The last time I looked at this projectile motion lab, I was confused. My different methods for measuring the launch speed of the ball were not even close to being consistent. So, I am bringing out the ...

This is a preview. Log in through your library . Abstract We show that a projectile launched horizontally with a drag force dependent on a power of the velocity will reach a minimum velocity before ...

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 ...

Archery and target shooting with firearms and air guns are just a few of the many sports and pastimes that involve high-speed projectiles. Try this measurement technique. Archery and target shooting ...

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 ...

Guided-missile destroyer Lyndon B. Johnson (DDG-1002) is made ready before flooding of the dry dock at General Dynamic-Bath Iron Works shipyard. US Navy Photo ARLINGTON, Va. – The Navy is still ...

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 ...

September 28, 2020: The U.S. Air Force recently tested the 155mm version of its HVP (Hyper Velocity Projectile) fired from an army M-109 self-propelled 155mm howitzer. The HVP hit an incoming target ...

One of the SCO’s priorities was adapting technology from “railguns”. Such guns use neither explosives nor propellant, but instead rely on electromagnetic forces to fire projectiles at speeds of up to ...

The United States Navy reportedly tested an advanced long-range artillery round from a destroyer at last summer’s Rim of the Pacific exercise. Defense officials told USNI News that the USS Dewey fired ...
