This article explores practical techniques for extracting maximum value from Insert 1 (Jun22) during your AS Physics assessment.
考试中提供的AS物理Insert 1远不只是一张简单的参考资料。这是一个精心挑选的公式、常数和换算因子的集合，旨在帮助你高效地解答应用题。学会策略性地使用这一资源可以节省时间、减少错误，并在面对陌生情境时增强你的信心。本文将探讨在AS物理评估中从Insert 1 (2022年6月版) 中获取最大价值的实用技巧。
1. Understanding the Insert: Your Essential Toolkit | 理解公式表：你的必备工具箱
Before the exam, become intimately familiar with the layout of Insert 1. It typically groups equations by topic – mechanics, materials, electricity, waves, and quantum phenomena. Knowing where to find a formula instantly prevents frantic searching under time pressure.
在考试前，要非常熟悉Insert 1的布局。它通常按主题将公式分组——力学、材料、电学、波动和量子现象。立刻就能找到公式的位置，可以避免在时间压力下手忙脚乱地搜寻。
The insert also provides key constants such as the acceleration of free fall g = 9.81 m s⁻², the Planck constant h = 6.63 × 10⁻³⁴ J s, and the elementary charge e = 1.60 × 10⁻¹⁹ C. Treat these as correct values that do not require memorisation – but you must know when to apply them.
数据手册还提供了关键常数，如自由落体加速度 g = 9.81 m s⁻²、普朗克常数 h = 6.63 × 10⁻³⁴ J s 以及基本电荷 e = 1.60 × 10⁻¹⁹ C。把这些当作无需记忆的正确数值——但你必须知道何时应用它们。
Always check the units listed beside each quantity in the insert. A speed given in km h⁻¹ in the question must be converted to m s⁻¹ if the formula expects SI units. The insert itself reminds you of the base SI units through its notation.
始终检查数据手册中每个物理量旁边列出的单位。如果题目中给出的速度单位是 km h⁻¹，而公式要求使用国际单位制，则必须将其转换为 m s⁻¹。数据手册本身通过其符号标注提醒了你基本国际单位。
2. Identifying the Relevant Formula | 识别相关公式
Read the problem statement and underline the physical quantities mentioned – displacement, force, potential difference, wavelength, etc. Then scan the insert for equations that connect exactly those quantities. Avoid the common mistake of selecting a formula simply because it contains one familiar symbol.
阅读题目陈述，并在提到的物理量下划线——位移、力、电势差、波长等。然后浏览数据手册，寻找恰好联系这些量的方程。要避免一个常见错误：仅仅因为公式中包含一个熟悉的符号就选择它。
For applied problems, the question often describes a real-world situation. Translate that description into physics language. For example, “the car comes to a stop” implies final velocity v = 0. “A wire stretches by 2 mm” relates to extension ΔL in the Young modulus formula.
对于应用题，题目通常会描述一个真实世界的情境。将这种描述转换成物理语言。例如，“汽车停下来”意味着末速度 v = 0。“一根导线伸长了 2 mm” 涉及杨氏模量公式中的伸长量 ΔL。
Write the chosen formula prominently at the top of your working. This not only organises your solution but also earns method marks even if a numerical slip occurs later.
把你选定的公式醒目地写在解题过程的开头。这不仅能使你的解答有条理，而且即使之后出现数值上的小差错，也能为你赢得方法分。
3. Extracting Data from the Question | 从题目中提取数据
Create a simple data list: symbol = value (unit). Convert all values to SI units before substituting. For instance, 25 cm becomes 0.25 m, and 72 km h⁻¹ becomes 20 m s⁻¹ (since 72 ÷ 3.6 = 20).
创建一个简单的数据列表：符号 = 数值（单位）。代入前将所有数值转换为国际单位。例如，25 cm 变成 0.25 m，72 km h⁻¹ 变成 20 m s⁻¹（因为 72 ÷ 3.6 = 20）。
Some problems embed a quantity inside a phrase. In “the tension in the cable is 1.2 kN”, the force F is 1200 N. Highlight these converted values to avoid accidentally using the raw number.
