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.
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
Yes, a net force is needed to change the speed or direction of moving matter. Newton's first law of motion states that an object will remain in its state of motion unless acted upon by an external force. When a net force is applied, it can accelerate the object, decelerate it, or change its direction.
Anything that's moving keeps moving in a straight line at constant speed, unless a force acts on it.Anything that's not moving can't start moving, unless a force acts on it.Any change of speed or direction needs a force to make it happen.
On Earth, there is friction and air to slow vehicles down. There isn't any in space therefore they do not slow you down. As for gravity, it is much less in space. The amount of gravity depends on how close/far you are from a planet as to what the speed does, whether increase or decrease. This decrease in gravity allows a vehicle to move more freely,with the absence of friction and air to slow the vehicle. Thus space movement can be defined as how close the vehicle is to a planet, which will in turn affect the amount of gravity and either slow down or speed up the vehicle. The closer it is to a planet, the more gravity and the faster it will go. The further away it is, the less gravity and the slower it will move. But above all else, it could move indefinitely with the absence of air and friction to slow it down.
forces of body depends on the path it is moving for example if it is moving in straight path it under go forces like frictional forces and forces applied on it if the body is moving in slant path it has frictional force,acceleration due to to gravity(which acts down wards)

The force that keeps a ball moving in a circle is called centripetal force. This force acts towards the center of the circle and prevents the ball from moving in a straight line.
The inward force needed for circular motion is called centripetal force. It is directed towards the center of the circle and is required to keep an object moving in a curved path instead of a straight line. Without this force, the object would continue in a straight line tangent to the circle.
There is no such thing as an amount of force needed to move a certain distance. Asteroids, comets, moons, and planets have been moving trillions of miles through space for billions of years with either no force on them at all, or no force in the direction they're moving. You may have heard of Newton's First Law. It says that an object with no forces acting on it keeps moving in a straight line at a constant speed, which is kind of another good way of saying that it can move as far as you want it to with no force on it.
No, centripetal force is not acting when a body is moving in a straight line. Centripetal force is required to keep an object moving in a curved path.

Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
There is only one force acting on an orbiting spacecraft ... the force of gravity.It's NOT correct to say that a constant speed in a curved path indicates balanced forces.That's true only when the constant speed is in a straight line. If the direction is changing,there must be net forces on the moving object, even if its speed is constant.
true
The force needed to stop a moving object is equal to the object's mass multiplied by its acceleration. This force is generated by applying a force in the opposite direction to the object's motion, causing it to decelerate until it comes to a complete stop.
