Final answer:
The study of the motion of projectiles is known as Ballistics (C), and it examines the trajectory of objects like bullets affected primarily by gravity. This is a key concept in physics and engineering, encompassing kinematics and dynamics.
Step-by-step explanation:
The science or study of the motion of projectiles, such as bullets, shells, or bombs, is known as Ballistics (option C). This area of study is focused on analyzing the trajectory, which is the path that these objects follow under the influence of various forces such as gravity, and in some cases, air resistance. Specifically, projectile motion is a form of motion where an object is thrown or projected into the air, subject only to the acceleration due to gravity, assuming air resistance is negligible.
Understanding projectile motion is essential in fields such as physics and engineering, where this knowledge can be applied to predict the paths of objects like meteors, fireworks, and sports balls. The study of projectile motion falls under the broader categories of kinematics and dynamics, which describe how objects move and the forces that affect this motion, respectively.
