Things to Note:

• All examples in this Illumination have constant acceleration (which may be zero), so the average velocity between two times is simply halfway between the instantaneous velocities at the two times.
• The spacing between tracks of a motion diagram represents the magnitude of the displacement of the object, and thus is found by multiplying the average velocity by the time interval.
• The larger the average speed (magnitude of the average velocity), the larger the displacement over the same time interval.
