What else can I help you with?
What are the condition for an object to stay at rest to keep moving at constant velocity or to move with increasing velocity?
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.
Can an object that move at a constant speed be accelerating?
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.
What are the condition for an object stay at rest keep moving at constant velocity?
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.
Can an object be accelerating if it has constant 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.
What is the velocity if acceleration is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?
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.

Is it correct to assume a motion of constant speed?
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.
Why is no force required to move an object with a constant velocity?
Newton 2nd Law is the answer
Can an object that move at a constant speed be accelerating?
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.
What are the conditions of an object to stay at rest to keep on moving at constant velocity or to move with increasing velocity?
If the sum of all forces on an object is zero, then the object remains in constant velocity. Constant velocity means motion in a straight line at a constant speed. "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. If the sum of the forces is in the same direction as the object's motion, then the object must speed up.
What are the condition for an object stay at rest keep moving at constant velocity?
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.
What is velocity if the net force is 0?
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.
Can an object be accelerating if it has constant 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.
What is the velocity if acceleration is zero?
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 what can you predict?
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.
Can an object traveling at constant velocity have acceleration?
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.
