We have had different experiences I guess. Because of all the problems I’ve seen students have, confusion over being pushed has never been one of them. You can avoid that language to preclude misunderstanding if you wish, I don’t see it as a problem. Bottom line is that a push is responsible for the momentum. The same way that a 100mph fastball hurts the catchers hand because the pitcher threw it. I see your point and don’t really disagree. But the areas where it may cause confusion are minimal based on my experience.
