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.
A projectile is any object projected into space (empty or not) by the exertion of a force. Although any object in motion through space (for example a thrown baseball) is a projectile, the term most commonly refers to a weapon. [8] [9] Mathematical equations of motion are used to analyze projectile trajectory. [citation needed]
The projectile carried 88 M42/M46 grenade-like dual purpose submunitions. The grenades are very similar, but M42 side wall is optimized for fragmentation characteristics while M46s have thicker walls strengthened to withstand additional setback loads in the last three aft layers of the projectile, where they are placed.

155 mm artillery shells containing HD (sulfur mustard) agent at Pueblo chemical weapons storage facility – Note the colour-coding scheme on each shell. Chemical shells contain just a small explosive charge to burst the shell, and a larger quantity of a chemical agent or riot control agent of some kind, in either liquid, gas or powdered form.
An 8-inch US Army field gun in action during the bombardment of Brest.. In 1919, the Westervelt Board described the ideal heavy gun for future development having a bore of 194 mm to 8 inches, a projectile of about 200 lbs in weight, and a range of 35,000 yards.
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 or bullet length also affects limit cycle yaw. Longer projectiles experience more limit cycle yaw than shorter projectiles of the same diameter. Another feature of projectile design that has been identified as having an effect on the unwanted limit cycle yaw motion is the chamfer at the base of the projectile.
Indirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and inclination, and may include correcting aim by observing the fall of shot and calculating new angles.
