In mathematics, a plane refers to an infinite flat surface that extends infinitely in all directions. It can be described using coordinates or equations.
The velocity vector describes the rate and direction at which the particle is moving within the plane.
Normal Vector: A normal vector is perpendicular (at 90-degree angle) to a given surface or plane. It indicates its orientation relative to other vectors.
