Physics - Coordinate system basics

A coordinate system in physics provides a framework to specify positions and describe motion in space. The most common types include Cartesian, polar, and spherical coordinates. Cartesian coordinates use x, y, and z axes to define points with numeric values. Polar coordinates specify points by radius and angle in a plane, while spherical coordinates extend this to three dimensions with radius, inclination, and azimuth. Understanding coordinate systems is fundamental for analyzing forces, trajectories, and physical phenomena accurately.
