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 ...

This content can also be viewed on the site it originates from. Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward ...

Projectile motion describes how objects move through the air after being launched, like when a ball is thrown or an arrow fired. After launching, the only force acting on the projectile is gravity ...

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 ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...
