Here's why:
* Balanced forces: This means the forces acting on the object are equal in magnitude and opposite in direction.
* Net force: The overall force acting on the object is zero because the balanced forces cancel each other out.
* Newton's First Law of Motion: This law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net force.
In simpler terms: Imagine you're pushing a box with your right hand and your friend is pushing the box with the same amount of force in the opposite direction with their left hand. The box won't move because the forces are balanced.
