Everything CCEA students need to know about speed-time graphs for GCSE Physics.

Acceleration and velocity Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate.

At the Porsche test track, we learn the difference between speed and velocity.

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 ...
