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 ...

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 ...

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 ...

The terms projectile and trajectory are introduced. Projectile Motion: The terms projectile and trajectory are introduced. Students learn to describe horizontal and vertical components of a projectile ...

Archery and target shooting with firearms and air guns are just a few of the many sports and pastimes that involve high-speed projectiles. A handy accessory for any of these activities is some means ...

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 ...
