That's the way our Universe works; that's the natural tendency of any object - to keep moving at the same velocity (same speed and in the same direction). However, in our everyday experience this isn't so obvious, because there are normally forces of friction at work, that slow objects down.

An object in space will keep moving at the same speed due to the absence of friction or external forces. According to Newton's first law of motion, an object in motion will remain in motion unless acted upon by an external force. In the vacuum of space, where there is no air resistance or other forces to slow it down, the object will continue to move at a constant velocity.

What force keeps an object in free space going a constant speed?
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
What will happen to an object if the sum of all the forces acting on a moving object is zero?
it will keep movin at a constant speed
If instantaneous speed doesn't change?
The car or object will move at that speed if the speed doesn't change. then what nothing the car will keep on moving with the same speed.
What forces enable an object to be in motion?
If an object is moving, no force is required to keep it moving. Forces are required to CHANGE its motion, for example, to speed it up, or to slow it down.
What is necessary for a force to move an object?
No force is required to keep an object in motion. Maintaining speed and direction seems to be "the natural thing to do" for any object. A force is required to CHANGE an object's velocity, whether you want to make it go faster, slow it down, or simply change the direction for a moving object.
What force keeps an object in free space going a constant speed?
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
How is orbit and gravity related?
When it an object in space in moving it will keep moving at the same speed with the property of inertia. Then moon is an object that has inertia. Gravity keeps the moon from going off into outer space but inertia keeps the moon from crashing into the moon. Gravity and inertia have to be balanced in order for an object to remain in orbit.
What will happen to an object if the sum of all the forces acting on a moving object is zero?
it will keep movin at a constant speed
How much force is necessary to keep an object moving in the same speed and direction?
None.
If instantaneous speed doesn't change?

What will happen to the speed of a space ship if it turns off its engines in space?
First of all, remember that it takes force to change the speed or direction of amoving object, but not to keep it moving at a constant speed in a straight line.Whatever the space ship's speed and direction are when the engine is switched off,it continues moving at that same speed and in that same direction, until some forcecomes along to change them. That force might be, for example, a gravitational one,if the space ship's motion brings it close enough to a planet, a moon, or an asteroid.
Is it true that a force is required to keep an object moving in a given direction?
Yes! remember Newton law of movement? An object will keep on moving forever, as long as another force or object leaves it alone. Wonderful! Your second sentence is correct, and totally contradicts your first one. The answer is: No. It is false. No force is required to keep an object moving at a constant speed in a straight line.
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.
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 will an object in straight-line motion tend to do?
An object in motion tends to keep moving in a straight line at a constant speed,unless an external force acts on it to change its direction or speed.
