Physics can feel inscrutable to students; this lesson helps them understand a graphing problem by analyzing their own ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

In my mind, however, one item that has to be on the list is calculus. The primary reason engineering and science have progressed rapidly is our ability to model natural phenomena using mathematical ...
