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 ...

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 ...

Have you ever sat down and thought “I wonder if a trebuchet could launch a projectile at supersonic speeds?” Neither have we. That’s what separates [David Eade] from the rest of us. He didn’t just ask ...

The Office of Naval Research is getting ready to deploy their electromagnetic Railgun for testing for the first time next year. But what is a gun without ammo? The Hyper Velocity Projectile is being ...

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 ...

Projectile vomiting is a type of severe vomiting in which stomach contents can be forcefully propelled several feet away from you. It usually comes in shorter, more violent bursts than other types of ...

The projectile is fired using an electromagnetic design similar to a railgun, at insane speeds around 6.5 km/sec (23,400 km/h, 14,540 mph), or just under 19 times the speed of sound. It's aimed ...
