National 5 Velocity-time graphs Speed-time graphs Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to ...

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.

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 ...