有些题目会把一个物理量隐含在短语中。在“缆绳中的张力为 1.2 kN”中，力 F 就是 1200 N。高亮标出这些转换后的值，以避免不小心使用了原始数字。
If a question gives more data than needed, do not panic. Identify the target quantity and work backwards through the insert to find a path that uses only the given values.
如果一道题给出的数据多于所需，不要慌张。确定目标物理量，然后反向浏览数据手册，找到一条仅使用给定值的求解路径。
4. Unit Consistency and Conversion | 单位一致性与转换
The insert assumes SI units for most equations unless otherwise stated. For example, the resistivity formula R = ρL/A requires length in metres and area in m². If the question supplies diameter in mm, first calculate the cross‑sectional area A = πd²/4 in m².
除非另有说明，数据手册中的大多数公式都假定使用国际单位。例如，电阻率公式 R = ρL/A 要求长度以米为单位，面积以 m² 为单位。如果题目给出直径的是毫米，首先计算截面积 A = πd²/4，单位是 m²。
Use the relationships printed in the insert: 1 eV = 1.60 × 10⁻¹⁹ J, 1 u = 1.66 × 10⁻²⁷ kg. These conversion factors are there precisely because examiners want you to apply them in energy and nuclear calculations.
使用数据手册中印出的关系式：1 eV = 1.60 × 10⁻¹⁹ J，1 u = 1.66 × 10⁻²⁷ kg。这些换算因子正是考官希望你在能量和核计算中应用的。
Always perform a unit check after obtaining an answer. If you expect a force in newtons, the product of kg and m s⁻² confirms correctness. The insert can serve as a quick reference for derived units like the joule (J = N m = kg m² s⁻²).
得到答案后，务必进行单位检查。如果你预期力的单位是牛顿，那么 kg 与 m s⁻² 的乘积就能确认其正确性。数据手册可以作为焦耳等导出单位（J = N m = kg m² s⁻²）的快速参考资料。
5. Rearranging Equations with Confidence | 自信地进行方程变换
Many applied problems require you to isolate the unknown on one side of the formula. Write the original equation exactly as it appears in the insert, then rearrange algebraically before inserting numbers. This reduces arithmetic mistakes.
许多应用题要求你把未知量移到公式的一边。先完全按照数据手册中的样子写出原始方程，然后在代入数字之前进行代数变换。这可以减少算术错误。
When dealing with quadratic forms like s = ut + ½at², identify which variable is zero. Often initial velocity or displacement simplifies the expression. Do not solve a quadratic unnecessarily if a term vanishes.
在处理像 s = ut + ½at² 这样的二次形式时，要识别出哪个变量为零。初速度或位移常常会使表达式简化。不要在没有必要的情况下求解二次方程，如果某项为零的话就直接化简。
e.g. v² = u² + 2as → s = (v² − u²) / 2a
Practise rearranging equations from every section. Rearrangement of the diffraction grating formula nλ = d sinθ to find sinθ = nλ/d is a typical requirement.
练习变换来自每个部分的方程。将衍射光栅公式 nλ = d sinθ 变换为 sinθ = nλ/d 就是一个典型的考点。
6. Using Constants and Standard Values | 使用常数和标准值
The insert gives you the gravitational constant G = 6.67 × 10⁻¹¹ N m² kg⁻², the Avogadro constant NA = 6.02 × 10²³ mol⁻¹, and the Boltzmann constant k = 1.38 × 10⁻²³ J K⁻¹. These are often needed in calculations where they are not explicitly stated in the question stem.
数据手册给出了引力常数 G = 6.67 × 10⁻¹¹ N m² kg⁻²、阿伏伽德罗常数 NA = 6.02 × 10²³ mol⁻¹ 以及玻尔兹曼常数 k = 1.38 × 10⁻²³ J K⁻¹。这些常数常常需要用在题目题干中并未明确给出的计算中。
When a problem involves the photoelectric effect, you will likely need h and sometimes the work function derived from threshold frequency. Even if the question only supplies a graph, the slope or intercept can be checked against the constant on the insert.
