大纲还包含实验评估——要么是试卷5（实验考试），要么是试卷6（实验替代）。你所在的学校将决定采取哪种方式。
2. Bridging from Year 9 to Year 10 | 从九年级到十年级的衔接
In Year 9, you may have studied general science with some physics topics such as forces, energy, and simple circuits. Year 10 Physics goes into greater depth and introduces more quantitative work, including equations and graphs.
在九年级，你可能学习了包含物理内容的综合科学，如力、能量和简单电路。十年级物理会更加深入，并引入更多定量计算，包括方程和图表。
It is important to strengthen your mathematical foundations: algebra, rearranging equations, using standard form, and interpreting graphs. Make sure you are comfortable with these skills early on.
加强数学基础很重要：代数、方程变形、科学记数法以及解读图表。尽早确保自己熟练掌握这些技能。
You will also start using more precise scientific vocabulary. Words like ‘velocity’, ‘acceleration’, ‘resultant force’, and ‘potential difference’ need to be used accurately.
你还会开始使用更精确的科学词汇。像“速度”、“加速度”、“合力”、“电势差”等术语需要准确运用。
3. Key Topics in Year 10 Physics | 十年级物理的关键主题
Year 10 typically covers a large portion of the syllabus. Some of the core topics include motion, forces, energy, thermal physics, and waves. Let’s look at them briefly.
十年级通常涵盖大部分大纲内容。一些核心主题包括运动、力、能量、热物理和波动。我们简要了解一下。
Motion: You learn to describe motion using distance, displacement, speed, velocity, and acceleration. Key equations are v = s / t, a = (v – u) / t, and the equations of motion for uniform acceleration.
运动：学会用路程、位移、速率、速度和加速度描述运动。关键方程有 v = s / t，a = (v – u) / t 以及匀加速运动方程。
Forces: Newton’s laws, resultant forces, friction, mass and weight, and turning effects (moments). The equation F = m × a is fundamental.
力：牛顿定律、合力、摩擦力、质量与重量、以及转动效应（力矩）。方程 F = m × a 是基础。
Energy: Forms of energy, energy transfers, work done (W = F × d), power (P = W / t), and efficiency. Kinetic energy Eₖ = ½ m v² and gravitational potential energy Eₚ = m g h.
能量：能量形式、能量转移、做功（W = F × d）、功率（P = W / t）和效率。动能 Eₖ = ½ m v²，重力势能 Eₚ = m g h。
Thermal physics: Temperature, heat capacity, specific heat capacity, latent heat, and gas laws. Calculation of thermal energy Q = m c Δθ is common.
热物理：温度、热容量、比热容、潜热和气体定律。热能计算 Q = m c Δθ 很常见。
Waves: Properties of waves, reflection, refraction, diffraction, and the electromagnetic spectrum. You need to use the wave equation v = f λ.
波动：波的性质、反射、折射、衍射和电磁波谱。需要运用波动方程 v = f λ。
4. Mathematical Skills Required | 所需的数学技能
CAIE IGCSE Physics involves a lot of calculations. You must be able to substitute values into formulas, rearrange equations to find an unknown quantity, and give answers to an appropriate number of significant figures.
CAIE IGCSE 物理包含大量计算。你必须能够将数值代入公式、对方程进行变形求未知量，并以适当的有效数字给出答案。
Here is a table of some essential equations you will encounter in Year 10:
以下是十年级会遇到的一些重要公式表格：
| Quantity | Equation | Units |
|---|---|---|
| Speed / velocity | v = s / t | m/s |
| Acceleration | a = (v – u) / t | m/s² |
| Force | F = m × a | N |
| Density | ρ = m / V | kg/m³ |
| Pressure | p = F / A | Pa |
| Work done | W = F × d | J |
| Power | P = W / t | W |
| Kinetic energy | Eₖ = ½ m v² | J |
| Gravitational potential energy | Eₚ = m g h | J |
| Efficiency | Efficiency = (useful output / total input) × 100% | % |
Practice using these equations in different contexts. Pay attention to unit conversions, such as cm to m, minutes to seconds, and g to kg.
在各种情境下练习使用这些公式。注意单位换算，例如厘米转换为米、分钟转换为秒、克转换为千克。
Graph skills are also tested: plotting points, drawing lines of best fit, calculating gradients, and finding intercepts. Make sure you understand what a straight-line graph tells you about relationships between variables.
图表技能也会考查：描点、画最佳拟合线、计算斜率和找出截距。确保你理解一条直线图如何反映变量间的关系。
5. Practical Skills and Investigations | 实验技能与探究
Physics is an experimental science. Your course will involve practical work, and you need to be familiar with common apparatus such as rulers, stopwatches, ammeters, voltmeters, and oscilloscopes.
物理是一门实验科学。你的课程将包含实验操作，你需要熟悉常用器材，如直尺、秒表、电流表、电压表和示波器。
You should know how to plan an investigation: identifying variables (independent, dependent, control), making measurements, repeating readings for reliability, and dealing with anomalies.
你应知道如何规划一项探究：确定变量（自变量、因变量、控制变量），进行测量，重复读数以确保可靠性，并处理异常数据。
For the alternative to practical paper, you’ll be asked to interpret data from experiments, draw conclusions, and evaluate methods. Practice describing sources of error and suggesting improvements.
对于实验替代试卷，你会被要求解释实验数据、得出结论并评估方法。练习描述误差来源并提出改进建议。
Key practical topics in Year 10 include: measuring speed and acceleration, investigating forces and extension of springs (Hooke’s law), determining density, and finding the refractive index of a glass block.
十年级的关键实验主题包括：测量速度和加速度、探究力和弹簧伸长（胡克定律）、测定密度、以及测量玻璃砖的折射率。
