Mastering the essential terminology is half the battle in Edexcel AS Physics. This guide breaks down key terms by topic, offering memory hooks, word origins, and conceptual contrasts to help you recall definitions accurately under exam pressure. Each entry links a term to its physical meaning, so you never confuse ‘precision’ with ‘accuracy’ or ‘elastic limit’ with ‘limit of proportionality’ again.

掌握核心术语是攻克 Edexcel AS 物理的关键一步。本指南按主题梳理关键术语，提供记忆挂钩、词源解析和概念对比，帮助你在考试压力下准确回忆定义。每个术语都与其物理含义紧密相连，让你再也不会混淆“精密度”与“准确度”或“弹性极限”与“比例极限”。

1. Mechanics: Motion & Forces | 力学：运动与力

In mechanics, many terms are vector quantities, which means direction matters. A displacement is not the same as distance — the former is a vector from a reference point, while the latter is the total ground covered. Think: ‘displacement’ contains ‘place’, suggesting a specific location change.

力学中许多术语是矢量，意味着方向很重要。位移与路程不同——前者是从参考点出发的矢量，后者是经过的总路径长度。记法：“displacement”含有“place”，指向特定的位置变化。

Velocity: rate of change of displacement. It is a vector; speed is scalar. Imagine the ‘v’ in velocity as an arrowhead pointing in the direction of motion.
速度 (Velocity)：位移的变化率。它是矢量；速率是标量。把 velocity 中的 ‘v’ 想象成一个箭头，指向运动方向。
Acceleration: rate of change of velocity. Can be negative (deceleration) but label it carefully. Derived from Latin ‘accelerare’ — to hasten.
加速度 (Acceleration)：速度的变化率。可为负（减速），但需谨慎标注。词源：拉丁语“accelerare”——加速。
Resultant force: the single force that has the same effect as all forces acting on a body. Think ‘result’ — the net outcome of all pushes and pulls.
合力 (Resultant force)：与物体所受所有力作用效果相同的单一力。联想“result”（结果）——所有推拉的净效应。
Moment: force × perpendicular distance from the pivot. A moment turns things. Think of a ‘moment in time’ that rotates your day.
力矩 (Moment)：力 × 到支点的垂直距离。力矩使物体转动。想象一个“moment in time”扭转了你的一天。

Newton’s three laws can be remembered by the acronym IMA: Inertia (First), Momentum (Second, F=dp/dt), Action-reaction (Third). Recite: “I Move Actively.”

牛顿三定律可用首字母 IMA 记忆：惯性（第一定律），动量（第二定律，F=dp/dt），作用与反作用（第三定律）。背诵口诀：“IMA 记住 I Move Actively”。

2. Mechanics: Energy & Power | 力学：能量与功率

Work done is energy transferred, and it only happens when a force causes displacement in its direction. If you carry a box horizontally, no mechanical work is done on the box because the force is vertical while displacement is horizontal. The word ‘work’ in physics always requires motion in the direction of the force.

做功是能量的转移，只有当力在其方向上引起位移时才发生。如果你水平搬运箱子，对箱子没有做机械功，因为力是竖直的而位移是水平的。物理学中“功”一词总要求沿力方向的运动。

Kinetic energy (Eₖ = ½mv²): energy due to motion. ‘Kinetic’ comes from Greek ‘kinesis’ meaning movement — think of kinetic sand flowing.
动能 (Eₖ = ½mv²)：因运动而具有的能量。“Kinetic”源自希腊语“kinesis”，意为运动——联想流动的动能沙。
Gravitational potential energy (ΔEₚ = mgΔh): energy due to position in a gravitational field. ‘Potential’ means stored possibility — it has the potential to fall.
重力势能 (ΔEₚ = mgΔh)：因在引力场中的位置而具有的能量。“Potential”指储存的可能性——它有下落的潜力。
Power: rate of doing work. Unit watt (J/s). A powerful engine does work fast, not necessarily more work. Think of a sprinter vs marathoner: same work, different power.
功率 (Power)：做功的速率。单位瓦特（J/s）。大功率发动机做功快，而不一定做功多。想象短跑运动员与马拉松选手：做功相同，功率不同。
Efficiency: useful output energy / total input energy. Always between 0 and 1 or expressed as a percentage. NO machine is 100% efficient.
效率 (Efficiency)：有用输出能量 / 总输入能量。总在 0 到 1 之间或表示为百分比。没有机器是 100% 有效的。

Principle of conservation of energy: energy cannot be created or destroyed, only transferred or transformed. Remember it as the unbreakable rule of physics accounting.

