Dynamics
========

Dynamics is the study of the forces and their effect on motion.

Key Concepts:
-------------
- Newton's Laws of Motion
- Free-body diagrams
- Friction, tension, and normal forces

Sample Question:
----------------
A 3 kg box is pulled with a force of 15 N. What is its acceleration?

.. math::
   a = \frac{F}{m} = \frac{15}{3} = 5\ \text{m/s}^2
