从低年级的普通科学课进入 Year 10 并开始学习 CIE IGCSE 物理（0625），是一次不小的跨越。暑假提供了一个宝贵的窗口，让你可以提前预习核心知识、建立科学词汇、培养自信的学习心态。这篇衔接课程文章将带你梳理重点概念、考试结构、实验技能和高效学习策略，帮助你在新学年抢占先机。
1. The Importance of Summer Preparation | 暑期预习的重要性
Many students find the step up to IGCSE Physics demanding, as it requires precise terminology, mathematical application, and logical reasoning. Engaging in structured summer study helps reduce the initial shock and builds a reliable knowledge base.
很多学生发现升上 IGCSE 物理时要求较高，因为需要准确的术语、数学应用和逻辑推理。进行有计划的暑期预习可以减轻开学初的冲击，打好扎实的知识基础。
Familiarising yourself with English-medium resources in advance strengthens your ability to read textbooks, understand exam questions, and express scientific ideas clearly without relying on translation.
提前熟悉英文学习资料，能增强你阅读教材、理解考题和清晰表达科学想法的能力，而不必依赖翻译。
Summer preparation also cultivates self-discipline and independent learning habits, which are essential for success in the two-year IGCSE course.
暑期预习还能培养自律和独立学习的习惯，这对两年 IGCSE 课程的成功至关重要。
2. Overview of the CIE IGCSE Physics (0625) Syllabus | CIE IGCSE 物理（0625）大纲概览
The CIE 0625 syllabus is organised into six main topics: Motion, forces and energy; Thermal physics; Waves; Electricity and magnetism; Nuclear physics; and Space physics. In Year 10, schools often cover the first four topics, while Nuclear and Space physics are typically taught in Year 11.
CIE 0625 大纲分为六大主题：运动、力与能量；热物理；波动；电与磁；核物理；空间物理。通常在 Year 10 会先学前四个主题，核物理和空间物理则安排在 Year 11。
Assessment consists of three papers: a multiple-choice paper (Paper 1 or 2), a theory paper with structured questions (Paper 3 or 4), and a practical paper (Paper 5 or 6). Knowing this structure early helps you tailor note-taking and revision strategies.
考试包括三份试卷：选择题卷（Paper 1 或 2）、含结构化问题的理论卷（Paper 3 或 4），以及实验卷（Paper 5 或 6）。提前了解结构有助于调整笔记和复习策略。
3. Topic 1: Motion | 运动学
Motion is described using scalar quantities like distance and speed, and vector quantities like displacement and velocity. Acceleration is the rate of change of velocity and can involve a change in speed or direction.
运动用标量（如距离和速率）和矢量（如位移和速度）来描述。加速度是速度的变化率，可以表现为速度大小或方向的变化。
Distance–time graphs show how far an object has travelled; the gradient gives speed. Velocity–time graphs are more powerful: the gradient gives acceleration, and the area under the graph gives the displacement.
距离—时间图显示物体运动的路程，其斜率表示速率。速度—时间图更有用：斜率表示加速度，图线下的面积表示位移。
For constant acceleration, you will use the following equations:
v = u + at
s = (u + v)t / 2
s = ut + ½at²
v² = u² + 2as
这些匀加速直线运动公式是解题的核心工具。
A classic application is free fall near the Earth's surface, where acceleration due to gravity g is approximately 9.8 m/s². Dropping a ball from rest lets you predict its velocity and displacement over time.
一个经典应用是地表附近的自由落体，重力加速度 g 约为 9.8 m/s²。从静止释放一个球，你可以预测它随时间变化的速度和位移。
4. Topic 2: Forces and Momentum | 力与动量
Forces can change the shape, speed, or direction of an object. Newton's first law states that an object remains at rest or in uniform motion unless acted upon by a resultant force.
力可以改变物体的形状、速度或方向。牛顿第一定律指出，除非受到合力作用，物体将保持静止或匀速直线运动状态。
Newton' al force caused by gravity, given by W = m g, where g is the gravitational field strength.
牛顿第二定律将力、质量和加速度联系起来：F = m a。重力是一种特殊的力，计算公式为 W = m g，其中 g 是引力场强度。
a closed system, the total momentum before an interaction equals the total momentum after – the principle of conservation of momentum.
动量 p 是质量与速度的乘积：p = m v。在封闭系统中，相互作用前的总动量等于相互作用后的总动量，这就是动量守恒定律。
l to force × time. This explains why crumple zones in cars reduce the force on passengers.
冲量等于动量的变化，也等于力乘以作用时间。这解释了为什么汽车的溃缩区能减小乘客受到的力。
5. Topic 3: Energy, Work and Power | 能量、功与功率
l, and others. Kinetic energy KE = ½ m v², and gravitational potential energy GPE = m g h.

