Position, Distance & Displacement
The position of an object or a point in space is determined by its distance or direction from other points. This position is always accompanied by a scale of preference or origin using Cartesian coordinates (x, y).
To locate a point
Drawing the (x – y) axis using Cartesian coordinates with suitable scales, the vertical axis is calibrated using a scale e.g. 1cm to 1unit, and the horizontal axis also calibrated using 1cm to 1unit.
By tracing the points and values (2, 3), where the two lines meet represent the position of Q while (4,5) represent P where the two lines meet.
Distance is the amount of space between two points. It is always measured in metres (m) or kilometres. It is a scalar quantity and can be measured using metre rule or tape rule for a larger distance.
Displacement is the distance travelled or covered in a specific direction e.g. A body travelled 5km due North. The distance covered by the body is 5km but in the North direction which shows that displacement is a vector quantity i.e., it has both magnitude and direction. It is measured in metres.