当题目涉及光电效应时，你很可能会用到 h，有时还需要用到由截止频率导出的逸出功。即使题目只提供了一个图像，你也可以用数据手册上的常数来检验斜率或截距。
Memorise the meaning of prefixes like M, k, m, μ, n, p listed in the insert. Converting 5.0 μA to amperes (5.0 × 10⁻⁶ A) is a routine step that must become automatic.
记住数据手册中列出的 M、k、m、μ、n、p 等前缀的含义。将 5.0 μA 转换为安培（5.0 × 10⁻⁶ A）是一个必须变得自动化的常规步骤。
7. Multi-Step Problem Solving | 多步问题求解
Difficult applied questions rarely require just one formula. Break the problem into stages: Stage 1 might use kinematics to find acceleration, Stage 2 applies Newton’s second law to find force, and Stage 3 uses pressure = force/area. Reference the insert at each stage.
高难度的应用题很少只需要一个公式。把问题分解成几个阶段：第一阶段可能用运动学来求加速度，第二阶段用牛顿第二定律来求力，第三阶段用 压强 = 力/面积。在每个阶段都参考数据手册。
Always check if an intermediate result can be reused in a later formula on the insert. For instance, the kinetic energy ½mv² calculated from the mechanics section may appear in the work–energy principle or in electrical power questions.
始终检查一个中间结果是否可以在数据手册的后续公式中再次使用。例如，从力学部分算出的动能 ½mv² 可能会出现在功能原理或电功率的问题中。
Write your solution as a logical chain: Formula A → value X, Formula B → value Y, Goal quantity via Formula C. This makes your reasoning transparent and resilient to partial errors.
把你的解答写成一个逻辑链条：公式 A → 值 X，公式 B → 值 Y，通过公式 C 得到目标量。这会使你的推理过程透明，并且能容忍部分错误。
8. Interpreting Graphs with Insert Data | 结合Insert数据解释图像
Graph questions frequently test the relationship y = mx + c. Identify the physics equation from the insert that matches the graph’s variables. For a voltage–current graph, compare V = IR with y = mx; the gradient gives resistance R.
图像题经常考查关系式 y = mx + c。从数据手册中找出与图像变量相匹配的物理方程。对于电压—电流图像，将 V = IR 与 y = mx 进行比较；其斜率就是电阻 R。
When a graph plots ½mv² against height h, the insert shows Ep = mgh; the slope equals mg. Use the known value of g from the insert to verify the consistency of experimental data.
当一幅图以 ½mv² 对高度 h 作图时，数据手册显示 Ep = mgh；其斜率就等于 mg。利用数据手册中已知的 g 值来验证实验数据的一致性。
If the graph shows an intercept, it often represents a systematic error or an initial condition (e.g. u² in v² = u² + 2as). Use the insert to justify what the intercept physically means.
如果图像显示出截距，它通常代表系统误差或初始条件（例如 v² = u² + 2as 中的 u²）。用数据手册来证明截距在物理上的含义。
9. Approximations and Order-of-Magnitude Checks | 近似与数量级检查
After calculating an answer, quickly estimate the order of magnitude using rounded numbers. If the insert gives the mass of an electron as 9.11 × 10⁻³¹ kg, the mass of a proton as 1.67 × 10⁻²⁷ kg, your answer for the mass of an atom should lie between 10⁻²⁷ and 10⁻²⁵ kg.
计算出答案后，用取整的数字快速估算它的数量级。如果数据手册给出电子的质量为 9.11 × 10⁻³¹ kg，质子的质量为 1.67 × 10⁻²⁷ kg，那么你算出的一个原子的质量就应该在 10⁻²⁷ 到 10⁻²⁵ kg 之间。
Use the fact that the insert contains typical values – such as the density of water (1.0 × 10³ kg m⁻³) – to check whether your answer for buoyancy or pressure makes sense. Unrealistic magnitudes indicate a unit conversion error or a wrong formula choice.
利用数据手册中包含的典型值——例如水的密度（1.0 × 10³ kg m⁻³）——来检查你算出的浮力或压强答案是否合理。不切实际的数量级表明存在单位转换错误或选错了公式。
Quick sanity test: If the calculated speed of a runner is 200 m s⁻¹, re-examine km to m conversion.
