EaseIn EaseOut at the top of an arch?

[Streetwise]

I hope I can explain this well enough. I've created a basic event that emits particles straight up, that then start to fall. The problem is when the particles get to the top of the arc, there doesn't seem to be a nice transition in speed before gravity takes over. They just start falling rather abruptly. Is there an adjustment to control this sort of thing?  

Thanks!

Try adjusting the default PhysX gravity strength in the PhysX rollout of the tyFlow.
