Chapter 3: Relativistic Mechanics
In introductory physics, we often begin with kinematics and then use those concepts in Newtonian mechanics. We will do something similar here. Now that we understand special relativity and its implications for space and time, we need to examine its implications for mechanics particularly for relativistic momentum and energy. We will also explore measurements of the wavelength and/or frequency of light produced by moving sources (the relativistic Doppler effect).
