Ballistic coefficient is a term used in the field of ballistics, which refers to the ability of a projectile to maintain its velocity and trajectory over a given range. It is an important concept in the design of bullets, missiles, and other projectiles, as it determines how well they will perform in flight and how accurately they will hit their targets.
Definitions
Ballistic coefficient is defined as the ratio of a projectile’s sectional density to its coefficient of form, which is a measure of its aerodynamic shape. In simpler terms, it is a measure of how well a bullet or other projectile will overcome air resistance and maintain its velocity and trajectory over distance.
Origin
The concept of ballistic coefficient was first introduced in the early 20th century by American physicist and ballistics expert Arthur J. Mitchell. Mitchell recognized the importance of aerodynamics in the performance of projectiles and developed the concept of ballistic coefficient as a way to measure and compare their performance.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, ballistic coefficient is defined as “a measure of the ability of a projectile to maintain its velocity and trajectory over a given range, determined by the ratio of its sectional density to its coefficient of form.”
The Oxford English Dictionary defines it as “the ratio of the sectional density of a bullet or other projectile to its coefficient of form, used as a measure of its aerodynamic efficiency.”
Associations
Ballistic coefficient is closely associated with the design and performance of bullets and other projectiles. It is used by ballistics experts and firearms manufacturers to optimize the performance of their products and ensure accuracy and consistency over distance.
Synonyms
Some synonyms of ballistic coefficient include aerodynamic coefficient, drag coefficient, and sectional density.
Antonyms
There are no direct antonyms of ballistic coefficient, but it can be contrasted with other measures of projectile performance, such as muzzle velocity and energy.
The same root words
The root words of ballistic coefficient are “ballistic,” which refers to the science of projectiles in flight, and “coefficient,” which is a mathematical term used to describe a ratio or factor.
Example Sentences
- The ballistic coefficient of this bullet is higher than that of its competitors, making it more accurate over longer distances.
- The aerodynamic design of this missile gives it a high ballistic coefficient, allowing it to maintain its velocity and trajectory even in adverse weather conditions.
- The sectional density of this bullet is lower than its coefficient of form, resulting in a low ballistic coefficient and poor performance at long ranges.
