'Ghosting' the bouncing ball

This post focuses on the uselful aspects of 'Ghosting' an animated object. This is when every frame in the objects animation can be seen through wireframe to show the movement of the object between each frame. This was useful for the task of animating these balls because it allowed me to view each frame and make adjustments accordingly. For example, if i wanted the ball's movement to be fast then i would want the balls key frame movement to be very clode to each other to show that less time has passed between each frame. This is the oposite for if i wanted the balls to have slow movement.
 Below is a screen shot capturing the tennis ball being 'Ghosting' from a side view perspective.
