Special Relativity
... • In 1905, Einstein’s first paper on relativity dealt only with inertial reference frames (constant velocity). • 10 years later, he published a more encompassing theory of relativity that considered accelerated motion and it’s connection to gravity. This was a discussion of “general” relativity. • H ...

Circular Motion
... Do you remember the equations of kinematics? There are analogous equations for rotational quantities. You will see them later in the course. This section is somewhat mis-titled. I believe our starting point for circular motion best involves forces (dynamics). Consider an object moving in a straight ...
