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 surface of the projectile also must be considered: a smooth projectile will face less air resistance than a rough-surfaced one, and irregularities on the surface of a projectile may change its trajectory if they create more drag on one side of the projectile than on the other. However, certain irregularities such as dimples on a golf ball ...
Knowledge of the projectile drop and path has some practical uses to shooters even if it does not describe the actual trajectory of the projectile. For example, if the vertical projectile position over a certain range reach is within the vertical height of the target area the shooter wants to hit, the point of aim does not necessarily need to ...
Officers fired a 40-millimeter projectile and two beanbag rounds at Maccani as he walked toward them while holding what was later revealed to be a plastic fork, according to video of the incident ...
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.
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]
