In a previous post, I was trying to show that the range of a projectile depends on the launch angle. Yes, this isn't that too difficult to see in an introductory physics course, but how do you show ...

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 ...

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’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 ...

Artillery is getting a speed boost at the US Army Dugway Proving Ground in Utah, where General Atomics Electromagnetic Systems (GA-EMS) test fired a hypersonic projectile multiple times using the ...

The Los Angeles Police Department has lifted a week-old moratorium on the use of certain hard-foam projectiles at protests after a federal judge revised her recent court order restricting the weapons’ ...

The USS Zumwalt (DDG-1000) is the US Navy’s latest warship, commissioned just last month—and it comes with the biggest guns the Navy has deployed since the twilight of the battleships. But it turns ...

opened a new load, assemble and pack facility for 155 mm high explosive artillery projectiles on April 22 in Camden, Arkansas, reinforcing the Army’s strategic effort to expand production capacity, ...
