空气阻力
Air resistance
摘要：
大多数入门物理教科书要求学生忽略空气阻力，但没有分析这种近似的适当性。实际上，这种近似在许多教科书问题中是不适当的。这份简短的补充讲义，适合专业和非专业的学生，旨在弥补这一普遍的缺陷（另见arXiv：physics/0412107）。
英文摘要：
Most introductory physics textbooks ask students to ignore air resistance but include no analysis of the appropriateness of that approximation. Indeed the approximation is inappropriate in many textbook problems. This short supplementary handout, appropriate for majors and non-majors alike, is designed to make up for this pervasive shortcoming (see also arXiv:physics/0412107).
