Instantaneous velocity refers to the velocity of an object at a specific point in time, such as a car traveling at 88 m/s at t = 3 seconds when its position function is s(t) = 15t^2 - 2t. Average velocity describes an object's overall change in position, like a person walking east with an average velocity of 1.875 m/s after taking 8 seconds to travel 15 meters. Constant velocity occurs when an object has the same speed and direction throughout its motion, such as a bicycle moving at a constant 4 m/s due north for 12 seconds.
