When drawing a force diagram ... physics? In this short series of explainer films, Professor Brian Cox addresses popular misconceptions and talks viewers through the laws of forces, speed and motion.

Crash Course Physics ... is just the force of gravity. Now all we have to do is solve for time, t, and we learn that the ball took 0.452 seconds to hit the ground. Its horizontal motion didn ...

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 ...

This gives us a great opportunity to explore the physics ... force, the force perpendicular to the slide (we call this the normal force), and the frictional force. Here's a diagram that might ...
