Videos tagged with Gravity

This video explores using gravity to potentially increase muzzle velocity in firearms. While the specific firearm and caliber are not detailed in the provided information, the core concept suggests a focus on physics and its application to ballistics. The tag #MCK is a specific identifier that would be highly relevant to the video's original audience. The content likely delves into theoretical or experimental aspects of firearm performance.

This "Daily Defense" episode delves into rifle ballistics, focusing on external ballistics and their impact on AR-15 platforms without complex math or graphs. It explains how gravity, air resistance (affected by temperature, altitude, and humidity), and height over bore influence bullet trajectory. Key concepts like initial intersection, maximum ordinate, and terminal intersection are detailed. The video also touches on terminal ballistics, highlighting how bullet velocity at impact and bullet fragmentation affect wounding capability and lethality in self-defense or hunting scenarios.

This video demonstrates the flight time of arrows shot vertically using different bow types. A recurve bow arrow fell in 8.5 seconds, a compound bow arrow in 12 seconds, and a high-speed crossbow arrow in 18.5 seconds. Specialized whistling arrow tips were used to aid in tracking the arrow's descent, adding weight but providing an auditory cue.

This bonus podcast episode from Tom Gresham's Guntalk archives revisits a column originally published in Guns & Ammo magazine in April 2001. The discussion centers on the principles of projectile trajectory, using gravity as a key example. It also delves into the ongoing political and legal aspects of gun rights, emphasizing that both the influence of gravity on ballistics and the fight for firearm ownership rights remain relevant. The description also provides extensive details on how to access the Guntalk radio show and podcasts through various platforms and apps.
