The force required to maintain an object at a constant velocity in free space is equal to what?

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.

What is the force required to maintain an object at a constant velocity in free space equal to?
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. =========================
Can object at constant speed can maintain constant velocity?
It can, but it won't always. In other words, if the speed is constant, the velocity may, or may not, be constant as well.
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Can the direction of the velocity of an object change keeping the acceleration constant?
In order to change the direction of the velocity, acceleration is absolutely required. And as long as you've got it, there's no reason why it can't be constant. An object moving in a circle at a constant speed ... like a TV satellite ... has constant acceleration, and the direction of its velocity is constantly changing.
What force would be required to pull a 10.0 kg wooden block at a constant velocity on Jupiter?
Moving at constant velocity doesn't require any force, regardless of the object's mass or where it is.

Can object at constant speed can maintain constant velocity?
It can, but it won't always. In other words, if the speed is constant, the velocity may, or may not, be constant as well.
Why is no force required to move an object with a constant velocity?
Newton 2nd Law is the answer
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Can the direction of the velocity of an object change keeping the acceleration constant?

An object moving in a circle at a constant speed ... like a TV satellite ... has constant acceleration, and the direction of its velocity is constantly changing.
Why is a net force not required for an object to maintain a constant speed?
Newton's 1st Law
Can an object have a constant speed and velocity at the same time?
Yes. An object moving in a straight line at constant speed has constant velocity.
What happens to the velocity of an object even if the speed of an object remains constant?
Velocity can change even if speed is constant.
What force would be required to pull a 10.0 kg wooden block at a constant velocity on Jupiter?
Moving at constant velocity doesn't require any force, regardless of the object's mass or where it is.
Does unbalanced forces maintain motion at constant velocity?
No. If the forces on an object are unbalanced, that means their sum is not zero, and there is a net force on the object. Since there is a net force on it, the object is accelerated, which is another way of saying that its velocity changes.
What law that states that every object maintain constant velocity unless acted on by an unbalanced force?
Newton's 1st law'
Is a force needed to keep a moving spacecraft moving in a straight line?
It depends where the space craft is. If it is in deep space far away from any large mass (like a planet, star, etc) then the answer is no. If it is close to a mass then the answer is yes. An equal and opposite force is required to balance the gravitational force to keep it moving in a straight line.
