Projectile motion is a good example of 2D motion that is decomposed into two 1D motions. It is a free fall in the y direction and a uniform motion in the x direction. Conceptually, there is really ...

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 ...

The key to projectile motion is to realize that the horizontal and vertical motions are independent of each other (except for the time each motion takes).
