniques That Work | 有效的复习方法
Active revision is far better than simply reading notes. Write flash cards with a question on one side and the answer on the other, then test yourself without looking.
主动复习远胜于单纯阅读笔记。制作抽认卡，一面写问题，另一面写答案，然后不看答案进行自测。
Use mind maps to connect ideas: start with “Energy” in the centre and branch out to stores, transfers, efficiency, and power. Colour‑coding helps memory.
使用思维导图连接各个概念：以“能量”为中心，分支出储能库、转移、效率和功率等。用颜色编码有助于记忆。
Teach a topic to a family member or even your pet. Explaining out loud forces you to organise your thoughts and reveals any gaps in your understanding.
向家人甚至宠物讲解一个主题。大声解释能迫使你理清思路，并暴露出理解上的漏洞。
Build a daily routine: 25 minutes of focused revision followed by a 5‑minute break. This Pomodoro method maintains concentration over longer periods.
建立日常习惯：专注复习 25 分钟，然后休息 5 分钟。这种番茄工作法能让你在较长时间内保持专注。
12. Self‑Assessment and Staying Motivated | 自我评估与保持动力
At the end of each week, complete a short self‑assessment quiz. Rate your confidence for each subtopic on a scale of 1‑3 and highlight areas you still find difficult.
每周结束时，完成一个简短的自我评估小测验。用 1-3 分评估你对每个子主题的信心，并标出仍有困难的领域。
Set small rewards for reaching goals, such as a favourite snack or some free time. A positive mindset makes a huge difference to your progress.
为目标达成设置小奖励，比如喜欢的零食或一些自由时间。积极的心态会对你的进步产生巨大影响。
Don’t compare yourself to others; focus on your own improvement. Celebrate the fact that you are now able to answer questions that once seemed impossible.
不要与别人比较，专注于自己的提高。庆祝你现在能够回答那些曾经看似不可能的问题。
Remember that Year 7 Physics provides the foundation for future topics in Years 8 and beyond. Master the basics now, and you will find later studies much smoother.
请记住，7 年级物理为 8 年级及以后的课程奠定了基石。现在就掌握基础知识，你会发现未来的学习会顺畅得多。
