Velocity vectors refer to arrows that represent both the magnitude (speed) and direction of an object's motion at a specific point in time.
Displacement measures how far out of position an object is compared to its starting point. It takes into account both distance and direction.
Instantaneous velocity represents an object’s speed and direction at any given moment in time.
Average velocity calculates the overall displacement divided by the total time taken for that displacement; it provides information about average speed and direction over a period of time.
