Simple Harmonic Motion
======================

This chapter covers oscillatory motion, such as springs and pendulums.

Key Concepts:
-------------
- Period and frequency
- Springs (Hooke's Law)
- Pendulums

Sample Question:
----------------
A mass on a spring oscillates with a period of 2 s. What is its frequency?

.. math::
   f = \frac{1}{T} = \frac{1}{2} = 0.5\ \text{Hz}