能量守恒定律：能量不能创造也不能消灭，只能转移或转化。把它当作物理学记账的铁律来记忆。

3. Materials: Stress, Strain & Young Modulus | 材料：应力、应变与杨氏模量

These terms are often confused because they sound similar in everyday language. In physics, stress is the cause, strain is the effect. Stress (σ = F/A) is like pulling a spring — force per area. Strain (ε = ΔL/L) is the fractional extension, a dimensionless ratio. Think of ‘stress’ making you stretch; the amount you stretch is the ‘strain’.

这些术语常因日常用语相似而混淆。物理学中，应力是因，应变是果。应力 (σ = F/A) 就像拉弹簧——单位面积的力。应变 (ε = ΔL/L) 是延伸的比例，无量纲比值。想象“stress”让你拉伸；你伸长的量就是“strain”。

Hooke’s Law: extension is proportional to force, up to the limit of proportionality. F = kΔL. Think of a hook holding a spring — within limits, it stretches linearly.
胡克定律 (Hooke’s Law)：在比例极限内，伸长量与力成正比。F = kΔL。联想钩子 (hook) 拉住弹簧——在限度内线性伸长。
Limit of proportionality: the point beyond which force and extension are no longer proportional. The graph stops being a straight line.
比例极限 (Limit of proportionality)：力与伸长不再成正比的点。图像不再为直线。
Elastic limit: the maximum stress that can be applied without permanent deformation. After this, the material stays stretched. ‘Elastic’ means it can snap back; beyond this limit, it doesn’t.
弹性极限 (Elastic limit)：不产生永久变形的最大应力。超过此点，材料保留伸长。“Elastic”意味着可弹回；超过极限则不能。
Young modulus (E = σ/ε): measure of stiffness. A steep stress-strain line means high E. Named after Thomas Young, but just remember “Why Young? Because it’s stiff and youthful!”
杨氏模量 (E = σ/ε)：刚度的量度。应力-应变线陡峭意味着 E 大。以 Thomas Young 命名，记忆口诀：“Young 代表年轻刚硬”。
Ductile vs Brittle: Ductile (like copper) can be drawn into wires and shows large plastic deformation; brittle (like glass) snaps with little strain. ‘Ductile’ contains ‘duct’ — like a tube you can pull.
延性 vs 脆性：延性材料（如铜）可拉成丝且有大塑性变形；脆性材料（如玻璃）在小应变下断裂。“Ductile”含“duct”（管道）——可被拉长。

4. Waves: General Properties | 波：基本性质

Waves transfer energy without transferring matter. The key distinction is between transverse and longitudinal waves. In transverse waves, oscillations are perpendicular to energy transfer (light, water surface). In longitudinal waves, oscillations are parallel (sound, P-waves). To remember: “Transverse has the ‘T’ crossing perpendicular; Longitudinal has ‘long’ along direction.”

波传递能量而不传递物质。关键区别是横波与纵波。横波中，振动垂直于能量传递方向（光、水面波）。纵波中，振动平行于能量传递方向（声波、P 波）。记忆口诀：“Transverse 中的 ‘T’ 横交垂直；Longitudinal 中的 ‘long’ 沿方向”。

Amplitude (A): maximum displacement from equilibrium. A bigger amplitude means more energy. Symbol A — think ‘Altitude’ of the wave.
振幅 (Amplitude)：离开平衡位置的最大位移。振幅越大，能量越多。符号 A——联想波浪的“海拔”。
Wavelength (λ): distance between two consecutive points in phase, e.g., crest to crest. Lambda (λ) looks like a wave.
波长 (λ)：两个相邻同相位点之间的距离，如波峰到波峰。λ 形状像波。
Frequency (f): number of complete oscillations per second. Unit hertz (Hz). Think of how ‘frequent’ the waves arrive.
频率 (f)：每秒完整振动的次数。单位赫兹 (Hz)。想象波到来的“频繁”程度。
Period (T): time for one full cycle. T = 1/f. The ‘period’ is the full duration of one wave story.
周期 (T)：一个完整循环的时间。T = 1/f。“Period”是一个波故事的完整持续时间。
Phase difference: how much one wave leads or lags another, measured in degrees or radians. In phase = 0°, antiphase = 180°. Think of two runners on a circular track.
相位差 (Phase difference)：一个波超前或滞后另一个波的程度，以度或弧度度量。同相 = 0°，反相 = 180°。想象圆形跑道上的两位跑者。

Wave speed v = fλ. This equation links all three — if you know two, you get the third. The trick is to ensure consistent units: f in Hz, λ in m, v in m/s.

