What is relative motion?

Relative motion is the movement of an object in relation to another. It can be studied in physics by analyzing the motion of one object with respect to another that is considered stationary or in motion itself.

Relative motion can be described using concepts such as velocity, acceleration, direction, and position relative to an observer or reference point. For example, a person walking on a moving train is undergoing relative motion compared to someone standing on the platform.

In order to analyze relative motion, it is important to consider the frame of reference, which is the coordinate system used to describe the motion of objects. This can be a fixed point in space or a moving object from which the motion of other objects is observed.

Relative motion is commonly encountered in everyday situations, such as driving a car on a highway, flying in an airplane, or walking on a moving sidewalk. Understanding relative motion is important in various fields such as engineering, astronomy, and navigation, as it helps in predicting and controlling the movement of objects in relation to one another.
