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 ...

Question 1: Sketch a graph of velocity vs. time and another graph for position vs. time for this same trip. ... The fake force and the gravitational force are the same magnitude, ...

The cart then detects motion over these lines to give position-time data. Again using the quadratic fit I can find the acceleration. In this case it gives a value of 0.1092 m/s 2 .
