1. Why Mind Maps Work for Physics | 为什么思维导图适合物理复习

Mind maps mirror the brain’s natural way of linking information. In physics, concepts are highly interconnected: a force causes acceleration, which changes kinetic energy, which relates to work done. Drawing a central theme and branching out to forces, energy, motion, and equations creates a powerful recall network. Colours and images strengthen memory, while abbreviated keywords keep the map uncluttered.

思维导图反映了大脑自然地连接信息的方式。在物理中，概念高度相互关联：力产生加速度，加速度改变动能，动能又与做功相关。绘制一个中心主题，并分支出力、能量、运动及方程式，构建起强大的记忆网络。颜色和图像能增强记忆，而缩略关键词则保持导图简洁。

2. Forces and Motion Mind Map | 力与运动思维导图

Start with ‘Forces and Motion’ at the centre. Branch out to scalars and vectors, Newton’s laws, and motion graphs. Under scalars and vectors, add speed/velocity, distance/displacement, mass/weight.

Add a branch for terminal velocity and stopping distance.

以“力与运动”为中心。分支出标量与矢量、牛顿定律和运动图像。在标量与矢量下，添加速率/速度、路程/位移、质量/重量。针对牛顿定律，绘制：第一定律（惯性）、第二定律（F = ma）、第三定律（作用力与反作用力）。包含运动学公式：v = u + at、s = ½(u+v)t、s = ut + ½at²、v² = u² + 2as。再添加一个分支用于终极速度和制动距离。

12. Building Your Own Mind Map Routine | 构建你自己的思维导图习惯

Select a blank A3 sheet or a digital tool. Write the chapter name in the centre. Add 4–6 thick main branches for the biggest subtopics. From each, radiate finer branches with keywords, equations, and tiny diagrams. Use no more than three words per branch line. Review the map before each study session and try to reproduce it from memory. Adapt these sample maps to your own style—adding mnemonics, drawings, or real‑life links. Done consistently, this method turns a huge syllabus into manageable visual chunks.

选择一张空白 A3 纸或数字工具。在中心写下章节名称。添加 4–6 条粗主线，代表最大的子主题。从每一支辐射出更细的分支，写上关键词、公式和小示意图。每条分支线上不超过三个词。每次学习前复习导图，并尝试凭记忆重现。将这些示例导图调整为适合自己的风格——加入助记符、图画或生活联系。持之以恒，这种方法能将庞大的教学大纲变成易于管理的视觉块。
