Motion of an object in a straight line is known one dimensional motion. The location of a particle in one dimensional motion can be defined by only one variable (say x). For a particle rolling along a straight line (1-D motion) all the vector quantities such as velocity, position, acceleration and displacement have only one non-zero element.
