Speed-time graphs are very useful when describing the movement of an object. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the ...

Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. The object may change direction, eg from forward to backwards, up or down, left or right.

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 ...
