Mastering physics starts with mastering the words. This guide is designed to help Year 8 students following the SQA science framework learn, remember, and confidently use essential physics terminology. Instead of rote memorisation, we will use clever hooks, associations, and visual snaps to make every term stick.
学好物理从掌握词汇开始。这份指南专为遵循 SQA 科学框架的 Year 8 学生设计，帮助大家学习、牢记并自信运用物理核心术语。我们不用死记硬背，而是借助巧妙的关联、联想词和图像快照，让每个术语都牢牢扎根。
1. Forces and Motion | 力与运动
Force is a push or a pull. Think of it as any action that can change the way an object moves. A quick memory trick: Force rhymes with 'horse' – imagine a horse pulling a cart.
力是推或拉。可以把它想成任何能改变物体运动状态的作用。速记窍门：力 (Force) 的发音有点像“four狮子”，联想一头狮子在推箱子。
Friction is a force that opposes motion between two surfaces. The word sounds like 'fridge' – imagine sliding a fridge across the floor; it's tough because of friction.
摩擦力是阻碍两个表面之间相对运动的力。这个词听起来像“fridge”（冰箱）——想象推着冰箱在地板上滑，很费力就是因为摩擦力。
Air resistance (or drag) is the friction experienced by objects moving through air. Picture a parachute: the large canopy catches air and slows you down – that is air resistance at work.
空气阻力（或拖拽力）是物体在空气中运动时受到的摩擦力。想象一个降落伞：巨大的伞面兜住空气让你减速——这正是空气阻力在起作用。
| Term | Memory Hook |
| Acceleration | Accelerate = a + celer (fast in Latin) – imagine pressing the 'A' button for a burst of speed. |
| Deceleration | De- means down, so de-celerate = slow down. |
加速度：速度增加的速率；减速度即负加速度，速度减小。把 accelerate 拆成 'a' + 'celer'（拉丁语“快”），就像按下游戏手柄的 A 键冲刺。
2. Energy Types and Transfers | 能量类型与转化
Energy is the ability to do work. It is never created or destroyed, only transferred or converted. Use the phrase 'Energy is like money – you never really lose it, it just changes hands' to remember conservation.
能量是做功的本领。它既不会凭空产生也不会消失，只能转移或转化。用“能量就像钱——不会真的消失，只是换了主人”来记住能量守恒。
Kinetic energy is movement energy. Kin- sounds like 'kinetic' and also like 'kinetic' in cinema – think of a fast-moving film reel. Every moving object has kinetic energy.
动能是运动能量。Kin- 和“cinema”（电影）中的 cine 同源，电影画面在快速移动。任何运动的物体都有动能。
Gravitational potential energy (GPE) t GPE. The higher and heavier, the more GPE. Remember: Gravity + Position = Stored Energy.
重力势能 (GPE) 是因高度而储存的能量。把书放到书架上，它就获得了重力势能。位置越高、物体越重，重力势能越大。记住：重力 (Gravity) + 位置 (Position) = 储存的能量。
- Chemical energy – stored in food, fuel, batteries (think 'chemicals in a battery').
- Thermal energy – heat energy (think 'thermometer').
- Elastic potential energy – stretched or squashed springs and bands (elastic = stretchy).
- Nuclear energy – energy stored inside atoms (nucleus = core).
化学能——储存在食物、燃料、电池中（想想电池里的化学物质）。热（内）能——热能（联想到温度计 thermometer）。弹性势能——被拉伸或压缩的弹簧、橡皮筋（elastic 有弹性的）。核能——储存在原子核中的能量（nucleus 核）。
3. Electricity Basics | 电学基础
Current is the flow of electric charge. Imagine a river current carrying little boats (electrons) along. Symbol: I. Measured in amperes (A). The greater the current, the more charge flows each second.
电流是电荷的流动。想象河流的水流（current）带着小船（电子）前进。符号 I，单位安培 (A)。电流越大，每秒流过的电荷越多。
Voltage sure of water in a pipe; higher voltage = stronger push. Symbol: V, measured in volts (V).
电压（电势差）是驱动电流流动的推力。把电压想象成水管里的水压；电压越高，推力越强。符号 V，单位伏特 (V)。
Resistance is anything that slows the current down. It's like a narrow section in a pipe. Measured in ohms (Ω). The longer or thinner the wire, the greater the resistance.
电阻是任何阻碍电流流动的因素，就像水管中变窄的部分。单位欧姆 (Ω)。导线越长、越细，电阻越大。
A simple mnemonic for Ohm's law (V = I × R) is 'Very Interesting Rat'. It helps recall V (voltage) = I (current) × R (resistance).
欧姆定律 V = I × R 的简单记忆法：“Very Interesting Rat”（非常有趣的耗子），V = I × R。
4. Waves – Light and Sound | 波——光和声
Wavelength is the distance between two matching points on a wave, e.g., crest to crest. Visualise the length of one complete wiggle.
