Physics - Relative velocity

Relative velocity refers to the velocity of an object as observed from a particular frame of reference. It is essential in physics to understand how different observers perceive motion, especially when they are in motion relative to each other. Mathematically, it is calculated by vectorially subtracting the velocity of one object from the other. This concept is fundamental in kinematics, helping analyze collisions, projectile motion, and the motion of objects in different frames, ensuring consistency across measurements.
