Here's why:

* Balanced forces mean that all the forces acting on the object cancel each other out.

* Newton's First Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity (speed and direction) unless acted upon by an unbalanced force.

Example: Imagine pushing a heavy box. If you push with the same force as your friend pulling it in the opposite direction, the box won't move. The forces are balanced, so the box stays still.

In summary: Balanced forces result in no change in the object's motion. It either stays still or continues moving at a constant speed and direction.
