Learn the difference between distance, displacement, speed and velocity, and how to calculate distance, speed and acceleration.

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

How do you turn a bunch of data into a super-handy graph? Keep on reading to learn the final 2 steps in Math Dude's easy 4-step method for making graphs ...

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 ...
