Average velocity over a defined time interval is determined by dividing the total displacement (which represents the change in an object's position) by the total time elapsed during that interval. This relationship can be expressed mathematically as:
Average Velocity = (Change in Position) / (Time Taken)
This formula provides an average estimation of how an object's position evolves during a specific time frame. However, it's essential to recognize that this value signifies an average across the entire duration and may not accurately represent the object's instantaneous velocity at any particular point within that time period.
