it happens when an object has an equivalent forward and back ward force
[object Object]
"Balanced forces" means that the sum of all forces acting on an object - i.e., the resultant force - is equal to zero.
A unbalanced force is the resultant of one or more forces acting on a body which is not zero.
The magnitude of the resultant force in the case of the concurrent forces in equilibrium.
Net Force, Or Net Resultant Force, or Resultant force
A couple.
If they are not coplanar, you would need at least four forces to get a net force (resultant force) of zero.
[object Object]
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
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 zero; it depends. For example two people on a sse saw at same weight and same distance from fulcrum is zero moment but there is force at fulcrum equal to twice their individual weight
a resultant vector not only the resultant of two or three vector. it is the resultant direction of two or many vectors.(let us push an object with same force in opposite direction the resultant is zero and if we push in same direction the force will double.if we pull a object with same force in x and y direction the resultant force in 45 degrees to x axis)
It is certain that two vectors of different magnitudes cannot yield a zero resultant force.
The resultant is a trigonometric function, usually using the Law of Cosines in two dimensional solution by vector resolution, of two or more known forces while equilibrant is equal in magnitude to the resultant, it is in the opposite direction because it balances the resultant.Therefore, the equilibrant is the negative of the resultant.
That the forces sum to a non-zero resultant.
