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 ...

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 ...
