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 ...

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 ...

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 ...

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 ...

This is because projectile vomiting is not just throwing up. It involves more force. Sometimes, a child’s vomit, when "released," can go flying across a room. A child who vomits way too much and with ...

Projectile vomiting causes vomit to be forcefully sent out of the body. The causes of projectile vomiting in adults and infants are often different, and treatment varies depending on why it occurs.