波长是波上两个相邻对应点（如波峰到波峰）之间的距离。想象一次完整摆动的长度。
Frequency per second. High frequency = many waves per second. Unit: hertz (Hz). The term sounds like 'frequent' – how frequently the waves come.
频率是每秒通过某点的波的数目。频率高意味着每秒波数多。单位赫兹 (Hz)。这个词听上去像 'frequent'（频繁），即波来的频繁程度。
Amplitude is the height of a wave from the rest position; it indicates the energy. Louder sound has larger amplitude; brighter light has larger amplitude. The word can be linked to 'ample' – meaning plenty.
振幅是波从平衡位置的最大位移，反映能量大小。声音越响振幅越大；光线越强振幅越大。可以联想 'ample'（充足的），表示振幅大能量足。
Reflection is when a wave bounces off a surface. 'Re-flection' – think of 're' (again) and 'flect' (bend). Mirror reflection is the classic example.
反射指波从表面弹回。'Re-flection'——'re'（再次）加 'flect'（弯曲），就像光从镜面反射。
5. Heat and Temperature | 热与温度
Temperature measures how hot or cold an object is. It does not tell you how much thermal energy it contains. Think of a small cup of boiling water vs a large swimming pool – both can be at 30 °C, but the pool stores far more heat energy.
温度衡量物体的冷热程度，但不能直接说明含有多少热能。一小杯开水和一大游泳池水温可能都是 30 °C，但游泳池储存的热能多得多。
Thermal energy is the total kinetic energy of all particles in an object. The more particles and the faster they move, the greater the thermal energy. Link 'thermal' with 'thermometer'.
热能（内能）是物体内部所有粒子动能的总和。粒子越多、运动越快，热能越大。把 'thermal' 和 'thermometer'（温度计）联系起来记忆。
Conduction = lead; heat is led through the material by vibrating particles knocking into each other.
传导是热量在固体（尤其是金属）中的传递。Con-（一起）+ duct（引导）——热量通过互相碰撞的振动粒子被引导着传递。
Convection is heat transfer in fluids (liquids and gases) where warmer, less dense regions rise. Convection currents are like a circular dance: hot rises, cold sinks. Think of 'convection oven' that uses a fan to circulate hot air.
对流是流体（液体、气体）中的热传递，较热、密度较小的区域上升。对流就像圆圈舞：热升冷降。联想到“对流烤箱”用风扇循环热空气。
6. Magnetism | 磁学
Magnetic field is the area around a magnet where magnetic forces can be felt. Magnetic field lines go from north to south pole outside the magnet. Visualise an invisible 'force bubble' around the magnet.
磁场是磁体周围能感受到磁力的区域。磁感线在磁体外部从北极指向南极。想象磁体周围有一个无形的“力泡泡”。
Poles are the ends of a magnet where the force is strongest. North and south poles: opposites attract, likes repel. Remember: 'Opposites attract' – like people sometimes!
磁极是磁体上磁力最强的端点。北极和南极：异极相吸，同极排斥。记住：异性相吸——就像人与人之间有时也是如此！
Electromagnet lectro- = electricity + magnet. It is the backbone of electric bells and scrapyard cranes.
电磁铁是通过线圈通电产生的暂时磁体，可以开关。Electro-（电）+ magnet（磁体）。它是电铃和废料场起重机的核心部件。
7. Matter and Particles | 物质与粒子模型
Everything is made of tiny particles. The particle model explains the properties of solids, liquids and gases. In solids, particles are tightly packed and vibrate in fixed positions. In liquids, they can slide past each other. In gases, they move quickly in all directions.
万物由微小粒子构成。粒子模型解释了固体、液体和气体的性质。固体中粒子紧密排列，只能在固定位置振动；液体中粒子可以相对滑动；气体中粒子快速向四面八方运动。
Diffusion an is the movement of particles from an area of high concentration to low concentration. It happens in liquids and gases. Think 'diffuse' = spread out. A perfume smell spreading across a room is diffusion.
扩散是粒子从高浓度区域向低浓度区域运动的过程，发生在液体和气体中。想想 'diffuse'（散开）。香水味弥漫整个房间就是扩散。
Pressure in gases is caused by particles colliding with container walls. More particles or faster particles mean higher pressure. Inflate a balloon – the air particles are hitting the inside walls, creating pressure.
气体的压强由粒子撞击容器壁产生。粒子越多或运动越快，压强越高。吹气球时，空气粒子不断撞击气球内壁形成压强。
8. Light and the Electromagnetic Spectrum | 光与电磁波谱
Light to our eyes. It travels in straight lines at a speed of 3 × 10⁸ m/s in a vacuum. Remember: 'Straight as a laser beam.'
光是人眼可见的电磁辐射。光在真空中沿直线传播，速度约为 3×10⁸ 米/秒。记住：“像激光一样直”。
Refraction is the bending of light as it passes from one medium to another (e.g., air to water). The word sounds like 're-fracture' – the light changes direction as if its path is fractured. A pencil in a glass of water looks bent due to refraction.
