visualizin motion

11. The dots on the tape chart shows the motion of an object
with a constant velocity, deceleration, or acceleration.
The interpretation of the motion of an object depends on
the distance between the dots during a specific time
interval. An equal distance between the dots indicates
constant velocity or when an object is moving at a
constant speed, there is no acceleration. A gradual
change of the distance between dots that gets smaller
means the object slows down which indicates that the
object decelerates. If the distance between dots gradually
gets longer, it means the object speeds up or
accelerates.
