1. CCEA GCSE Physics Structure | CCEA GCSE 物理课程结构
The CCEA GCSE Physics course is divided into three externally assessed units. Year 10 typically covers most of Unit 1 and an introduction to Unit 2. Unit 1 focuses on motion, forces, moments, energy, density, kinetic theory, and radioactivity. Unit 2 encompasses waves, light, electricity, magnetism, electromagnetism, and space physics. Unit 3 is a practical skills unit, assessed by a written exam based on prescribed practical tasks.
CCEA 的 GCSE 物理课程分为三个外部考核单元。Year 10 通常涵盖第一单元的大部分内容和第二单元的入门知识。第一单元重点包括运动、力、力矩、能量、密度、分子动理论和放射性。第二单元则包含波、光、电学、磁学、电磁学和空间物理。第三单元为实验技能单元，通过一份基于规定实验任务的笔试进行评估。
Understanding this structure helps students navigate the syllabus effectively. In Year 10, schools often deliver the fundamental topics sequentially, integrating theory with hands-on practical work to develop scientific enquiry skills as outlined in the specification.
了解这一结构有助于学生高效地掌握大纲。在 Year 10，学校通常按序讲授这些基础课题，将理论知识与动手实验相结合，以培养大纲规定的科学探究技能。
2. Motion, Forces, and Moments | 运动、力与力矩
Motion is described using scalar quantities like distance and speed, and vector quantities like displacement and velocity. The key equations for uniform acceleration are derived from definitions. A fundamental equation is v = u + at, where v is final velocity, u is initial velocity, a is acceleration, and t is time.
运动通过路程、速率等标量以及位移、速度等矢量来描述。匀加速运动的核心公式源于定义。其中一个基本方程为 v = u + at，其中 v 为末速度，u 为初速度，a 为加速度，t 为时间。
v = u + a t
Force analysis involves Newton’s three laws. The resultant force determines acceleration through F = m a (force = mass × acceleration). Students must be able to draw free-body diagrams, resolve forces, and calculate moments, where moment = force × perpendicular distance from the pivot.
力的分析涉及牛顿三大定律。合力通过 F = m a（力 = 质量 × 加速度）决定加速度。学生必须能绘制隔离体图、分解力，并计算力矩，力矩 = 力 × 到支点的垂直距离。
F = m a
Momentum is introduced as a measure of mass in motion, p = m v. The principle of conservation of momentum is applied in collisions and explosions, a common context for numerical problems in the CCEA exam.
动量作为质量运动的度量被引入，p = m v。动量守恒定律应用于碰撞和爆炸，这是 CCEA 考试中常见的计算题背景。
p = m v
3. Energy Resources and Energy Transfer | 能源与能量传递
Energy can be stored in kinetic, gravitational potential, elastic potential, thermal, chemical, and nuclear forms. The kinetic energy Eₖ = ½ m v² and gravitational potential energy Eₚ = m g h are the two most frequently used equations in Year 10.
能量可以储存在动能、重力势能、弹性势能、热能、化学能和核能等形式中。动能 Eₖ = ½ m v² 和重力势能 Eₚ = m g h 是 Year 10 最常用的两个公式。
Eₖ = ½ m v²
Eₚ = m g h
The principle of conservation of energy states that energy cannot be created or destroyed, only transferred. Sankey diagrams are used to visualise energy transfers and calculate efficiency as useful output / total input × 100%.
能量守恒定律指出，能量既不能凭空产生，也不能凭空消失，只能转移。桑基图用于直观展示能量传递，并计算效率 = 有用输出 / 总输入 × 100%。
Work done is the product of force and distance moved in the direction of the force, W = F d. Power is the rate of energy transfer, P = E / t, measured in watts. Linking these concepts is essential for solving complex problems.
功是力与沿力方向移动距离的乘积，W = F d。功率是能量传递的速率，P = E / t，单位为瓦特。将这些概念联系起来对于解决复杂问题至关重要。
The CCEA course also explores renewable and non-renewable energy resources, including wind, solar, tidal, fossil fuels, and nuclear, focusing on their environmental impact and sustainability within Northern Ireland’s energy mix.

Kinetic theory explains matter in terms of particle motion. The properties of solids, liquids, and gases are described by particle arrangement and energy. Internal energy is the sum of kinetic and potential energies of particles, and changes of state occur without temperature change while internal energy alters.
分子动理论从粒子运动的角度解释物质。固体、液体和气体的性质由粒子的排列和能量描述。内能是粒子动能与势能的总和，物态变化时温度不变而内能发生改变。
Pressure in fluids acts equally in all directions. The pressure due to a liquid column is given by p = ρ g h. Atmospheric pressure and its measurement using a manometer or barometer are included, with application to everyday situations like hydraulics.
流体中的压强在各个方向上均匀作用。液柱产生的压强公式为 p = ρ g h。大气压及其使用压力计或气压计的测量方法也包含在内，并应用于液压等日常场景。
5. Waves: Sound and Light | 波：声与光
Waves transfer energy without transferring matter. The wave speed equation v = f λ relates speed, frequency, and wavelength. Both transverse and longitudinal waves are studied: light and water waves are transverse; sound and seismic P-waves are longitudinal.

太阳系由太阳、行星、卫星、矮行星、小行星和彗星组成。轨道运动靠万有引力提供所需向心力维持。学生计算轨道速度，并将其与开普勒的观测联系起来。
The life cycle of a star depends on its mass. Low-mass stars like our Sun evolve from protostar → main sequence → red giant → white dwarf. High-mass stars become super red giants, then undergo supernova, forming neutron stars or black holes.
恒星的演化历程取决于其质量。像太阳这样的低质量恒星经历原恒星 → 主序星 → 红巨星 → 白矮星的过程。大质量恒星变成超红巨星，随后发生超新星爆发，形成中子星或黑洞。
