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 ...

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 ...

In this video, we introduce the fundamentals of kinematics in 2D, focusing on projectile motion. Learn how to break down the horizontal and vertical components of motion, apply key equations, and ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Anyone who's ever taken a physics course has learned the same myth for ...

A boy kicks a ball horizontally over the edge of a cliff with a speed of \(6ms^{-1}\) as shown in the diagram. The ball hits the surface of the water \(3s\) later. (a) Calculate the vertical speed of ...

WE are told in the Preface to this work that “the consideration of the motion of a projectile naturally divides itself into three parts—first, its motion in the bore of the gun; second, its motion ...

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 ...
