4. Energy | 能量
Energy is a unifying concept in physics. In Topic 1, students explore energy stores and systems, energy transfers, power, efficiency and national and global energy resources. The key stores are kinetic, gravitational potential, elastic potential, thermal, chemical, nuclear, magnetic and electrostatic.
能量是物理学中的一个统一概念。在主题 1 中，学生探索能量储存和系统、能量转移、功率、效率以及国内和全球能源资源。主要的储存形式有动能、重力势能、弹性势能、热能、化学能、核能、磁能和静电势能。
Calculations must use standard equations. For kinetic energy and gravitational potential energy, the formulas are:
Eₖ = ½ m v²
Eₚ = m g h
Where m is mass (kg), v is speed (m/s), g is gravitational field strength (9.8 N/kg on Earth), and h is height (m). Students also need to handle elastic potential energy (Eₑ = ½ k e²), power (P = E / t and P = W / t), and energy efficiency.
其中 m 为质量（千克），v 为速度（米/秒），g 为引力场强（地球上为 9.8 N/kg），h 为高度（米）。学生还需掌握弹性势能 (Eₑ = ½ k e²)、功率 (P = E / t 和 P = W / t) 以及能量效率。
Questions on renewable and non‑renewable resources require students to discuss environmental impact and reliability. The required practical on specific heat capacity uses a joulemeter or ammeter/voltmeter to measure energy transferred to a metal block, calculating ΔE = m c Δθ.
关于可再生和不可再生资源的问题要求学生讨论环境影响和可靠性。比热容的必修实验使用焦耳计或电流表/电压表来测量传递给金属块的能量，计算 ΔE = m c Δθ。
5. Electricity | 电学
Topic 2 builds on KS3 understanding of circuits. Standard symbols for circuit components must be recognised. Students must explain current, potential difference and resistance using the analogy of charge carriers and energy transfer. The fundamental equation is Ohm’s law:
主题 2 在 KS3 电路知识的基础上展开。必须认识标准电路元件符号。学生需要利用电荷载体和能量转移的类比来解释电流、电势差和电阻。基本方程是欧姆定律：
V = I R
where V is potential difference (V), I is current (A) and R is resistance (Ω). Series and parallel circuits are analysed in terms of current, voltage and total resistance. Resistive heating is described by P = I V and P = I² R.
其中 V 为电势差（伏特），I 为电流（安培），R 为电阻（欧姆）。串联和并联电路要从电流、电压和总电阻的角度进行分析。电阻加热用 P = I V 和 P = I² R 描述。
Mains electricity in the UK (230 V, 50 Hz) is covered, including alternating/direct current distinction, three-pin plug wiring, and safety features such as fuses and earth wires. The required practicals on I–V characteristics involve plotting graphs for a fixed resistor, filament lamp and diode at constant temperature. Students also investigate factors affecting resistance, notably wire length and cross-sectional area.

本主题涵盖密度、物质状态、内能、状态变化以及气体中的粒子运动。粒子模型解释了固体、液体和气体为何具有不同的性质。密度定义为 ρ = m / V。必修实验使用尺子和天平测量规则固体的密度，对于不规则物体和液体则使用排水法。
Internal energy is the sum of kinetic and potential energies of particles. Heating changes the energy stored or causes a change of state. The latent heat equations ΔE = m L (fusion or vaporisation) are examined, with attention to why temperature stays constant during changes of state.
内能是粒子动能和势能的总和。加热会改变储存的能量或引发状态变化。考查潜热方程 ΔE = m L（熔化潜热或汽化潜热），并关注为何在状态变化期间温度保持不变。
Gas pressure is explained in terms of particle collisions with container walls. The relationship between pressure and volume at constant temperature leads to the equation p V = constant. Qualitative understanding of how increasing temperature raises pressure at constant volume is required.
气体压强用粒子与容器壁的碰撞来解释。恒定温度下压强与体积的关系导出方程 p V = 常数。对于恒定体积下升高温度如何增大压强，需要定性的理解。

核裂变和核聚变涉及链式反应以及恒星和反应堆中所需的条件。铀-235 的裂变方程常涉及钡和氪同位素。聚变需要极高的温度和压力来克服静电斥力。
8. Forces | 力
Forces is a substantial topic covering scalar/vector quantities, contact/non‑contact forces, Newton’s laws, moments, pressure and elasticity. Vector resolution and free body diagrams are essential skills. The equation for resultant force is F = m a, where force is in newtons, mass in kg and acceleration in m/s².

Speed and velocity are distinguished; the kinematics equations are provided on the physics equation sheet. Typical relationships are v = u + a t, v² – u² = 2 a s and s = u t + ½ a t². The terminal velocity concept links forces with motion in fluids.
速度与速率需区分；运动学方程提供在物理方程式表上。典型关系式有 v = u + a t、v² – u² = 2 a s 和 s = u t + ½ a t²。终端速度的概念将力与流体中的运动联系起来。
Moments explain levers and gears, with the principle of moments used to solve equilibrium problems. Pressure in fluids acts equally in all directions, and the equation p = F / A is tested alongside the depth‑dependence p = h ρ g. The required practical on force and extension investigates Hooke’s Law for a spring, plotting a force‑extension graph and determining the spring constant.
力矩解释杠杆和齿轮，力矩原理用于解决平衡问题。流体中的压强在各个方向上均等作用，考查方程 p = F / A 以及压强随深度的变化 p = h ρ g。力和伸长量的必修实验探究弹簧的胡克定律，绘制力-伸长量图像并确定劲度系数。

