Relative velocity

The video explains the concept of relative velocity using real-life examples of trains and cars. It introduces the idea that the perceived speed of an object depends on the observer's frame of reference. The mathematical explanation involves calculating the relative velocity between two moving cars. Special cases are discussed, such as when two objects move with equal velocity or in opposite directions. The video concludes by summarizing the differences in relative velocity when objects move in the same or opposite directions.
