Answer:

A valid way to construct a motion diagram is to take a series of photographs of a moving object at equal time intervals of time, perpendicular to the direction of motion and overlaying the images to observe the position change with time.

Explanation:

In order to develop a motion diagram, a coordinate system, a zero and appropriate scale should be chosen. Generally positions to the right of the origin are considered positive. Velocity can be determined from the motion diagram by plotting velocity vectors.

The acceleration of an object can also be calculated from the motion diagram.
