How many types of motion are there based on the number of coordinates required to describe the motion of an object

If we are talking about the Cartesian coordinates system where coordinates are represented by  (x,y,z). 

Then depending upon how many coordinates are used to describe the motion of an object, there are 3 types of motion. 

  1.  One Dimension (1-D) Motion-

           If only one coordinate is used to describe the motion of an object.

            \rightarrow Motion along a straight line is an example of  is 1-D motion

               E.g: Train running on a single track, Apple falling from a tree

  1. Two Dimension (2-D)-

           When two coordinates are used to describe the motion of an object.

                         \rightarrow Motion in the plane is an example of  is 2-D motion

                       E.g Earth revolves around the sun.

  1. Three Dimension -

           When all the three coordinates are used to describe the motion of an object.

                       \rightarrow The motion in space is 3-D motion.

                    e.g: object moving in space randomly.