折射是光从一种介质进入另一种介质（如空气到水）时发生弯曲的现象。词听起来像 're-fracture'（再断裂），光线方向的改变仿佛路径被折。水杯里的铅笔看起来弯折就是因为折射。
Spectrum: white light can be split into seven colours (rainbow) – red, orange, yellow, green, blue, indigo, violet. Use the acronym ROY G BIV to remember the order.
光谱：白光可以分解成七色（彩虹）——红橙黄绿蓝靛紫。用首字母缩写 ROY G BIV（男生名 Roy G. Biv）来记顺序。
9. Energy Resources and Sustainability | 能源与可持续性
Renewable energy comes from sources that won' ike solar, wind, tidal, wave, geothermal and biomass. Renew = again, so renewed by nature.
可再生能源来自不会枯竭的资源，如太阳能、风能、潮汐能、波浪能、地热和生物质。Re-（再）+ new（新），即自然不断更新。
Non-renewable energy oil, natural gas) and nuclear fuels. Once used, they are gone for millions of years. Think 'non-renewable = no second chance'.
不可再生能源包括化石燃料（煤、石油、天然气）和核燃料。一旦使用，数百万年内无法再生。记住“不可再生 = 没有第二次机会”。
Efficiency d to what you put in. It is often shown as a percentage. Useful output ÷ total input × 100%. A high-efficiency device wastes less energy.
效率是衡量有用输出能量与输入能量之比的量，通常写成百分比：有用输出 ÷ 总输入 × 100%。高效率的设备浪费的能量更少。
10. Measurement, Units and Scientific Skills | 测量、单位与科学技能
Key physical quantities have standard international (SI) units. Learning the base units helps decode derived ones.
| Quantity | SI Unit | Symbol |
| Length | metre | m |
| Mass | kilogram | kg |
| Time | second | s |
| Temperature | degree Celsius | °C |
| Force | newton | N |
| Energy | joule | J |
基本物理量都有国际单位制 (SI) 单位。记住基本单位有助于理解衍生单位。长度-米 (m)，质量-千克 (kg)，时间-秒 (s)，温度-摄氏度 (°C)，力-牛顿 (N)，能量-焦耳 (J)。
Precision vs Accuracy he bullseye; precision = hitting the same spot every time, even if it is not the bullseye.
精密度与准确度：精密的结果彼此紧密聚集；准确的结果接近真实值。形象记忆：准确度 = 击中靶心；精密度 = 次次打中同一个点，哪怕不是靶心。
11. Scientific Enquiry Terms | 科学探究术语
Hypothesis is an educated guess that you test with an experiment. It often starts with 'If... then... because...'. Hypo- (under) + thesis (idea) – a preliminary idea.
假设是一个基于知识的猜测，可通过实验检验。常以“如果……那么……因为……”开头。Hypo-（下）+ thesis（观点）——一个初步观点。
Variable: independent variable is the one you change; dependent variable is the one you measure; control variables stay the same. 'I change the Independent, I measure the Dependent' – note the initials: I Do.
变量：自变量是你改变的；因变量是你测量的；控制变量保持不变。“我改变自变量 (Independent)，我测量因变量 (Dependent)”——注意缩写 I 和 D。
Conclusion sums up what you found, referring back to the hypothesis. A strong conclusion also explains results using scientific knowledge.
结论总结你的发现，并回扣假设。有力的结论还要用科学知识解释结果。
12. Quick-Fire Mnemonics and Memory Chains | 闪记口诀与记忆链
Create short rhymes to link terms together. For example, for the order of the electromagnetic spectrum from long to short wavelength: Real Men Inject Viagra Until eXplosive Growth (Radio, Microwaves, Infrared, Visible, Ultraviolet, X-rays, Gamma). Silly, but unforgettable.
编顺口溜能把术语串起来。比如电磁波谱从长波到短波：Red Monkeys In Velvet Underpants X-rayed Grandparents（Radio, Microwave, Infrared, Visible, UV, X-ray, Gamma）。虽滑稽，却难忘。
Use the method of loci: imagine placing key physics terms in different rooms of your house. For instance, Force in the gym, Energy in the kitchen (where food provides chemical energy), Waves in the bathroom (water ripples). Walk through mentally to retrieve them in an exam.
用记忆宫殿法：想象把关键物理术语放在家里的不同房间。例如，力放在健身房，能源放在厨房（食物提供化学能），波放在浴室（水波纹）。在脑海里走过这些房间，考试时就能提取出来。
Draw diagrams: For circuit symbols or wave parts, a quick sketch is often worth a hundred words. The more connections you build, the stronger your recall.
画图：对于电路符号或波的要素，一幅速写往往胜过百字描述。你建立的关联越多，回忆就越牢固。
