You should have friction between the box and the ground, the force you used to push it, the mass of the object, and gravity. The resistance of the air is neglibible. This should be all the forces on an object on flat ground.

What is the resistance or drag you encounter when you pull an object across the floor?
This resistance is officially known as friction.
Can you give an example where balanced forces are acting but the object is still in motion?
Consider a basketball rolling across the floor of the gym. Maybe that's not a great, impressive example. But it's important to jump in here and point out that nobody ever said that an object is motionless in the presence of balanced forces. The principle is that an object experiences no acceleration without a net force acting on it, and that without a net force ... with all forces 'balanced' and adding up to zero ... the object remains in constant, uniform motion, i.e. without acceleration.
Why does a ball come to stop when it is rolled across the floor?
Because of the forces that act on the ball in the direction opposite to its motion ... air resistance and friction with the floor.
Pull horizontally on a crate with a force of 140 N and it slides across the floor in a dynamic equilibrium How much friction is acting on the crate?
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
What do unbalanced forces cause an object to do?
An unbalanced force causes a change in the motion of the object that the forces are acting on. It causes acceleration, which can be positive or negative, depending on the direction of the reultant force. Positive means that the object is gaining acceleration and reaching a higher instantaneous velocity every second, while negative means that it's getting slower per second (braking, for instance). Both are examples of motion.

The predicate in this sentence is across the floor. :)

What causes unbalanced forces?
you are not considering the "hidden" force of friction and/or gravity in your thinking. Example: A box sitting at rest on a floor has balanced forces: no force pushing from any of the four sides Balance force up and down (gravity pulling box down, floor holding it up) Now, someone pushes the box across the floor: Initial push causes and acceleration (going from zero velocity to say 5 mph) Now, if that person maintained the 5 mph speed (no acceleration) of pushing the box then we are back to a balanced force: the pushing on the side of the box = the friction on the bottom of the box. Unbalanced forces can cause an object move from its original position resulting in acceleration because every object in the universe has an internal force [resisting force] in it . when an external force applied on an object increases from that of the internal force of the object then that force is said to be unbalanced force
When was Across the Nightingale Floor created?
Across the Nightingale Floor was created in 2002.
When an object is in rest all the forces acting on it are in what?
All the forces acting on each other are in equilibrium. For instance the restoring force upward from the ground/floor is equal to the strength of the force of gravity, which acts downwards.
What are two forces that act on objects?
Typically there is the force of gravity pulling an object down, and a force that keeps it up - for example, the floor on which an object is standing pushes it up. There may be additional objects involved.