ted from one form to another. Efficiency = (useful output power / total input power) × 100%.
能量守恒定律表明，能量不能被创造或消灭，只能被转移或从一种形式转化为另一种。效率 =（有用输出功率 / 总输入功率）× 100%。
f the force: W = F d. Power is the rate of doing work: P = W / t, measured in watts (J/s).
当一个力使物体沿力的方向移动时，我们就说力做了功：W = F d。功率是做功的速率：P = W / t，单位是瓦特（焦耳/秒）。
6. Topic 4: Thermal Physics | 热物理
The kinetic particle model explains states of matter: solids have closely packed vibrating particles, liquids have particles that can move past one another, and gases have fast-moving, widely spaced particles.
分子运动论可以解释物态：固体的粒子紧密堆积且只在固定位置振动，液体的粒子可以相互滑移，气体的粒子快速运动且相距很远。
Temperature is a measure of the average kinetic energy of particles, whereas internal energy is the total kinetic and potential energy of all particles in a system.
温度是粒子平均动能的量度，而内能是系统中所有粒子的动能和势能之和。
heat is the energy absorbed or released during a change of state at constant temperature.
比热容 c 将能量变化与质量、温度变化联系起来：Q = m c Δθ。潜热是物质在温度不变的状态变化过程中吸收或释放的能量。
Heat transfer occurs via conduction (mainly in solids), convection (in fluids), and radiation (infrared, which can travel through a vacuum). Understanding these helps explain everyday phenomena like sea breezes and vacuum flasks.
热传递的方式有传导（主要在固体中）、对流（在流体中）和辐射（红外线，可在真空中传播）。理解这些有助于解释海陆风和保温瓶等日常现象。
7. Topic 5: Waves | 波动
Waves transfer energy without transferring matter. Transverse waves (e.g., light, water ripples) have oscillations perpendicular to the direction of travel; longitudinal waves (e.g., sound) have oscillations parallel to the direction.
波动传递能量而不传递物质。横波（如光、水波）的振动方向与传播方向垂直；纵波（如声波）的振动方向与传播方向平行。

Reflection, refraction, and diffraction are characteristic wave behaviours. Refraction occurs when waves change speed at a boundary, causing a change in direction unless the incidence is normal.
反射、折射和衍射是波的特征行为。折射发生在波在界面处改变速度时，除非垂直入射，否则方向也会改变。

Resistance R = V / I measures how difficult it is for current to flow. Ohm's law states that, for a resistor at constant temperature, V ∝ I. Resistors can be combined in series (Rtotal = R₁ + R₂ + ...) and parallel (1/Rtotal = 1/R₁ + 1/R₂ + ...).
电阻 R = V / I 衡量电流通过的难易程度。欧姆定律指出，在温度不变时，电阻两端的电压与电流成正比。电阻可以串联（Rₜₒₜₐₗ = R₁ + R₂ + …）和并联（1/Rₜₒₜₐₗ = 1/R₁ + 1/R₂ + …）。
ese relations are essential for understanding how energy is dissipated in home appliances.
电路中的电功率可以用 P = I V = I² R = V² / R 计算。这些关系对理解家用电器如何消耗能量至关重要。
Magnets have north and south poles; like poles repel, unlike poles attract. An electromagnet is created by passing a current through a coil, and its strength can be increased by adding an iron core or more turns.
磁铁有 N 极和 S 极；同名磁极相斥，异名相吸。电流通过线圈可以产生电磁铁，增加铁芯或线圈匝数可以增强其磁场。

Isotopes are atoms of the same element with different numbers of neutrons. Some isotopes are unstable and undergo radioactive decay, emitting alpha (α), beta (β), or gamma (γ) radiation.
同位素是同种元素中中子数不同的原子。有些同位素不稳定，会发生放射性衰变，放出 α、β 或 γ 射线。
Alpha particles are helium nuclei, beta particles are fast electrons (or positrons), and gamma rays are high-energy electromagnetic waves. Their penetrating powers and ionising abilities differ significantly.
α 粒子是氦核，β 粒子是高速电子（或正电子），γ 射线是高能电磁波。它们的穿透能力和电离本领差异很大。
Half-life is the time taken for half the nuclei in a radioactive sample to decay. This concept is crucial for applications like radioactive dating and medical tracers.
半衰期是放射性样品中一半原子核发生衰变所需的时间。这一概念在放射性测年和医用示踪剂等应用中十分关键。

11. Developing Practical and Inquiry Skills | 培养实验与探究技能
Practical work is assessed through Paper 5 (Practical Test) or Paper 6 (Alternative to Practical). You need to be confident in taking measurements with instruments such as rulers, stopwatches, ammeters, voltmeters, and micrometer screw gauges.
实验能力的考查通过 Paper 5（实验操作考试）或 Paper 6（实验替代笔试）进行。你需要熟练使用刻度尺、秒表、电流表、电压表和千分尺等仪器进行测量。
Every measurement has uncertainty. You should take repeat readings, calculate an average, and determine the range or half-range as an estimate of uncertainty. Graphs should have labelled axes with units, sensible scales, and best-fit lines.
任何测量都存在不确定度。你应该进行多次测量、计算平均值，并用极差或半极差估算不确定度。绘制图表时要有带单位的坐标轴、合理的刻度和最佳拟合线。
