Distance-time graphs show how the distance travelled by a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, going back to the ...

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 ...

In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.
