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 really a lab that I have students do, but I am pretty sure they don't read this blog - so it is ok. If they are reading this, hi! We have these projectile cannons that shoot small balls. In ...

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 ...

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 ...

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 Navy, DoD and even the Army are also experimenting with integrating the rail gun hypervelocity projectile with existing weapons platforms such as the Navy’s 5-inch guns or Army Howitzer. Also, the ...