波速 v = fλ。此式关联三者——知二可得第三。诀窍是保证单位一致：f 用 Hz，λ 用 m，v 用 m/s。

5. Waves: Interference & Standing Waves | 波：干涉与驻波

Superposition is the principle that when two or more waves meet, the resultant displacement is the vector sum of individual displacements. Constructive interference occurs when waves are in phase (crest meets crest), producing a larger amplitude. Destructive interference occurs when waves are in antiphase (crest meets trough), minimising amplitude.

叠加原理指当两个或多个波相遇时，合位移是各分位移的矢量和。当波同相（波峰遇波峰）时发生相长干涉，产生更大振幅。当波反相（波峰遇波谷）时发生相消干涉，振幅最小。

Coherence: two sources are coherent if they emit waves with a constant phase difference and same frequency. Incoherent light cannot produce a stable interference pattern. Mnemonic: “Coherent couples cooperate constantly.”
相干性 (Coherence)：若两波源发出的波具有恒定相位差和相同频率，则它们是相干的。非相干光无法产生稳定的干涉图样。记忆法：“Coherent couples cooperate constantly.”
Path difference: difference in distance travelled by two waves. Constructive: nλ; Destructive: (n+½)λ. Think of two paths through a park — if one is exactly a wavelength longer, you’re still in step.
路程差 (Path difference)：两波传播距离的差值。相长：nλ；相消：(n+½)λ。想象公园两条小径——若一条恰好长一个波长，步伐仍一致。
Standing wave: formed when two identical waves travelling in opposite directions superpose. Nodes are points of zero displacement; antinodes are points of maximum amplitude. ‘Standing’ means the profile doesn’t move.
驻波 (Standing wave)：两列相同但反向传播的波叠加而成。波节是位移为零的点；波腹是振幅最大的点。“Standing”意为波形不移动。
Diffraction: spreading of waves when passing through a gap or around an obstacle. Significant when gap size ≈ λ. The narrower the gap, the more spread. Think of water waves entering a harbour — they bend around the breakwater.
衍射 (Diffraction)：波通过缝隙或绕过障碍物时的扩展。当缝隙尺寸≈λ 时显著。缝隙越窄，扩展越多。想象水波进入港口——绕过防波堤弯曲。

6. Quantum Physics: Photoelectric Effect | 量子物理：光电效应

The photoelectric effect refers to the emission of electrons from a metal surface when light of sufficient frequency shines on it. This phenomenon cannot be explained by the wave theory of light; it requires the photon model. The key terms here often trap students, so careful definition is vital.

光电效应指当足够频率的光照射金属表面时，电子从表面逸出的现象。光的波动理论无法解释该现象；它需要光子模型。此处的关键术语常迷惑学生，精准定义至关重要。

Photon: a quantum (packet) of electromagnetic energy. E = hf, where h is Planck’s constant. Think of a photon as a ‘light bullet’ — it hits one electron.
光子 (Photon)：电磁能量的量子（包）。E = hf，h 为普朗克常量。将光子想象成一颗“光子弹”——击中单个电子。
Work function (φ): minimum energy needed to release an electron from the metal surface. It’s like an ‘entrance fee’ for electrons to escape.
逸出功 (φ)：从金属表面释放一个电子所需的最小能量。就像电子逸出的“入场费”。
Threshold frequency (f₀): minimum frequency of light for emission. f₀ = φ/h. Below this, even intense light won’t cause emission. It’s the ‘red line’ you must cross.
阈频率 (f₀)：能产生发射的最低光频率。f₀ = φ/h。低于此频率，即使光再强也不能引起发射。这是必须跨越的“红线”。
Stopping potential (Vₛ): the potential difference needed to stop the fastest photoelectrons. e Vₛ = maximum kinetic energy. Think of it as the ‘brake voltage’.
遏止电势 (Vₛ)：阻止最快光电子所需的电势差。e Vₛ = 最大动能。可视为“刹车电压”。
Einstein’s photoelectric equation: hf = φ + ½mv²ₘₐₓ. Energy of photon = work function + max kinetic energy. The equation is simply energy accounting for one photon–one electron interaction.
爱因斯坦光电方程：hf = φ + ½mv²ₘₐₓ。光子能量 = 逸出功 + 最大动能。该方程是单光子–单电子作用的能量账本。

A common pitfall: doubling the intensity doubles the number of photons, not the energy per photon. Therefore, more intensity gives more photoelectrons, but their maximum kinetic energy stays the same. Only frequency changes the max KE.

