1. Paper Structure and Command Words | 试卷结构与指令词

PH01 is a written paper of 1 hour 30 minutes, carrying 80 marks, and it contributes 50% of the International AS qualification. The paper begins with a substantial multiple-choice section and then moves to structured calculation and explanation questions. Candidates must show all working; a correct final answer with no method usually loses method marks.

PH01 为笔试，时长 1 小时 30 分钟，满分 80 分，占国际 AS 资格的 50%。试卷先是一大段单项选择题，随后转入结构化计算与解释题。考生必须写出全部过程；仅有正确最终答案而没有方法通常得不到方法分。

Command words determine how marks are awarded. ‘State’ requires a single word, phrase or value with no working. ‘Calculate’ requires a numerical answer with working, correct units and suitable significant figures. ‘Show that’ requires a substitution and a final value rounded to no more than one or two significant figures. ‘Explain’ requires a causal link, not just a description.

指令词决定分数如何分配。「State（写出）」只需一个词、短语或数值，不需要过程。「Calculate（计算）」需要写出过程、数值答案、正确单位和合适有效数字。「Show that（证明）」需要代入数值并把结果修约到不超过一或两位有效数字。「Explain（解释）」需要因果关系，而不仅仅是描述。

Command Word	Required Answer
State	A value, word or formula, no working
Calculate	Working, answer, unit, significant figures
Show that	Substitution and rounded value, typically 2 or 3 s.f.
Explain	Phenomenon linked to physics principle

2. Measurements and Uncertainties | 测量与不确定度

The June 2023 paper rewarded candidates who could convert prefixes quickly and quote uncertainties correctly. SI prefixes appear throughout the paper: nano (10⁻⁹), micro (10⁻⁶), milli (10⁻³), centi (10⁻²), kilo (10³) and mega (10⁶). A mistake here, for example writing cm as m without dividing by 100, costs both numerical and unit marks.

2023年6月卷对能快速转换词头并正确写出不确定度的考生非常友好。整份试卷都会用到 SI 词头：纳（10⁻⁹）、微（10⁻⁶）、毫（10⁻³）、厘（10⁻²）、千（10³）、兆（10⁶）。这里犯错的例子包括把 cm 直接当成 m 而未除以100，会同时丢失数值分和单位分。

For a single reading, the uncertainty is often taken as half the smallest scale division on an analogue instrument and as one digit on a digital instrument. When quantities are added or subtracted, absolute uncertainties add. When quantities are multiplied or divided, percentage uncertainties add.

对于单次读数，模拟仪器的不确定度通常取最小分度的一半，数字仪器取末位数字。当物理量相加或相减时，绝对不确定度相加；当物理量相乘或相除时，百分比不确定度相加。

percentage uncertainty = (Δx / x) × 100%

For a quantity raised to a power n, the percentage uncertainty is multiplied by n. For example, if the uncertainty in radius r is 2%, then the uncertainty in r³ is 6%. In the exam, always state absolute and fractional uncertainties in the same units, and do not quote a final uncertainty to more than one significant figure.

当物理量乘方为 n 次时，百分比不确定度乘以 n。例如，若半径 r 的不确定度为 2%，则 r³ 的不确定度为 6%。考试中，绝对不确定度与分式不确定度必须使用相同单位，最终不确定度不要超出一位有效数字。

3. Kinematics and Projectile Motion | 运动学与抛体运动

Kinematics questions examine the difference between vector and scalar quantities, the use of displacement–time and velocity–time graphs, and the SUVAT equations. The gradient of a displacement–time graph is velocity; the gradient of a velocity–time graph is acceleration; the area under a velocity–time graph is displacement.

运动学考题考查矢量与标量的区别、位移–时间图与速度–时间图的应用，以及 SUVAT 方程组。位移–时间图的斜率是速度；速度–时间图的斜率是加速度；速度–时间图下的面积是位移。

The SUVAT equations below are only valid for uniform (constant) acceleration. Always check the units of u, v, s, a and t before substitution — a common trap is using minutes instead of seconds.

以下 SUVAT 方程仅适用于匀变速运动。代入前务必检查 u、v、s、a、t 的单位——常见陷阱是把分钟当成秒。

v = u + at

s = ut + ½at²

v² = u² + 2as

Projectile motion is best treated by splitting the motion into vertical and horizontal components. The horizontal component of acceleration is zero, so horizontal velocity stays constant. The vertical component has acceleration g = 9.81 m s⁻² downward. The time of flight is controlled purely by the vertical motion; use this same time in the horizontal displacement equation s = vₓ × t.

抛体运动最好的处理方式是拆分为竖直与水平两个分量。水平方向加速度为零，水平速度保持不变。竖直方向加速度为 g = 9.81 m s⁻² 向下。飞行时间完全由竖直运动决定；把这一时间代入水平位移公式 s = vₓ × t 即可。

A common June 2023 error was treating the initial velocity as purely horizontal. If a projectile is launched at an angle θ to the horizontal, the components are uₓ = u cos θ and uᵧ = u sin θ, and each component must be substituted into its own equation.

