Lecture Notes

• Lecture 3, Oct 9: Air resistance, Non-linear oscillator

• Lecture 2, Oct 7: Newton’s laws, air resistance

  • Change: the textbook → various books, at the end of page 2.—6:38PM, Oct 06, 2014

• Lecture 1, Oct 2: Intro: particles, dimensions, vectors, scalars, matrices…

  • Addition, change: A new footnote (3). $L \rightarrow O$ in line 2 of page 7.—12:52PM, Oct 02, 2014

  • Correction: Pages 6,7, in definition boxes of vector, scalar: linear → orthogonal.—9:38AM, Oct 02, 2014

Appendices

• A1: Perturbation

  • Correction At the end, the case when $v_0$ is non-zero was discussed incorrectly in the Oct 3 version. Now, corrected.—9:25AM, Oct 05, 2014
