Answer 1

Explanation:

The motion of a body in a straight line is called one-dimensional motion. The motion of a body in a plane is called two-dimensional motion. The motion of a body in a space is called three-dimensional motion. When only one coordinate of the body changes with time then it is said to be moving one-dimensionally.
