Momentum. If an object has constant velocity, the object will move because it has momentum. Momentum tends to stay the same unless changed by a force.
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction.
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.
An object will remain at rest if the net force acting on it is zero. An object will continue to move at a constant velocity if the net force acting on it is zero and there is no external force to change its velocity.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
Newton 2nd Law is the answer
It depends on your setting. If the net force on an object is zero than the object will move with a constant speed. It will also move with a constant speed (but not velocity!) if a force forces the object to move in a circular motion.

"Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change.

No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
If the net force acting on an object is 0, then the object will move with a constant velocity. This means that the object will neither speed up nor slow down, but continue to move at a consistent speed in a straight line. This is described by Newton's first law of motion.
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
If you know the constant velocity of a moving object, you can predict its position at any future time by multiplying the velocity by the time elapsed. This assumes that the object continues to move at that constant velocity without any external forces acting on it.
