What makes an ability go further?(enemy displacment further)

mainly the poppy E, Vayne E, Syndra QE/QWE.

poppy and vayne E seems to not always knock back the target the same distance shown with the arrow indicator when casting the ability so the enemy doesn't hit a wall and not get stuned.

and the Syndra balls sometimes doesn't travel the full distance, why is that?

those are the three abilities that i remember for now.
