However, depending on the context, it could be considered part of:
* Kinematics: This branch of physics focuses on the motion of objects without considering the forces that cause the motion. Speed is a fundamental concept in kinematics.
* Dynamics: This branch of physics deals with the forces that cause motion, including acceleration and deceleration, which are directly related to speed.
* Mechanics: This broader field encompasses both kinematics and dynamics, making speed a crucial aspect of understanding how objects move and interact.
So, while there isn't a specific name for "the study of speed," it's a key element within various areas of physics and engineering.
