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.
Projectile motion is a form of motion experienced by an object or particle ... This is, for example, the case with spacecrafts and intercontinental missiles.
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 entries are grouped according to their uses, with rough classes set aside for very similar weapons. Some weapons may fit more than one category (e.g. the spear may be used either as a polearm or as a projectile), and the earliest gunpowder weapons which fit within the period are also included.
A solid spherical projectile made, in early times, from dressed stone but, by the 17th century, from iron. The most accurate projectile that could be fired by a smooth-bore cannon, used to batter the wooden hulls of opposing ships, forts, or fixed emplacements, and as a long-range anti-personnel weapon. Chain shot or Split shot
One example of solid projectile use among mammals is the California ground squirrel, which is known to distract predators such as the rattlesnake and gopher snake from locating their nest burrows by kicking sand into their eyes. [13] A wild female African elephant has also been observed to throw various materials at an interfering rhino. [14]
A familiar example of a trajectory is the path of a projectile, such as a thrown ball or rock. In a significantly simplified model, the object moves only under the influence of a uniform gravitational force field. This can be a good approximation for a rock that is thrown for short distances, for example at the surface of the Moon.
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.
