Which of the statements is true A moving object which has no force acting on it keeps a steady speed OR A moving object which has no force acting on it will loose its speed?

The first statement is true. Force implies acceleration on an object. No acceleration means no change in velocity or change in speed. No acceleration means 0=dv/dt thus v=constant.
The constant v can be positive, negative or zero. A.
According to Newton's laws of motion, an object which has NO forces acting on it will continue to move at constant speed in the same direction forever.
This seems wrong. But that's because (in our "normal" experience), just about every object is subjected to the forces of friction and air resistance - so moving objects do slow down...but they have forces acting on them - and your question is about objects with NO forces acting on them.
Even objects out in space where there is no friction and air resistance are affected by gravity - so they don't move at a steady speed in a straight line either. The International Space Station orbits the earth because the earth's gravity forces it to move in a circle.

When a car is allowed to coast on a level road it slows down and stops. is this a violation of newtons first law of motion?
No it is not because there is a friction force opposing the car's forward motion and this is what makes it slow down and stop. There is friction in the tires because they are compressed and released as each part of the tire touches the ground. There is friction in the wheel bearings, and there is the friction of the wind on the front of the moving car. Compare this with a planet in space with has virtually no friction opposing its forward motion so that it is able to continue for possibly billions of years.
What is the basic concept of the steady state theory why it failed and its lapses?
universe was not created and cannot be distroyed is the main concept of steady state theory. it was not able to tell following things; 1.why galaxies are moving. 2.it said that new galaxies form between old galaxies.but it is not seen till today.
What is the noun form of steady?
The correponding noun to the adjective steady is steadiness.
What is a steady drop in temperature called?
a steady drop in temperature is called a gradual front
How can an object be motionless and in equilibruim?
an object that is not moving can be in equilibrum. an object moving at a steady speed in a straight line can also be equilibrum.
If a car is moving at a steady speed of 50 mph what forces will be acting on it?
65
Why does an object in deep outer space carry on moving at the same steady speed even if there are no forces acting on it?
Because there's nothing to stop it. Newton's 1st law of motion states that an object at rest will stay at rest, and a moving object will continue to move at the same velocity, unless a force acts upon it. A moving car stops when it loses power because of friction between the tires and the road acting upon it, a thrown ball loses forward velocity and gains downward velocity because of gravity acting up on it; nothing stops moving, or moves slower, unless an outside force causes it to do so.
What makes a rocket reach a steady speed?
When all the forces acting on it are equal, just like any object.
What is a way to balance steady?
Look at any thing still or stare at a not moving object like door or chair etc.
Why is no work done no an object when a force acting on the object dose not move?
It's a play on words (try holding a weight steady at arms length) that's totally dependent on the definition of "work".
When is a body in equilibrium?
A body is refered to be in equilibrium when the forces acting on it cancel each other out, that is, the body has no resultant force. because F=ma , it can also be stated that a body is in equilibrium when there is no acceleration or deceleration in any direction. Therefore, if a body is moving at a steady speed, although it IS moving, it is still at equilibrium. We normally do not think of a moving object as one in equilibrium but that is because in an actual situation, air drag would cause an object to be in equilibrium with 0 velocity.
What opposes the motion of one object moving past another?
Friction opposes the motion of one object moving past another. Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a force acts on them.
How do unbalanced forces differ from balanced forces?
An object with no force on it will either be at rest or moving with a steady velocity, an object with an unbalanced force, which is the same as saying it has a net force on it, will be accelerating (or decelerating)
What is it when you add two forces acting on an object?
Two forces acting in the same direction cause the body to speed up (accelerate) if the forces are acting in opposite directions, subtract one from the other. The difference is the net force on the body and will be the direction in which it accelerates. Obviously, if they're the same size and opposite in direction, providing the body is rigid (it doesn't deform, in other words), the stat of motion of the body will stay the same (either at rest or moving at a steady speed in a straight line).
An example of zero acceleration would be what?
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
What is keeping a steady beat?
Keeping a steady beat is important when two people are moving to music. Otherwise they would get out of step
