About the 物理基础 certification
本基础级认证将经典物理学的核心概念转化为清晰、实用的工具体系。你将学习测量的语言——国际单位制（SI）、单位前缀与量纲分析——以及标量与矢量的关键区别。在此基础上，你将构建完整的运动学图景：位移、速度与加速度、运动方程、自由落体、抛体运动基础，以及如何解读运动图像。你将掌握牛顿三定律和日常力学——重力、法向力、摩擦力和张力——并学会绘制能真正解决问题的受力分析图。能量章节涵盖功、动能与势能、能量守恒和功率；动量章节涵盖冲量与碰撞。你还将接触圆周运动、万有引力和简单机械，以及日常物理世界的内容——密度、压强与流体、温度与热量、波与声音、光与光学（反射与折射），以及电学基础（电荷、电流、电压、电阻、欧姆定律与简单电路）和磁学。全程强调用正确的单位求解实际问题，而非死记公式。每个概念均有图解，每个公式均通过数字例题加以推导。本认证是进阶任何助理级物理或工程科学认证的自然起点。
What you will learn
The official 物理基础 study course covers:
- Measurement, Units, and Vectors — SI units and prefixes, dimensional analysis, and the all-important difference between scalars and vectors — the language every later topic is written…
- Kinematics: Describing Motion — Displacement, velocity, acceleration, the equations of motion, free fall and projectiles, and how to read motion graphs.
- Forces and Newton's Laws — Newton's three laws, the everyday forces (weight, normal, friction, tension), and how to draw free-body diagrams that solve problems.
- Energy, Work, Momentum, and Power — Work and energy, kinetic and potential energy, the conservation of energy, power, and momentum with impulse and collisions.
- The Everyday Physical World — Density, pressure and fluids; temperature and heat; waves, sound, light and optics; and the essentials of electricity and magnetism.
- 动手实验——模拟运动与能量 — Google Colab 中的物理基础顶点项目：处理单位与向量，模拟抛体运动，应用牛顿定律计算加速度，验证能量和动量守恒。纯 Python 与 numpy 和 matplotlib，免费运行。
Frequently asked questions
- Is the 物理基础 certificate verifiable?
- Yes. Every issued Hootix Academy certificate carries a unique credential code that anyone can verify online.
- How is the 物理基础 exam structured?
- It is a 90-minute ID-verified multiple-choice exam of 60 questions; you need 70% to pass.
- Do I need to buy the course to take the exam?
- Each certification is sold three ways: the exam on its own, the online course on its own, or both together as a Course + exam bundle (the bundle price is the course price plus the exam price).
- How long does the 物理基础 course take?
- About 18 hours of self-paced study.
