How is average velocity determined?

Average velocity is a key concept in physics, particularly in kinematics, where it describes the overall effect of displacement over a specified time interval. To determine average velocity, you can use the formula that expresses it as the arithmetic mean of the initial velocity (u) and the final velocity (v). In this case, the formula is given by the expression that combines both velocities, showing that the average velocity takes into account the starting and ending points during the motion.

Using the formula, average velocity (V) can be calculated as:

V = (u + v) / 2

This formula is particularly applicable in scenarios where motion occurs with uniform acceleration or deceleration. It provides a simple and intuitive way to calculate the average velocity over a period of time, considering both the initial and final velocities rather than just focusing on one or the other.

Understanding velocity in terms of both its initial and final values allows for a more complete picture of the object's motion, especially in situations where it may not be moving at a constant speed. Other formulas listed may be valid in specific contexts but do not accurately define average velocity in a straightforward manner.