2023年6月卷的常见错误是把初速度完全当作水平方向。当抛射物以与水平方向夹角 θ 发射时，分量为 uₓ = u cos θ、uᵧ = u sin θ，每个分量必须代入相应的方程。

4. Forces and Newton’s Laws | 力与牛顿定律

Newton’s three laws are tested both conceptually and numerically. The first law states that a body remains at rest or moves with constant velocity unless acted on by a resultant force. The second law gives F = ma, which is used in almost every force calculation. The third law states that forces always occur in equal and opposite pairs acting on different bodies.

牛顿三定律既考概念也考计算。第一定律：物体在不受合外力时保持静止或匀速直线运动。第二定律：F = ma，几乎所有受力计算都会用到。第三定律：力总是成对出现，大小相等、方向相反，且作用在不同物体上。

F = ma

W = mg

Weight and mass are frequently confused. Mass is a measure of the amount of matter in kilograms; weight is the gravitational force in newtons. On a slope inclined at angle θ, the weight component acting down the slope is mg sin θ and the component normal to the slope is mg cos θ.

重量与质量经常被混淆。质量以千克度量物质的多少；重量则是牛顿为单位的引力大小。在倾角为 θ 的斜面上，沿斜面向下的分量是 mg sin θ，垂直斜面的分量是 mg cos θ。

Moments also appeared in the June 2023 analysis: the moment of a force about a pivot is M = F × d, where d is the perpendicular distance from the pivot to the line of action. For a body in equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments about any pivot.

力矩也出现在2023年6月的考查范围内：力对支点的力矩为 M = F × d，其中 d 是支点到力的作用线的垂直距离。物体平衡时，绕任意支点的顺时针力矩之和等于逆时针力矩之和。

M = F × d

Always draw a free-body diagram before solving force problems. Label the forces clearly: weight acts vertically downward, the normal reaction acts perpendicular to the surface, and friction acts parallel to the surface opposing motion.

求解受力问题前先画受力分析图。清楚标注各力：重力竖直向下，法向支持力垂直于接触面，摩擦力平行于接触面并阻碍运动。

5. Work, Energy and Power | 功、能与功率

The principle of conservation of energy states that energy cannot be created or destroyed, only transferred. In mechanics questions, the total initial energy (kinetic + gravitational potential + elastic) plus any work done by driving forces equals the total final energy plus energy dissipated as heat due to friction or air resistance.

能量守恒定律指出：能量不能凭空产生或消灭，只能转移。在力学题中，初始总能（动能 + 重力势能 + 弹性势能）加上驱动力做功，等于末总能加上因摩擦或空气阻力耗散的热能。

W = F × s × cosθ

Ek = ½mv²

Ep = mgh

Work is done when a force moves its point of application through a distance. If the force is not parallel to the displacement, use the component of force along the direction of motion, F cos θ. The area under a force–distance graph gives the work done.

做功发生在力使其作用点移动一段距离的过程中。若力与位移不平行，应使用力在运动方向上的分量 F cos θ。力–距离图像下的面积表示做功大小。

Power is the rate of doing work. When a constant force F acts on an object moving at velocity v, the power is P = Fv. Efficiency is the ratio of useful output energy to total input energy, often written as a percentage.

功率是做功的快慢。当恒力 F 作用于以速度 v 运动的物体时，功率为 P = Fv。效率是有用输出能量与总输入能量之比，通常写成百分比。

P = W / t = Fv

In June 2023, several candidates forgot to include the change in kinetic energy when calculating the work done against gravity on a slope. The vertical height h, not the sloping distance, must be used in Ep = mgh.

在2023年6月的考试中，不少考生在计算沿斜面克服重力做功时忘了考虑动能变化。Ep = mgh 中的 h 必须取竖直高度，而不是斜面长度。

6. Electricity: Circuits and Resistivity | 电学：电路与电阻率

Electricity contributes a large fraction of PH01 marks. Charge and current are linked by Q = It, where current is the rate of flow of charge. Ohm’s law states that for a metallic conductor at constant temperature, the potential difference across it is proportional to the current through it.

电学在 PH01 中占分很大。电荷与电流的关系为 Q = It，电流是电荷流动的速率。欧姆定律指出：对于温度恒定的金属导体，其两端电压与流过它的电流成正比。

Q = I × t

V = I × R

For resistors in series, total resistance is the sum of the individual resistances. For resistors in parallel, the reciprocal of total resistance is the sum of the reciprocals. These rules must be applied step by step in combination circuits; draw the reduced equivalent circuit after each step.

串联电阻的总电阻为各电阻之和；并联电阻总电阻的倒数为各电阻倒数之和。在组合电路中必须逐步应用这些规则，每化简一步就画出等效电路。

R_s = R₁ + R₂ + R₃

1/R_p = 1/R₁ + 1/R₂

Resistivity is a property of the material, independent of the shape of the conductor. The resistance of a wire is R = ρL/A, where ρ is resistivity, L is length and A is cross-sectional area. Metals have higher resistivity as temperature increases; a thermistor has lower resistivity as temperature increases.

电阻率是材料本身的属性，与导体的形状
