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 ...

[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 ...

Isaac Newton laid out the physical ballistic requirements to hit the moon with a gun in his famous Cannonball thought experiment. Since Newton, and for years before him, humans have relentlessly ...

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 ...

Ballistic data is the foundation for repeatable accuracy, no matter if you’re a hobby hand loader, archery nut, precision rifle shooter, or long-range hunter. Whether you’re selecting the perfect ...
