What force is acting on a body moving with uniform speed on a perfectly smooth road?

1) There are always frictional forces, which by themselves would slow the car down.
2) Since we are assuming that the car is moving at a uniform speed, there must be another force to compensate for the friction, and in the opposite direction (pulling the car forward). This force is related to the effort done by the engine.

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.
What does smooth surface look like under a micropscope?
its depends how smooth it is, if it is perfectly smooth then it will look like a smooth surface, if it just feels smooth then more than likely it will be covered in bumps and crevasses
Can unbalanced forces stop a moving object?
Yes.For the velocity of an obejct to change (e.g. to make a moving object slow down and stop) there must be a resultant force acting on it. This only occurs if the forces acting on it are unbalanced.Yes.For example :When we cycle fast and while going if we cross a speed breaker or an area of the road which is not smooth , there will be more friction thereby reducing the speed of the object or otherwise stopping it.
As you go down a SLIDE your movement is not smooth what can you infer about the force acting on you?
Gravity is the force that is pulling you down. However, friction is acting against gravity to keep you in place, since you are rubbing against the slide. So the quick answer would be friction.
What is lamelar flow of fluid?
Laminar flow is smooth flow : all the molecules of the liquid are moving in the same direction. (but not necessarily at the same speed - it never is).
How smooth is a cue ball?
It is perfectly smooth.

What does deft mean?
deft: adjective: moving or acting in a quick, smooth, and skillful way; clever, showing good sense and skill in achieving or acquiring things.
What kind of frictional force is acted upon smooth surface?
If it is perfectly smooth then only sliding friction.

Why does some friction occur with seemingly smooth surfacers?
Because on the molecular level, they are not smooth No surface is perfectly smooth and even if it were, many molecules of the two surfaces would get close enough together to interact.

Do most satellites in the outer solar system have perfect smooth surfaces?
No. No object in the solar system has a perfectly smooth surface. These satellites have craters, mountains, and valleys.
