Projectile trajectory around a planet, compared to the motion in a uniform gravity field. When a projectile travels a range that is significant compared to the Earth's radius (above ≈100 km), the curvature of the Earth and the non-uniform Earth's gravity have to be considered.
A spitzer bullet (from German: Spitzgeschoss, "point shot") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
In projectile motion the most important force applied to the ‘projectile’ is the propelling force, in this case the propelling forces are the muscles that act upon the ball to make it move, and the stronger the force applied, the more propelling force, which means the projectile (the ball) will travel farther. See pitching, bowling.
Examples of various small-arms flechettes (scale in inches) A flechette or flèchette (/ f l eɪ ˈ ʃ ɛ t / fle-SHET) is a pointed, fin-stabilized steel projectile.The name comes from French flèchette (from \flèche), meaning "little arrow" or "dart", and sometimes retains the grave accent in English: flèchette.
A Folsom projectile point. Folsom points are projectile points associated with the Folsom tradition of North America.The style of tool-making was named after the Folsom site located in Folsom, New Mexico, where the first sample was found in 1908 by George McJunkin within the bone structure of an extinct bison, Bison antiquus, an animal hunted by the Folsom people.

M712 Copperhead approaches an old M47 Patton tank used as a target M712 detonating. The M712 Copperhead is a 155 mm caliber cannon-launched guided projectile.It is a fin-stabilized, terminally laser guided, explosive shell intended to engage hard point targets such as tanks, self-propelled howitzers or other high-value targets.
Projectile points come in an amazing variety of shapes and styles, which vary according to chronological periods, cultural identities, and intended functions. Typological studies of projectile points have become more elaborate through the years. For instance, Gregory Perino began his categorical study of projectile point typology in the late ...
Generally speaking, a projectile with greater volume faces greater air resistance, reducing the range of the projectile. (And see Trajectory of a projectile .) Air resistance drag can be modified by the projectile shape: a tall and wide, but short projectile will face greater air resistance than a low and narrow, but long, projectile of the ...
