Do objects that are travelling at a constant velocity not have force since they are indistinguishable from still objects?

Why would they not have force ?

Huh? Forces only exist between two objects interacting. Are you asking if objects, traveling at constant velocity near each other have a force on them? The answer is yes. Obviously.

"have force" and "having force" isnt a statement that makes sense

it might have two forces that cancel out eachother, like gravity and the ground pushing up, to two equal thrusters that face opposite directions

Force is interactive and relative.
"Stillness" doesn't exist in nature. That's an emergent feature of defining a system.

That's called "frame of reference". It's when you arbitrarily define the zero point of a system based on the object you're observing.

Still? Still relative to what? You can't describe something's motion without a frame of reference

No force --> No acceleration

That's the basic rule. Motion has nothing to do with force. Also, since the universe is expanding, there is no still objects in an "absolute" frame of reference.

Not true. Single particle bodies have inertial force from changes in acceleration.