常见误区：加倍光强加倍的是光子数量，而非单个光子能量。因此，更大光强产生更多光电子，但它们的最大动能不变。只有频率能改变最大动能。

7. Electricity: Current, PD & Resistance | 电学：电流、电势差与电阻

Electricity is often modelled with water flow analogies to make these terms stick. Current is the flow of charge, measured in amperes. One ampere is one coulomb per second. Think of it as the number of charge carriers passing a point in the circuit per second.

电学常借助水流类比来牢记术语。电流是电荷的流动，单位为安培。1安培即每秒1库仑。想象它是每秒通过电路中某点的电荷载流子数量。

Potential difference (p.d.): energy transferred per unit charge. Unit volt (J/C). It’s the ‘push’ that drives current. A high p.d. is like high water pressure.
电势差 (p.d.)：单位电荷转移的能量。单位伏特 (J/C)。它是驱动电流的“推力”。高电势差如高水压。
Electromotive force (e.m.f.): energy supplied per unit charge by a source (battery). It is a p.d. when no current flows, but always associated with energy conversion. ‘Electromotive’ literally means moving electricity.
电动势 (e.m.f.)：电源（电池）提供给每单位电荷的能量。无电流时，它等于端电压，但总与能量转换相关。“Electromotive”字面意思即“驱动电的”。
Resistance: opposition to current. R = V/I. Unit ohm (Ω). The higher the resistance, the harder it is for charge to flow. Think of a narrow pipe in the water analogy.
电阻 (Resistance)：对电流的阻碍。R = V/I。单位欧姆 (Ω)。电阻越大，电荷流动越难。类比水流的窄管。
Ohm’s law: current is proportional to p.d. at constant temperature. Not all components obey it; those that do are ‘ohmic’. The law is about proportionality, not just the equation V=IR.
欧姆定律 (Ohm’s law)：恒温下电流与电势差成正比。并非所有元件都遵循；遵循的称为“欧姆元件”。该定律关乎比例关系，而不仅是等式 V=IR。
Resistivity (ρ): intrinsic property of a material. R = ρL/A. It tells you how much a material resists current regardless of shape. Low resistivity = good conductor. Remember: ‘ρ’ for ‘resistance per unit geometry’.
电阻率 (ρ)：材料的固有性质。R = ρL/A。它表明材料本身对电流的阻碍程度，与形状无关。低电阻率 = 良导体。记忆：“ρ”代表“单位几何形状的电阻”。

8. Electricity: Circuits & Components | 电学：电路与元件

Circuit rules are best learned as conservation laws. Kirchhoff’s first law: sum of currents entering a junction = sum leaving. This is charge conservation. Second law: sum of e.m.f.s = sum of p.d.s around a closed loop. This is energy conservation. Always start by drawing arrows to assign current directions.

电路规律最好作为守恒定律来学习。基尔霍夫第一定律：流入节点的电流之和 = 流出之和。这是电荷守恒。第二定律：闭合回路中电动势之和 = 电势差之和。这是能量守恒。解题时先画箭头标定电流方向。

