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.
What else can I help you with?
What force keeps an object in free space going a constant speed?
In free space, an object will continue moving at a constant speed due to its inertia—the tendency of an object to maintain its velocity unless acted upon by an external force. In the absence of external forces like friction or gravity, the object will continue in its state of motion due to Newton's first law of motion.
If instantaneous speed doesn't change?
If instantaneous speed doesn't change, it means the object is moving at a constant speed at that particular moment. This could happen if the object is moving in a straight line without any acceleration or deceleration.
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
What is the relationship between centripetal force and speed?
The centripetal force required to keep an object moving in a circular path increases as the speed of the object increases. This is because the force needed to counteract the tendency of the object to move in a straight line (due to inertia) is directly proportional to the square of the object's speed.
What is the Direction of Acceleration of an object moving on any circular path at constant speed is pointed?
The direction of acceleration of an object moving on a circular path at constant speed is pointed towards the center of the circle. This acceleration is called centripetal acceleration and is necessary to keep the object moving in a curved path.
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 force keeps an object in free space going a constant speed?

If instantaneous speed doesn't change, it means the object is moving at a constant speed at that particular moment. This could happen if the object is moving in a straight line without any acceleration or deceleration.
How much force is necessary to keep an object moving in the same speed and direction?
None.
What is the safest top speed in space?
In space, there is no top speed as there is no friction to slow down an object. The speed of an object in space can theoretically keep increasing as long as there is a force propelling it. However, practical limitations such as fuel supply and structural integrity of the object would determine the safe speed for a spacecraft.
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
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.
What is the relationship between centripetal force and speed?
The centripetal force required to keep an object moving in a circular path increases as the speed of the object increases. This is because the force needed to counteract the tendency of the object to move in a straight line (due to inertia) is directly proportional to the square of the object's speed.
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 the Direction of Acceleration of an object moving on any circular path at constant speed is pointed?
The direction of acceleration of an object moving on a circular path at constant speed is pointed towards the center of the circle. This acceleration is called centripetal acceleration and is necessary to keep the object moving in a curved path.
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.
What will happen to an object if it is put into motion in space, considering the effects of zero gravity and the absence of air resistance?
In space, an object put into motion will continue moving in a straight line at a constant speed unless acted upon by an external force. Without gravity and air resistance, there are no forces to slow it down or change its direction, so it will keep moving indefinitely.
