Title: Research on Velocity and Formula in Bullet Ballistics Chart (2) - Taking Velocity Formula 2.0 as an Example Introduction: With people's love for shooting sports and the continuous development of military science and technology, bullet ballistics has gradually attracted people's attention as a discipline that studies the movement laws and performance of bullets during flight. The flight speed and ballistic curve of the bullet are the key links in the research. In this article, we will introduce the formula for velocity in bullet ballistics, "Velocity Formula 20", and how to analyze the velocity and ballistic performance of a bullet through a related graph. At the same time, through the simple way, readers can have a deeper understanding of bullet ballistics. 1. The relationship between bullet velocity and ballistic curve The velocity of a bullet refers to the distance that a bullet travels per unit of time after it is fired. Speed is one of the important factors affecting the ballistic performance of a bullet. In general, the higher the initial velocity of a bullet, the corresponding increase in its range in air. Therefore, the law of velocity change on the ballistic curve of the bullet is one of the key points of research. At the same time, the speed of the bullet is also affected by air resistance and gravity, and gradually decreases with the increase of flight time. Therefore, we need to study the relationship between the flight speed of the bullet and the ballistic curve in order to better grasp the law of bullet motion. 2. Introduction and application of velocity formula 2.0 Velocity Formula 2.0 is a physics-based mathematical formula used to calculate the flight speed and trajectory of a bullet. This formula covers the effects of a variety of factors such as air resistance, gravitational acceleration, and initial launch velocity on the flight of a bullet. Its mathematical form is as follows: V = VoRe^-kt (where V is the flight speed at the current moment, Vo is the initial launch velocity, Re is the constant coefficient, k is the drag coefficient, and t is the flight time). With this formula, we can calculate the flight speed of the bullet at different points in time based on parameters such as known initial velocity and air resistance coefficient. In addition, relevant graphs can be made based on this formula to visually analyze the velocity changes and ballistic properties of the bullet. In practical application, velocity formula 2.0 can determine the parameter values through experimental data, so as to obtain more accurate calculation results. At the same time, the formula can also be used to guide work on shooting training, weapon design, etc. However, it should be noted that the accuracy of the data source should be ensured in practical applications. This is because if there is a large difference between the initial accuracy and the change in the shooting environment, it will affect the result. Therefore, these factors should be fully considered in practical application to ensure the accuracy of the results. In addition, it should be noted that different types of bullets will have different parameters such as drag coefficient and constant coefficient, so when using the velocity formula, it is necessary to select and adjust according to the specific bullet type to ensure the accuracy of the calculation results. 3. Application of Chart Analysis in Bullet BallisticsIn addition to the velocity formula, chart analysis is also one of the important research methods in bullet ballistics. By plotting the trajectory of the bullet, the velocity curve and other charts, the ballistic performance of the bullet can be visually displayed, and help researchers better understand and analyze the movement of the bullet. For example, by comparing the ballistic curves of different types of bullets, it is possible to evaluate their range, penetration and other performance, so as to provide a basis for shooting training and weapon design. In addition, the results of the velocity formula can be verified by chart analysis to ensure the accuracy and reliability of the study. 4. Conclusion: This paper introduces and analyzes the velocity and formula in bullet ballistics, especially the velocity formula, and demonstrates its application value in the research by means of graph analysis. Through the introduction of this paper, readers can have a deeper understanding of bullet ballistics, and learn how to use the method of velocity formula and chart analysis to study the movement law and performance of bullets, so as to provide useful reference and help for the development of shooting sports, military science and technology and other fields.
