📚 AS AQA Physics Unit 1 Insert Jan 19: Key Data & Formulas | AS AQA 物理第一单元 2019年1月插页：关键数据与公式指南

In the AS AQA Physics Unit 1 paper sat in January 2019, candidates were given an ‘insert’ — a data and formulae sheet. This insert is not just a safety net; it is a tool that can save time and prevent errors if you know exactly how to use it. In this article, we will break down the key content of that insert, explain how to apply the equations and constants, and highlight common traps.

在2019年1月的AS AQA物理第一单元考试中，考生会拿到一份“插页”——即数据与公式表。这份插页不仅是安全网，更是一个能帮你节省时间、避免错误的工具，前提是你确切知道如何使用它。在本文中，我们将拆解该插页中的关键内容，解释如何运用其中的方程和常数，并强调常见陷阱。

1. Purpose of the Physics Insert | 物理插页的用途

The insert is provided with every AQA AS Physics paper. Its purpose is to supply the fundamental constants and standard equations that apply to the questions in Unit 1. It is not intended to replace your understanding; rather, it ensures that calculations are fair and that every candidate works from the same data.

插页随每份AQA AS物理试卷提供。其用途是提供适用于第一单元试题的基本常数和标准方程。它并非要取代你的理解；相反，它确保计算公平，且每位考生都使用相同的数据。

On the January 2019 Unit 1 insert, you would find constants such as the Planck constant, the speed of light, and the charge on an electron. These are used repeatedly in quantum and electricity questions.

在2019年1月第一单元插页上，你会找到诸如普朗克常数、光速和电子电荷等常数。它们在量子和电学题目中反复使用。

2. Layout and How to Read the Insert | 插页布局及如何阅读

The insert usually has two blocks. The first lists physical constants with their symbols, values and units. The second contains equations arranged by topic, for example ‘Quantum phenomena’ and ‘Current electricity’.
