I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...

Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

A boy kicks a ball horizontally over the edge of a cliff with a speed of \(6ms^{-1}\) as shown in the diagram. The ball hits the surface of the water \(3s\) later. (a) Calculate the vertical speed of ...

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 ...
