You and I stand on opposite ends of a small car.
You are in the back, pushing it forward with a force of 100 pounds. I am in the front, pushing it backward with a force of 100 pounds.
I don't know what the "force" on the car is. Is it 200 pounds, 100 each from you and me ? Do we also have to add in the weight of the car ... another 2,000 pounds of gravity pushing it downward ? How about the reaction force of the pavement ... another 2,000 pounds pushing it upward ? I don't know.
But I do know the net force on the car ... it's zero. The two horizontal forces on it cancel each other, because they're directed in opposite directions. Same for the vertical forces. Which is why the car doesn't accelerate in any direction ... because the net force in that direction is zero.
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
Not necessarily. The net force being 0 means the object is in translational equilibrium, but the net torque can still be non-zero if there are unbalanced forces causing rotation.
If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).
If an object has no net force acting on it, it will either remain at rest or continue moving at a constant velocity in a straight line, following Newton's first law of motion.
Zero net force means there is no overall force acting on an object, thus the object will either remain at rest or continue moving at a constant velocity (Newton's First Law). This state of motion is known as equilibrium.
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.

Equilibrium
If an object is in static equilibrium (or "stable"), there is no net force acting on the object.
zero
It is in equilibrium.
No, an object cannot be in equilibrium if it is moving. Equilibrium is a state where the net forces acting on an object are balanced and there is no acceleration. If an object is moving, there must be an unbalanced force acting on it causing its motion.
Yes, that's correct. When the net force acting on an object is zero, the object is in equilibrium. This means that the forces are balanced, and the object will remain at rest or continue to move at a constant velocity.
If an object is not in equilibrium, it will experience a net force acting on it, causing it to accelerate in the direction of the force. This acceleration will change the object's velocity and possibly its position.
what is an essential characteristic of an object in equilibrium
Yes, if the velocity is a constant with no net force.
