Brief form of discussion: Definitely!
Verbose form:
Net force is required to change speed or direction of an object's motion.
No net force is required to keep it moving in a straight line at a constant
speed.
Yes, it can. In fact, if it is moving and there is a zero net force, it will continue moving indefinitely, at a constant velocity (Newton's First Law).
no you cannot prove it is at rest since it may be moving at constant velocity. Constant velocity has no acceleration, hence no net force
It will stay at rest.
Inertia guarantees that an object at rest will remain at rest and an object in motion will remain in that same motion, so long as there is no external force acting on that object. Alternately, there could be force acting on it as long as that force adds up to zero.
When an object is at rest, the forces acting upon it are balanced - there are no unbalanced forces.
If the net forces acting on an object amount to zero, that object is at rest.
in equilibrium with a net force of zero
It will stay at rest.
It will stay at rest.
You can't. The net force simply means that the acceleration is zero. It could be at rest, or the object could be moving at a constant velocity.

An object at rest or in motion with no force acting upon it.
stay at rest
in equilibrium with a net force of zero
If the net forces acting on an object amount to zero, that object is at rest.
a force acting on an object at rest causese it to move
It will keep moving with a constant velocity since zero net force means no acceleration. If the object is at rest, it will just stay at rest.
There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.
