Hint:The motion of a body is defined as the change in the position of the body, whereas a body that remains stationary at its position as time passes is said to be at rest. There are various branches of physics to study the different types of motions. Using the knowledge of the definition of these branches, we can find out the correct answer. Using the knowledge of the definition of these branches, we can find out the correct answer.
Complete answer:
Let us understand each option one by one;
Statics: It is a subpart of mechanics that concerns the study of the body that is at rest or in motion, even when the body is under several forces. The measurement is not important in statistics.
Kinematics: It is a subpart of mechanics that concerns the study of the motion of the body or system (a group of bodies) without considering the cause of motion. Here the measurement of time is important.
Dynamics: It is a subpart of mechanics that concerns the study of the motion of the body or system while considering the cause of motion. Dynamics is concerned with the different forces that cause the motion of the body. Newton gave a lot to dynamics postulating his famous laws of motion.
Modern physics: It is a subpart of physics that is concerned with the scientific beliefs about the basic structure of the material world and behavior of extremely small body or the body traveling close to the speed of light.From these definitions we see that kinematics is the required term.
Hence, option B is the correct answer.
Note:Projectile motion, circular motion, relative motion, etc. come under kinematics whereas force, energy, laws of motion, etc. come under dynamics. The mechanics is a subpart of physics that deals with the different conditions of rest and motion of the material body in the surrounding. The subtopics of the mechanics are statics, kinematic and dynamics.
