The first line in the picture shows a constant velocity that the dots are going in. The velocity is the same for each dot. The second line shows the dots with a different amount of space in between them. That is showing the that the dots accelerate at differnet amount after every dot. The shorter the space in betweeb the dots the lower thr acceleration.