主题 6 讨论横波和纵波的性质与应用。关键定义包括振幅、波长、频率、周期和波速。波动方程 v = f λ 应用于声波、水波和电磁波。
The electromagnetic spectrum is ordered by frequency/wavelength. Each region (radio, microwave, infrared, visible, ultraviolet, X‑ray, gamma) has specific uses and hazards. For example, X‑rays are used in medical imaging but can cause ionisation; microwaves are used for satellite communication and heating food.
电磁波谱按频率/波长排序。每一波段（无线电波、微波、红外线、可见光、紫外线、X 射线、γ 射线）都有特定的用途和危害。例如，X 射线用于医学成像但会引起电离；微波用于卫星通信和加热食物。
Reflection and refraction are studied with ray diagrams involving plane mirrors and transparent blocks. The required practicals include using a ripple tank to measure wave frequency and speed, and tracing rays through a glass block to explore refraction and critical angle. Seismic waves provide a real‑world context for P‑waves and S‑waves in Earth’s interior.

10. Magnetism and Electromagnetism | 磁与电磁
Magnetism starts with permanent and induced magnets, magnetic fields and the Earth’s magnetic field. The shape of a magnetic field is visualised using plotting compasses or iron filings. Electromagnetism explores the magnetic effect of a current‑carrying conductor; the right‑hand grip rule helps determine field direction around a straight wire or solenoid.
磁学从永久磁铁、感应磁铁、磁场和地磁场开始。磁场的形状可用指南针或铁屑可视化。电磁学探究载流导体的磁效应；右手定则有助于判断直导线或螺线管周围的磁场方向。
Fleming’s left‑hand rule is introduced for the motor effect, linking current, magnetic field and force (F = B I l for a conductor at right angles to the field). Students learn how this principle drives the operation of loudspeakers, electric motors and moving‑coil instruments.
引入弗莱明左手定则解释电动机效应，将电流、磁场和力联系起来（当导体与磁场垂直时，F = B I l）。学生将了解这一原理如何驱动扬声器、电动机和动圈式仪表。
Electromagnetic induction is the reverse: a changing magnetic field induces a p.d. in a conductor. This leads to the generator effect and the structure of an alternator and a dynamo. Transformers are analysed with the turns ratio equation Vₚ / Vₛ = Nₚ / Nₛ and the assumption of 100% efficiency for ideal transformers. National grid transmission uses step‑up and step‑down transformers to minimise power loss.
电磁感应相反：变化的磁场会在导体中感应出电势差。这引出发电机效应以及交流发电机和直流发电机的构造。分析变压器使用匝数比方程 Vₚ / Vₛ = Nₚ / Nₛ，并假设理想变压器效率 100%。国家电网输电使用升压和降压变压器来最小化功率损耗。
11. Space Physics (Triple Physics only) | 空间物理（仅限单独物理科）
Space Physics appears only in Paper 2 for Triple Science students. It covers the life cycle of stars, from nebulae to protostars, main sequence, and eventual fate as white dwarf, neutron star or black hole depending on mass. Fusion in stars creates heavier elements up to iron; supernovae scatter elements across the universe.
空间物理仅出现在 Triple Science 学生的试卷二中。内容包括恒星的生命周期，从星云到原恒星、主序星，以及根据质量最终变为白矮星、中子星或黑洞。恒星中的核聚变产生直到铁为止的重元素；超新星将这些元素散播到宇宙各处。
Orbital motion of planets, moons and artificial satellites is explained by the balance of gravity and velocity. For circular orbits, the centripetal force is provided by gravity, and velocity changes direction but not speed. The Big Bang theory and evidence from cosmic microwave background radiation and red‑shift of galaxies complete the cosmological narrative. The red‑shift relationship is described qualitatively; students use data on recession velocity and distance to support an expanding universe.
行星、卫星和人造卫星的轨道运动用引力与速度的平衡来解释。对于圆轨道，向心力由引力提供，速度改变方向但不变大小。大爆炸理论以及来自宇宙微波背景辐射和星系红移的证据完成了宇宙学的叙述。红移关系以定性方式描述；学生使用退行速度和距离的数据来支持宇宙膨胀的观点。
12. Key Mathematical and Working Scientifically Skills | 关键数学与科学方法技能
At least 30% of marks test mathematical skills at the level of GCSE Mathematics. This includes rearranging equations, recognising proportional and inversely proportional relationships, converting units, plotting graphs, determining gradients, and calculating areas under graphs. Standard form and significant figures are frequently assessed.
至少 30% 的分数考查相当于 GCSE 数学水平的数学技能。包括变形公式、识别正比与反比关系、换算单位、绘制图表、求解斜率以及计算图像下方面积。科学计数法和有效数字也经常考查。
Working scientifically is woven into every topic, with questions asking students to evaluate experimental methods, identify sources of error, propose improvements and analyse data. The required practicals are a vehicle for these skills, but unfamiliar contexts are also used to assess whether students can apply the scientific method.
科学方法技能贯穿每个主题，问题要求学生评价实验方法、识别误差来源、提出改进建议和分析数据。必修实验是这些技能的载体，但也会通过陌生情境来评估学生是否能够运用科学方法。
Students should be comfortable with variables (independent, dependent, control), repeating measurements to reduce random error, distinguishing between accuracy and precision, and explaining anomalies. Past paper practice is the most reliable way to sharpen these skills.
学生应熟练处理变量（自变量、因变量、控制变量）、通过重复测量减少随机误差、区分准确度与精密度，并能解释异常值。刷历年真题是磨练这些技能最可靠的方法。
