Position v Time Graphs

Any changes in an object's position over time can be graphed with position on the y-axis and time on the x-axis.

​

​Position vs time graph

​

The slope of a position vs time graph for an object experiencing constant motion is linear (a straight line).

Describing the Motion

Object is moving in a positive direction ​away from the origin with a constant positive velocity.
