With the observed acceleration of the universe, does this change the theory?

Newtons 2nd law states that an object in uniform motion stays in uniform motion unless an external force acts on it. The physics of the expansion of the universe, i.e. cosmology requires the use of general relativity. Newtons Law is only applicable at low velocities and in an inertial frame (this is not the case when the curvature of space-time by gravity is being taken into account).

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

if the object is decresing o increasin speed than it has an acceleration, and to answer your question, any object in the universe has a gravitational acceleration and is related to Free fall.
hope it helps ;)

Without force applied, just stay in motion.
