A non-zero net force, also called an unbalanced force, will cause an acceleration. The amount of the acceleration can be calculated by Newton's Second Law.
it is accelerating; force = mass x acceleration
Its motion is undergoing change in the direction of the net force.

No. Mass is a property of the object and doesn't change, no matter where the object goes or what's happening to it. The force of gravity on the object is its "weight" and that can change. It depends on, for example, what planet the object is on.
Since Fnet = ma... and when Fnet > 0then substituting for Fnet with ma you get: ma > 0assuming a non-zero mass, then a > 0.
weight, The weight of an object is the force of gravity acting on it.

The answer to your question is Work. The definition of work is: "When a force acts against resistance to produce motion in a body, the force is said to do work." - The CRC Handbook of Chemistry and Physics... Which means the exertion of a force on an object that produces motion in the direction of the force.

Yes, it is.
weight, The weight of an object is the force of gravity acting on it.
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
Unbalanced forces are forces that produce a nonzero net force, which changes an object's motion. The result of an unbalanced force is acceleration of an object.

The downward force acting on an object in free fall is Gravity.
