Two vectors that lie along the same line-apex
zero-dimensional examples: Endpoints of edges (vertices and corners) Zero-dimensional figures lie in two-dimensional planes. one-dimensional examples: Edges of figures (sides and arcs) One-dimensional figures lie in two-dimensional planes.
two-dimensionalOn a+ the answer is three-dimensional
Lines are one-dimensional objects but they can be in 2-dimensional - or even 20-dimensional) space.
One dimensional is (probably) a line.Two dimensional is a flat plain figure, showing length x width.Three dimensional is a cubic shape, showing length x width x depth.
One-dimensional motion is motion in a straight line.
A motion along straight line is called rectilinear motion. In general, it need not be one - dimensional; it can take place in a two dimensional plane or in three dimensional space. But, it is always possible that rectilinear motion be treated as one dimensional motion, by suitably orienting axes of the coordinate system.
2 dimensional motion
Simple harmonic motion (SHM) is in one dimension whereas oscillatory motion is 2-dimensional motion that is SHM in one dimension but linear in another.Simple harmonic motion (SHM) is in one dimension whereas oscillatory motion is 2-dimensional motion that is SHM in one dimension but linear in another.Simple harmonic motion (SHM) is in one dimension whereas oscillatory motion is 2-dimensional motion that is SHM in one dimension but linear in another.Simple harmonic motion (SHM) is in one dimension whereas oscillatory motion is 2-dimensional motion that is SHM in one dimension but linear in another.

Two vectors that lie along the same line
It helps to think of dimensions as directions of movement. One-dimensional motion, therefore, is motion in a single direction - in other words, just a straight line.
One dimension has only one axis of possibilities. Motion in one dimension is motion on straight line. Two dimensions is motion on a plane. Two axes meet at right angles and extend in both directions. A point can be located anywhere that can be described as two points in this plane.
Basically yes, a staight line has one dimension ie., length. A plane has 2 dimensions, width and length. A cube is an example of a 3 dimensional object, it has width, length and depth.
