Trace motion with distance, speed, and acceleration

x

A clean educational diagram of a horizontal number line labeled “origin 0” with a positive arrow pointing right and a small moving object placed at “+5 km”; show only the origin, positive direction, and position label.

Start with position

To trace motion, first choose a reference point called the origin and a positive direction. Then position is just where the object is compared with that origin, like altitude = 2,000 m or downrange position = +5 km.
