Motion in One Dimension is among the earliest lessons in Newtons Classical Mechanics. This page first introduces the terms and then shows users how they are applied to different forms of motion in one dimension.Motion is defined as the action or process of moving or changing place or position. In physics, motion is tracked over time. For the concept of motion in one direction, picture a train going along a straight track. The subject of motion in physics is called a, body. The three properties of motion in one direction are: displacement (x), velocity (v), and acceleration (a). All of these three are linked together very closely.Displacement is defined as the distance (x) a one-dimensional object is from a center point, or an origin. Displacement is plotted against time in a curved graph. A body, in motion in one dimension, can only move left and right.Picture a train that travels along a straight track. The origin is a point on that track, and as the body moves, the distance between the body and the origin is its displacement.
