In the context of motion and physics, the terms "initial velocity" and "final velocity" refer to the velocities of an object at different points in time during its motion.
Initial Velocity: The initial velocity, denoted as "u," is the velocity of an object at the beginning or starting point of its motion. It represents the speed and direction of the object when it initiates its movement.
Final Velocity: The final velocity, denoted as "v," is the velocity of an object at the end or final point of its motion. It represents the speed and direction of the object at the conclusion of its movement.
The initial and final velocities are often used in calculations to determine various aspects of motion, such as acceleration, displacement, or time. The difference between the initial and final velocities can provide valuable information about the changes that occur in an object's motion over a given time interval.
