 Acceleration is a useful concept in mechanics, because it can help characterize the motion of systems (e.g., constant velocity motion has no acceleration).
-While you can obtain this information by determining the forces acting on the system, it's possible to use observational information (how the position changes) to determine how the system is accelerating without knowing the system's mass or the forces acting on the system. This is incredibly useful for any type of data collection. Any data collected about the motion of a system only records the position of the system as function of time. From the changes in position (displacement), the velocity can be inferred. From the changes in the velocity, the acceleration can be inferred and thus the motion of the system can be characterized and explained.
