Here's why:
* Balanced forces are equal in magnitude (strength) and opposite in direction.
* Net force is the overall force acting on an object, calculated by adding all the forces together.
* Because balanced forces cancel each other out, their combined effect is zero.
Example: Imagine pushing a box with 10 Newtons of force to the right, and your friend pushing the box with 10 Newtons of force to the left. The forces are balanced, so the net force is zero, and the box won't move.
