zero! If "free space" is free of forces then the force required to maintain a body at constant speed is zero, because a body at constant speed and direction has zero acceleration and whatever the mass m, f=ma and if acceleration a is zero the force is zero.It takes force to change speed or direction. A body moving around in a circle at constant speed is still changing direction and accelerating and requires force, even if the speed is constant. So you could push the body up to 15 miles per hour and then let go and it would take zero force for the body to maintain 15 miles per hour speed. If you whirled the body on a string up to 15 miles per hour and cut the string , the body would take off in the direction tangent to when the string was cut and go in that direction at 15 miles per hour and it would take zero force to maintain that speed.
Newton's 1st Law of Motion states that an object will maintain its speed when there is no net force acting on it. The question refers to free space and constant velocity -- the net force has to be zero. =========================
Yes, an object moving at a constant speed can maintain a constant velocity if it is moving in a straight line without changing its direction. Velocity is a vector quantity that includes both speed and direction, so as long as the direction does not change, the object's velocity will remain constant.
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
No, the velocity of an object in uniform circular motion (UCM) is not constant. While the speed of the object remains constant, the velocity changes continuously in direction due to the centripetal acceleration required to keep the object moving in a circle.
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.

No, an object cannot maintain uniform velocity when its acceleration is non zero. If an object is accelerating, its velocity will be changing over time, so it cannot maintain a constant velocity. Uniform velocity means the speed and direction of the object remains constant.

Newton 2nd Law is the answer
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.
The property is called inertia. Inertia is the tendency of an object to resist changes in its motion. It can keep an object at rest or maintain its constant velocity unless acted upon by an external force.
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 an object's velocity is constant, it will continue to move at the same speed and in the same direction due to Newton's first law of motion. Unless an external force is applied, the object will maintain its state 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.
