In the outer space there is no matter to get the reaction force (so newton's third law fails for rocket propulsion ) but here comes the concept of "fluid momentum transfer" that is
when ever fluid moves at certain velocity it tries to move in straight path and this fluid transfers its momentum when there is sudden change in its direction.
well to understand this phenomenon i can quote you a simple daily life example "water sprinkler works on same concept"

Why areal velocity is constant in central force?
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.
How can a boat move at constant velocity if its propeller provides a steady force to it?
Terminal velocity, where the driving force = drag force from the water
When does centripetal force double?
Since a=Rω², when you double the radius, but hold the angular velocity constant, you double the force. Also when you increase the angular velocity or velocity by a factor of √2 and hold the radius constant.
How is constant velocity and equilibrium related?
Constant velocity gives zero acceleration, force is mass times acceleration, thus if acceleration is zero then force is zero and equilibrium is zero force. Equilibrium = zero force :0=f=ma=mdv/dt = m0 when velocity is constant dV/dt=0.

Would a rocket travel at a constant speed?
Assuming its engines are off, it would travel at a constant speed ONLY if there is no force of gravity that changes its velocity. In practice, there are always forces that will change its velocity, at least in the long term.
What is velocity if the net force is 0?
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
What is the net force acting on a car cruising at a constant velocity of 70 kmh on a level road?
If the velocity is constant (no acceleration), the net force is zero.
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.
What is the acceleration of of an object that moves at a constant velocity and it net force?
The acceleration of an object with constant velocity is zero. It's force will be Mv^2 where M is it's mass and v is it's velocity.
How can a boat move at constant velocity if its propeller provides a steady force to it?
Terminal velocity, where the driving force = drag force from the water
What is Motion without acceleration?
Such and object is said to be in equilibrium. No acceleration and no force.
When does centripetal force double?
Since a=Rω², when you double the radius, but hold the angular velocity constant, you double the force. Also when you increase the angular velocity or velocity by a factor of √2 and hold the radius constant.
