GCSE Edexcel Using and interpreting graphs - Edexcel Speed-time and velocity-time graphs - Higher Using graphs is not just about reading off values. In real-life contexts, the intercept, gradient ...

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

During the game, Sportsnet showed the above graph explaining the decrease in velocity of Dickey’s knuckleball this season.

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 ...
