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 ...

In part I of this post, I talked about the basics of projectile motion with no air resistance. Also in that post, I showed that (without air resistance) the angle to throw a ball for maximum range is ...

[Luke Wren] just wrote in to tell us about his new science blog called Wren’s Tech — it’s only a few days old, but he’s already got some pretty cool science experiments written up! Like how to ...

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 ...

As the name suggests, horizontal motion occurs when the object is thrown horizontally, meaning it starts with zero vertical velocity. The only force acting on the object is gravity, causing it to ...

PICATINNY ARSENAL, N.J. (Aug. 13, 2012) -- Why would the U.S. Army want to fire a 155 mm projectile into 540 feet of steel catch tubes and then recover the projectile at the other end? The answer is ...

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 ...
