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 ...

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 ...

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 ...

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 ...

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 ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

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 ...
