A reference frame is a perspective from which an observer measures and describes physical phenomena, crucial for understanding motion and relative velocity. It provides a coordinate system that allows for the specification of the position and time of events, and can be inertial or non-inertial, affecting how laws of physics are applied.

Relative velocity is the velocity of an object as observed from a particular reference frame, which may itself be in motion. It is crucial for understanding motion in systems where multiple objects are moving relative to each other, such as in collisions or celestial mechanics.

A coordinate system is a method used to uniquely determine the position of a point or other geometric element in a space of given dimensions by using ordered numbers called coordinates. These systems are essential in fields like mathematics, physics, and engineering for mapping, navigation, and spatial analysis.

An inertial reference frame is a frame of reference in which a body not subjected to forces moves in a straight line at constant speed, illustrating Newton's first law of motion. It is essential for the formulation of classical mechanics, as the laws of physics take their simplest form in these frames, allowing for consistent and predictable analysis of motion.

Inertial Reference Frame

A non-inertial reference frame is a frame of reference that is accelerating, either linearly or rotationally, relative to an inertial frame. In such frames, fictitious forces, like the Coriolis force or centrifugal force, must be introduced to explain the motion of objects as observed from within the frame.
