Here's why:

* Balanced forces: This means the forces acting on the object are equal in magnitude and opposite in direction.

* Net force: The net force, which is the overall force acting on the object, is zero when forces are balanced.

* Newton's First Law: Newton's First Law of Motion states that an object at rest stays at rest, and an object in motion stays in motion at a constant velocity, unless acted upon by a net force.

In other words, if the forces are balanced, they cancel each other out, and there's no force to change the object's velocity. The object will continue moving at the same speed in the same direction, or if it's at rest, it will stay at rest.
