📚 Mastering the IB Physics Formula Booklet 2025 with Revision Village | 借助 Revision Village 攻克 2025 IB 物理公式手册
The IB Physics data booklet is often seen as a simple reference, but in the 2025 examination it is a strategic tool. Knowing exactly which equations are provided, and more importantly how to apply them, can save time and reduce errors. This article explains how to build formula fluency using the 2025 IB Physics Formula Booklet alongside Revision Village practice.
IB 物理数据手册常被当作一份简单的参考资料，但在 2025 年考试中它是一个策略性工具。准确掌握手册提供了哪些方程，以及更重要的是如何应用它们，可以节省时间并减少失误。本文将说明如何结合 Revision Village 练习，利用 2025 IB 物理公式手册建立公式熟练度。
1. Why the 2025 Formula Booklet Matters | 为什么 2025 公式手册如此重要
In IB Physics, the formula booklet is available for Paper 1 and Paper 2, so you are not expected to memorise every equation. However, a data booklet only helps if you can locate the correct formula quickly and know what each symbol means. The 2025 version is organised by topic areas and includes key constants, making it an essential examination aid.
在 IB 物理中，Paper 1 和 Paper 2 均提供公式手册，因此不要求记住每一个方程。但数据手册只有在你能快速找到正确公式并理解每个符号含义时才有帮助。2025 版按主题区域编排，并包含关键常数，因此是必不可少的考试辅助工具。
Examiners often design questions that require selecting the right equation from a list, rearranging it, and pairing it with a graph or data. Students who treat the booklet as a passive reference tend to lose time. Those who practise with it develop an automatic sense of where each equation lives.
考官常设计需要从列表中选择正确方程、进行移项并配合图像或数据的题目。把手册当作被动参考资料的学生往往浪费时间。那些通过练习熟悉手册的学生能形成对每个方程位置的自动反应。
2. What Has Changed in the 2025 Physics Guide | 2025 物理课程指南有哪些变化
The 2025 Physics course, first examined in 2025, has a revised structure with three organising themes: concepts, skills, and contexts. The formula booklet has been updated to reflect the new syllabus. Some equations have been moved between SL and HL, and a few older equations have been removed or replaced by clearer forms.
2025 年首次考试的物理课程采用了修订后的结构，包含三个组织主题：概念、技能和情境。公式手册已根据新大纲更新。一些方程在 SL 和 HL 之间移动，少量旧方程被删除或替换为更清晰的形式。
It is important to use the 2025 booklet, not a PDF from an old syllabus. Mixing versions can cause you to rely on a formula that is no longer listed or miss a newly included equation. Revision Village resources are aligned to the 2025 guide, which makes cross-checking easier.
使用 2025 版手册而非旧大纲的 PDF 非常重要。混淆版本可能导致依赖已不再列出的公式或漏掉新增方程。Revision Village 资源与 2025 指南一致，便于相互核对。
3. Structure of the IB Physics Formula Booklet | IB 物理公式手册的结构
The booklet groups equations into familiar areas such as mechanics, energy, circular motion, fields, electricity, waves, thermal physics, quantum physics, and nuclear physics. It also includes a page of fundamental constants and mathematical conventions, such as unit prefixes and trigonometric relationships.
手册将方程分组为熟悉的领域，例如力学、能量、圆周运动、场、电、波、热物理、量子物理和核物理。它还包括一页基本常数和数学约定，例如单位前缀和三角关系。
Each section has a compact set of equations, often with definitions of variables in a side column. Some equations are given in multiple equivalent forms, so you must choose the version that best matches the information in the question.
每个部分都有一组紧凑的方程，通常在侧栏中给出变量定义。一些方程以多种等价形式给出，因此你必须选择与题目信息最匹配的版本。
| Symbol | Meaning | Symbol | Meaning |
| F | force | Q | charge |
| v | velocity | λ | wavelength |
| I | current | h | Planck constant |
4. How to Use the Data Booklet in the Exam | 如何在考试中使用数据手册
Before attempting a calculation, write down the given quantities with their symbols, identify the unknown, and then scan the relevant section of the booklet. This prevents you from jumping to a familiar-looking formula that may not fit the data.
在开始计算前，先列出已知量及其符号，确定未知量，然后浏览手册的相关部分。这可以防止你跳到一个看起来熟悉但并不适合数据的公式。
, you will waste time searching. Make quick annotations in your own revision notes such as "for maximum height use v² = u² + 2as".
每次作业和模拟考试都要使用手册练习。如果你只在最终考试中才打开它，你会浪费查找时间。在自己的复习笔记中做快速标注，例如“求最大高度用 v² = u² + 2as”。
5. Key Mechanics and Dynamics Formulas | 力学与动力学重点公式
The mechanics section includes equations of motion for constant acceleration. These are provided, but you must know when acceleration is constant and which sign convention applies.
力学部分包含匀加速运动方程。手册中给出这些公式，但你必须知道何时加速度恒定以及使用哪种正负号规定。
v = u + at
s = ut + ½at²
v² = u² + 2as
Newton' am: resolve all forces, find the net force, and then use F = ma to calculate acceleration.
牛顿第二定律以 F = ma 的形式出现。