Internal resistance (r): resistance inside a battery. Terminal p.d. V = ε − Ir. The lost volts (Ir) heat the battery. Think of a clogged pump.
内阻 (r)：电池内部的电阻。端电压 V = ε − Ir。损耗电压 (Ir) 使电池发热。想象阻塞的水泵。
Potential divider: a circuit that splits voltage. Two resistors in series produce an output Vₒᵤₜ = Vᵢₙ × R₂/(R₁+R₂). Used in sensors. ‘Divider’ means it divides voltage.
分压器 (Potential divider)：分割电压的电路。两串联电阻输出电压 Vₒᵤₜ = Vᵢₙ × R₂/(R₁+R₂)。用于传感器。“Divider”即分割者。
LDR (Light-dependent resistor): resistance decreases as light intensity increases. Think ‘LDR loves darkness, resistance rises’.
光敏电阻 (LDR)：电阻随光强增加而减小。口诀：“LDR 喜暗，暗则阻大”。
Thermistor: resistance decreases as temperature increases (NTC type). Think ‘Negative Temperature Coefficient — temp up, resistance down’.
热敏电阻 (Thermistor)：电阻随温度升高而减小（NTC 型）。口诀：“负温度系数——温升阻降”。
Diode: allows current in one direction only. Forward-biased conducts, reverse-biased blocks. The arrow in the symbol shows allowed direction.
二极管 (Diode)：只允许单向电流。正向偏置导通，反向偏置截止。符号中的箭头指示允许方向。

9. Particle Physics: Atomic Structure | 粒子物理：原子结构

The nuclear model explains that most of the mass is in a tiny, positive nucleus, surrounded by electrons. Simple terms, but precise language is needed. For example, ‘nucleon’ refers to a proton or neutron collectively; ‘nuclide’ is a species of nucleus with specific numbers of protons and neutrons.

原子核模型指出，大部分质量集中于微小的正电原子核，电子绕核运动。术语简单但需精准。例如，“核子”统称质子或中子；“核素”指具有特定质子数和中子数的原子核种类。

Atomic (proton) number Z: number of protons. Defines the element. Z for ‘Zahl’ (German for number).
原子序数 Z：质子数。决定元素种类。Z 源于德语“Zahl”（数字）。
Mass (nucleon) number A: total protons + neutrons. A ≈ relative atomic mass in u. A for ‘All nucleons’.
质量数 A：质子与中子总数。A ≈ 相对原子质量（u）。联想 A for “All nucleons”（全部核子）。
Isotope: same proton number, different neutron number. Same chemical properties, different mass. ‘Iso’ = same, ‘tope’ = place (same place on periodic table).
同位素 (Isotope)：质子数同、中子数异。化学性质相同，质量不同。’Iso’=同，’tope’=位置（周期表中同一位置）。
Fundamental particles: quarks and leptons (electrons are leptons). Hadrons are made of quarks (protons, neutrons). Baryons are 3 quarks; mesons are quark-antiquark.
基本粒子：夸克与轻子（电子属轻子）。强子由夸克构成（质子、中子）。重子含 3 夸克；介子含夸克-反夸克对。
Antimatter: each particle has an antiparticle with same mass but opposite charge (and other quantum numbers). The positron is the anti-electron.
反物质 (Antimatter)：每个粒子都有相应的反粒子，质量相同，电荷相反（还有其他量子数相反）。正电子是电子的反粒子。

The Standard Model organises all known elementary particles. Knowing the families helps answer questions on particle interactions and conservation laws like baryon number and lepton number.

标准模型对所有已知基本粒子进行分类。了解家族有助于回答有关粒子相互作用以及重子数、轻子数等守恒律的问题。

10. Waves & Quantum: Spectra & Energy Levels | 波与量子：光谱与能级

Excited atoms emit photons when electrons drop to lower energy levels. The energy of the photon equals the difference between energy levels: ΔE = E₂ − E₁ = hf. Absorption spectra show dark lines where frequencies have been absorbed. Emission spectra show bright lines on a dark background.

受激原子的电子跃迁到低能级时发射光子。光子能量等于能级差：ΔE = E₂ − E₁ = hf。吸收光谱在吸收频率处呈现暗线。发射光谱在暗背景上呈现亮线。

Ground state: the lowest energy level of an atom (n=1). Electrons fall towards it and release light. ‘Ground’ is the floor where everything settles.
基态 (Ground state)：原子的最低能级 (n=1)。电子向它跌落并放出光。“Ground”是地板，万物安歇之处。
Excitation: electron moves to a higher energy level. Can happen via photon absorption or collision. Think of an ‘excited’ child jumping up a step.
激发 (Excitation)：电子跃迁到更高能级。可通过光子吸收或碰撞实现。想象一个“兴奋的”孩子跳上台阶。
Ionisation energy: energy needed to remove an electron from the ground state to infinity (free the electron). It’s the ‘escape energy’. Higher energy than excitation.
电离能 (Ionisation energy)：将电子从基态移至无穷远（释放电子）所需的能量。即“逃脱能量”。比激发能高。
Continuous spectrum: produced by hot, dense objects (e.g. filament bulb). Contains all wavelengths.
连续光谱 (Continuous spectrum)：由热稠密物体（如白炽灯）产生。包含所有波长。
Line spectrum: produced by low-pressure gases. Unique to each element — a ‘fingerprint’.
线状光谱 (Line spectrum)：由低压气体产生。每种元素独一无二——犹如“指纹”。

