Here's why:
* Balanced forces: These are forces that cancel each other out, resulting in no net force.
* Equal and opposite: For forces to be balanced, they must have the same magnitude (strength) but act in opposite directions.
Example: Imagine pushing a box with a force of 10 Newtons to the right. If someone else pushes the box with a force of 10 Newtons to the left, the forces are balanced. The box will not move because the forces cancel each other out.
Important note: While balanced forces result in no change in motion (either at rest or constant velocity), it doesn't mean there are *no* forces acting on the object. It just means the forces are equal and opposite.
