Does Rinterp override a mesh's physics forces?

Hi, I am trying to apply an RInterp to a mesh that has physics activated and is being launched into the air via an Add Impulse node. But it doesn’t seem to be able to meet the target specified in the RInterp node. Is it because it is fighting against the physics or being overriden by it?

Thanks!

Bump, this has to be a simple question…