11. Practical Skills & Measurement Terminology | 实验技能与测量术语

Examiners love asking about accuracy, precision, resolution, and error. These are NOT synonyms. Accuracy refers to how close a measurement is to the true value. Precision refers to how close repeated measurements are to each other, regardless of truth. A precise archer always hits the same spot, but if it’s not the bullseye, they are precise but not accurate.

考官爱问准确度、精密度、分辨率和误差。它们并非同义词。准确度指测量值接近真值的程度。精密度指重复测量值彼此接近的程度，与真值无关。一个精密的射手总是射中同一点，但若非靶心，则精密度高而准确度低。

Resolution: the smallest change an instrument can detect. For a ruler it is 1 mm; for a digital meter it is the last digit. It sets the precision limit.
分辨率 (Resolution)：仪器能检测到的最小变化。直尺为 1 mm；数字电表为最后一位数字。它限定了精密度。
Systematic error: an error that shifts all readings by a fixed amount (e.g., zero error). It affects accuracy, not precision. Correct by calibration or subtracting zero error.
系统误差 (Systematic error)：使所有读数固定偏移的误差（如零点误差）。影响准确度，不影响精密度。通过校准或减去零点误差来修正。
Random error: unpredictable scatter due to human limitations or environmental fluctuations. Affects precision. Reduced by taking multiple readings and averaging.
随机误差 (Random error)：由人为局限或环境波动引起的不可预测的散布。影响精密度。通过多次读数取平均来减小。
Uncertainty: the range within which the true value is expected to lie. Often ± half the smallest scale division for analogue instruments. Combine uncertainties in calculations using absolute or percentage forms.
不确定度 (Uncertainty)：真值预期落入的范围。模拟仪器常为±最小刻度的一半。计算中通过绝对或百分比形式合成不确定度。
Repeatability and reproducibility: repeatable: same person, same equipment, short time. Reproducible: different people, different equipment. Both assess precision in different contexts.
重复性与再现性 (Repeatability & Reproducibility)：重复性：同一人、同一设备、短时间。再现性：不同人、不同设备。两者在不同情境下评估精密度。

Graphical analysis: a straight line through the origin means the variables are directly proportional. A straight line not through origin means they are linearly related but not proportional. Use the phrase ‘directly proportional’ only when y ∝ x, i.e., line passes through (0,0).

图像分析：过原点的直线表示变量成正比。不过原点的直线表示线性相关但非正比。仅当 y ∝ x 即直线过 (0,0) 时，才用“成正比”。

12. Memory Techniques Summary | 记忆方法总结

To lock in these terms, actively engage with the word itself. Break it down into roots (Latin, Greek) when possible. Use mnemonic acronyms and visual stories. Create a glossary where you write the term, a concise definition in your own words, and an analogy or diagram. Test yourself by covering the definition and recalling it aloud. Finally, use flashcards for the pairs that are easily confused — like elastic limit vs limit of proportionality, or accuracy vs precision.

要牢记这些术语，主动与单词本身互动。尽可能拆解词根（拉丁、希腊）。使用首字母缩略词和视觉故事。创建术语表，写下术语、用自己的话给出的简洁定义，以及一个类比或简图。自测时遮住定义并口头回忆。最后，对容易混淆的概念对——如弹性极限与比例极限、或准确度与精密度——使用抽认卡。

Consistent revision of terminology not only secures easy marks in definition questions but also deepens conceptual understanding, allowing you to write clearer explanations. In Edexcel Year 12 Physics, the precise use of language is a skill as important as calculation. Keep this guide handy, and treat every term as a key that unlocks a physical idea.

持续复习术语不仅确保定义题的易得分，还加深概念理解，使你写出更清晰的解释。在 Edexcel Year 12 物理中，准确使用语言是与计算同等重要的技能。随身带着这份指南，将每个术语视为打开物理思想的钥匙。
