Objects not perpetually moving in Zero G

Hello,

I am rather new to using Unreal Engine, and I am currently working on a project that involves a collection objects within a box (which is simply made up out of 6 intersecting primitive planes) endlessly floating and bouncing around within it around slowly in zero gravity. At this moment I am currently using a blueprint to apply a small force (with acceleration checked) to each of the objects when the game begins, however all of the objects eventually come to a stop not too long after the game begins. I have ensured that gravity, linear dampening, and angular dampening are all set to 0, and I have also tried to loop the application of the randomized forces to my objects however it just looks unnatural. Is there any way to simply keep the objects moving perpetually in a Zero Gravity state, without the need to constantly apply a random force to it? I have also applied a Physics Material to the objects where I set the friction to of the objects to 0 and set the restitution to 1, however they still come to a stop eventually without the constant application of a force.
