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 ...

Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

As the name suggests, horizontal motion occurs when the object is thrown horizontally, meaning it starts with zero vertical velocity. The only force acting on the object is gravity, causing it to ...

I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...
