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

Position-Time Graph (a) for motion with positive acceleration (b) for motion with negative acceleration (c) for motion with zero acceleration Velocity-Time Graph (a) An object is moving in a ...

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

But if you calculate the acceleration without the graph, you are explicitly stating that the y-intercept is zero---which it might not be. So there are some actual reasons for making a graph.

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 ...
