No, initial velocity and constant velocity are not the same.
Initial velocity refers to the velocity of an object at the start of a particular time interval or motion. It represents the speed and direction of an object at the beginning of its motion.
Constant velocity, on the other hand, refers to a situation where an object's velocity remains unchanged over time. In this case, both the magnitude (speed) and direction of the velocity remain constant throughout the entire motion.
So while initial velocity describes the velocity of an object at a specific instant, constant velocity refers to a consistent velocity that does not change.
