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.

∙ 10y agoYes, because the first law of motion explains the state of motion of an object does not change until a force acts on it , that means a thing that will go into a straight line until another thing changes it motion. And Also there usa force needed to overcome inertia when rocket takes off.

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.
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.
The centripetal force of a body having mass m and rotating at a linear speed of v in a circle of radius r is given by mvr mvr mv2r mvr2?
none of the above Force centripetal = (mass * velocity^2) ÷ radius More mass , more force needed to keep object in the circle Object going faster, more force needed to keep object in the circle Larger radius, less force needed to keep object in the circle That is why mass and velocity are in the numerator ( multipliers) and Radius is in the denominator ( divider)
When the box is moving it experiences a friction force of 20 N to the left or toward the mover What force does the mover need to apply in order to keep the box moving to the right at 1 m s?
Since the box not having any acceleration and is moving with constant velocity the net force on the box is zero. Therefore the mover needs to apply a force of 20 N.
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.
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.

Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
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 provides the centripetal force needed to keep the stopper moving in a circle?
The string

Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
Does it take the same amount of force to start something as it does to keep it moving?
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

The inward force needed to keep an object moving in a circle?
The force that keeps objects moving in a circle is known as the centripetal force, which acts towards the center. The velocity of the object moving in a circle will be tangential to the circle.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
What force keeps a space probe moving?
No force is required to keep something moving. According to Newton's Second Law, you need a force to speed something up, or to slow something down - not to keep it moving.
