"acceleration"
velocity
It can be a force or the absence of a force. A body at rest remains at rest unless it is acted on by a force. But, a body in motion will continue to move at a constant velocity (change its position) unless it is acted by a force.
It moves with uniform acceleration,because it has a constant force acting on it (its weight).
when it is at rest, or in constant uniform motion with net force and moment of zero (no acceleration)
Yes. When an outside force acts upon a body in motion, it will move in the direction of the force. This is inferred from Newton's first law of motion that states that a body at rest remains at rest or a body in motion remains in motion in a straight line at constant velocity, unless acted upon by an outside force.
a body at rest will stay at rest unless acted on by an unbalanced force; also a body in motion at constant velocity will stay in motion at constant velocity unless acted on by an unbalanced force

From a kinematic perspective, whenever an object's velocity changes at a constant rate it is in uniform acceleration.From a dynamic perspective, whenever the net force on an object is constant the object will undergo uniform acceleration.
Not really, Newton's first law of motion is: "Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force. [2][3][4] This means that in the absence of a non-zeronet force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line."
a body remains at rest or in motion with a constant velocity unless acted upon by external force.
Uniform Constant Deceleration
In absence of any external force, the body would oscillate indefinitely with a constant amplitude a, then it is called free oscillation. When a body, being acted by an external periodic force ,oscillates with the frequency of the force, then the oscillation of the body is called forced oscillation.
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
No. "Uniform motion" means motion at a constant speed in a straight line. But the speed of a body falling freely to the ground is continuously increasing, in response to the force of gravity.
