You could say it if you want, but it's not a true statement. Without investigating
the situation in detail, we know immediately that every object on Earth, whether
at rest or in motion, is acted upon by a gravitational force directed toward the
center of the Earth. There are other exceptions to the statement, but we've
already disproven it, utterly and easily.

If no force acts upon an object at rest what will the object do?
If no force acts upon an object at rest it will just stay there. Example: Lets say you put an appple on a flat table. The apple stays still when you don't touch it. If you touch the apple, it will move. If you don't touch the apple, it will just stay there.
Is it correct to say that no force acts on a body at rest?
No, it can be moving. A body is said to be in equilibrium when the forces acting on it cancel each other out, that is, the body is not accelerating. Therefore an object might be moving at a constant speed and be considered in equilibrium.
What will increase accelaration of an object that is pushed by a force?
A net force will cause an acceleration. That is to say, if a net force acts on an object, the object's velocity will change.
When do you say body at rest and when do you say it is moving?
A body is said to be in motion when it changes its position with respect to its immediate sorroundings and it is at rest when it does no changes its position with respect to its sorroundings (immediate).
Would it be say that no force acts on a body moving on a perfectly smooth surface?
It would not be a perfect answer if I said yes because you did not assume that if the body was moving in vacumn. If its not, like for example it is moving on an ice block on the surface of the earth then the object still has gravity and the air friction acting on it. Even the molecules of the ice's surface attract the surface of that object it is in contact with. So if I say that the object is in space then it would be a incredibly correct answer to say yes, there are no force acting on the body.
Is it true that an object at rest will say at rest until a net force acts upon it?
Yes, it is true.
Would it be correct to say that inertia is the reason a moving object continues motion when no force acts upon it?
Yes. Newton's First Law of Motion: Every body continues to remain in its state of rest or uniform motion unless it is acted on by an external, unbalanced force.
Which does not change when an unbalancd force acts on object?
If you mean an external force when you say unbalanced forces, yes. Newton's First Law of motion is also known as law of inertia. Inertia is the movement of mass with out any external forces or influences acting on that mass.
If no force acts upon an object at rest what will the object do?
If no force acts upon an object at rest it will just stay there. Example: Lets say you put an appple on a flat table. The apple stays still when you don't touch it. If you touch the apple, it will move. If you don't touch the apple, it will just stay there.
What happens to momentum when an impulse acts on a system?
Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
True and false the law of intertia states that a body remains at rest or continues in a state of uniform motion unless a force acts on it?
That sounds pretty much like Newton's first law of motion, sometimes calledthe "law of inertia", so I'm going to say "True and notfalse".
What does it mean to say something is in mechanical equilibrium?
It means there are no unbalanced forces, or the net force is zero. That means if a t rest it will stay at rest, or if in motion it will stay in motion with no acceleration.It means that there is no net force acting on the object(s). A body moving at constant velocity is in mechanical equilibrium. A body that is not moving is in static equilibrium.
When does a body accelerate?
A body accelerates when force acts on it. Actually, we should say a "net force" ... if there is more than one force acting on the body, they may have different strengths and come from different directions. Then, we have to combine their strengths and directions to find a single force that's equivalent to all the separate ones. If the strengths and directions are just right, it's possible that they can all cancel each other out ... for example, if there are two forces on the body, with equal strength and exactly opposite directions, they add up to zero, just as if there was no force at all acting on the body. So we should actually say that a body accelerates when the net force on it is not zero.
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
Define newtons first law of motion?
a body remains at rest or in motion with a constant velocity unless acted upon by external force.
Is it correct to say that no force acts on a body at rest?
No, it can be moving. A body is said to be in equilibrium when the forces acting on it cancel each other out, that is, the body is not accelerating. Therefore an object might be moving at a constant speed and be considered in equilibrium.
What will increase accelaration of an object that is pushed by a force?
A net force will cause an acceleration. That is to say, if a net force acts on an object, the object's velocity will change.