快速合理性检验：如果算出的跑步者速度是 200 m s⁻¹，请重新检查千米到米的换算。
10. Common Pitfalls and How to Avoid Them | 常见陷阱与避免方法
Pitfall: Using the wrong mass – electron rest mass me vs. Planck constant h. These symbols look similar when handwritten. Always double-check the symbol’s meaning from the insert’s list of quantities.
陷阱：用错了质量——电子静止质量 me 与普朗克常数 h。手写时这些符号看起来很相似。一定要根据数据手册中的物理量列表反复核对符号的含义。
Pitfall: Forgetting to square the velocity in kinetic energy. The insert clearly shows ½ mv². Underline the exponent while reading the formula.
陷阱：在动能中忘记了将速度平方。数据手册清楚地显示了 ½ mv²。阅读公式时要在指数下面划下划线。
Pitfall: Mixing degrees and radians. The diffraction grating formula nλ = d sinθ requires θ in degrees in AS Physics. However, when using small-angle approximation, be careful. The insert does not supply the small-angle approximation, so stick to direct calculation.
陷阱：混淆了角度制和弧度制。在AS物理中，衍射光栅公式 nλ = d sinθ 要求 θ 以度为单位。然而，在使用小角度近似时要小心。数据手册没有提供小角度近似，所以请坚持直接计算。
Always re-read the question’s requirement for the final unit. A question may ask for the answer in kJ or N cm⁻². Convert only after completing the SI‑based calculation, using the conversion factors from the insert if needed.
始终重读题目对最终单位的要求。题目可能会要求答案以 kJ 或 N cm⁻² 为单位。只有在完成基于国际单位的计算之后再进行转换，如果需要的话可以使用数据手册中的换算因子。
11. Timed Practice with the Insert | 利用数据表进行计时练习
Treat the insert as an integral part of every past-paper session. Place it next to you and avoid writing formulas from memory – simulate the real exam condition where you rely on the booklet. This builds speed in locating equations.
把数据手册当作每次做历年真题时不可或缺的一部分。把它放在你身边，避免凭着记忆写出公式——模拟你依赖这本手册的真实考试情境。这能加快你定位方程的速度。
Create revision cards that link a typical problem opener to the insert page. For example, “A ball is thrown vertically upwards” points to the kinematics section. “A metal wire is loaded” leads to the materials section with the Young modulus equation.
制作一些复习卡片，将典型的题目开场白与数据手册的页码联系起来。例如，“一个球被竖直向上抛出”指向运动学部分。“一根金属丝被施加载荷”则导向包含杨氏模量方程的材料部分。
Use the specification to identify which formulas are given and which you must remember. AS Physics usually provides the more complex equations, such as those for oblique projectile motion, while very basic ones like v = fλ may not appear on the insert. Know the boundaries.
利用考试大纲来确定哪些公式是提供的，哪些是你必须记住的。AS物理通常提供较复杂的方程，比如斜抛运动的公式，而非常基础的公式如 v = fλ 可能不会出现在数据手册上。要清楚这些界限。
12. Final Tips for Exam Success | 考试成功的最后提示
Before the exam, write a short note to yourself on a scrap paper: “Check insert for constants, rearrange first, SI units always.” This mental checklist, combined with the physical insert, dramatically improves accuracy.
在考试前，在一张草稿纸上给自己写一个简短的提示：“从数据手册中核验常数，先做代数变换，始终使用国际单位。”这个心理检查清单与物理数据手册相结合，能显著提高准确性。
If stuck, scan the insert for an equation containing the unknown quantity. That often illuminates a pathway. The Jun22 insert is your silent partner – use it proactively rather than as a last resort.
如果遇到困难，仔细扫描数据手册，寻找包含未知量的方程。这通常能照亮一条解题路径。Jun22版数据手册是你沉默的伙伴——要主动使用它，而不是把它当作最后的救命稻草。
Remember that examiners design applied problems specifically to test your ability to select and manipulate information from the insert. Every symbol and number on those pages has a potential role in your solution. Trust the resource and let it guide your structured approach.
请记住，考官设计应用题是专门为了测试你从数据手册中选择和加工信息的能力。手册页面上每一个符号和数字都可能在你的解答中发挥作用。信任这份资源，让它引领你采用结构化的解题方法。
