you could also be a moving observer, that perceives an object that isn't being acted on by a relevant force as moving in a curved path.

There are three possible thoughts for this
1. Geodesic - As explained in http://en.wikipedia.org/wiki/Geodesic
2. In absence of all Forces (Including any Dissipative Force) and in absence of any Change of Energy (To Account for Entropy) we can design a theoretical perpetual machine that would enable an object to move a circular path perpetually without any external force.
3. For sub-atomic particles or for stellar and planetary objects , electrostatic and gravitional forces can enable a body to be on circular motion that exactly balances the centripetal force. The same happens within atoms and in the planetory motion.

Most objects in the universe move in curved paths only. And there is no force making them move so. (Gravity is not viewed by many as a force that causes action at distance, but is merely curvature of space caused by mass.)

No...it's one of the elementary laws of physics. If an object is moving on a curved path, something has to be acting on it.

Yes, if it's following a geodesic. A mass will distort space and a particle will follow the curvature of space and will experience no force. A person riding on that particle will have no idea that a curved path was followed even though it was observed by a distant onlooker.

No, at least not in Newtonian physics. A curved path is an acceleration and that is F=ma.

sounds like a trick question, Is it a hazard to go, in any respect, interior the absence of rigidity of a few form or different, curve or no? do no longer over think of it, have a snack and are available lower back to it.

No. An object in mothion will tend to stay in motion (including not changing direction) unless acted upon by an outside force.

F = ma
look up centripetal acceleration
You will realize that in order for there to be an acceleration (centripetal acceleration), there must be a force, from F = ma
