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.

∙ 13y agoFor an object to be in constant motion (i.e. constant velocity), the net force acting on the object must equal 0. For example, if a block was sliding on a friction-less plane at a constant velocity, then no force would be needed to maintain that velocity. If however the plane DID have friction, then a force equal to the force of friction would be needed to maintain constant velocity.

∙ 8y agono, the inertia of the body alone keeps it moving

How much force is needed to keep a 2kg object moving?
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.
Is net force needed to change the speed or direction of moving matter?
Yes, that's a firm. Net force is needed in order to change the speed or direction of moving matter. Uh huh.
Desciption of newtons first law of motion in everyday terms?
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.
Why do winds deflect instead of moving straight to the north or to the south?
Due to the Coriolis Force (as a consequence of the earth's rotation)
Is it impossible when an object moving in a straight line has no acceleration?
If a body is moving at constant velocity in a straight line, the acceleration is zero and the net force acting on it is zero. F = ma F = m x 0 F = 0
How much force is needed to move an object?
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.

What is needed to change the direction of a moving mass?
The answer is force because Force is needed to change the direction of a moving mass.
A force that slows or stop a moving object is?
straight
What outside force prevents the planets from moving in a straight line into space?
The force of gravity.
A spacecraft orbits Earth at a constant speed.The forces actinbg on it must be?
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.
How does moving fulcrum on a lever change the amount of force needed to move an object?

What is the force needed to move an object and the distance it is moved in the direction of the force?
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.
Objects moving at a constant speed in a straight are said to be in?
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
What is a measure of the amount of force needed to move an object a certain distance?

Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
