Balanced forces mean the net force is zero. This is true. When all the forces acting on an object cancel each other out, the net force is zero.
Zero net force doesn't always mean the object is stationary. This is the key! An object can have balanced forces and still be:
* Moving at a constant velocity. Think of a car cruising down a straight road at a steady speed. The engine's force is balanced by friction and air resistance. The car isn't accelerating, but it's still in motion.
* Moving in a circle at a constant speed. A ball on a string being swung in a circle has a constant speed but is constantly changing direction. The tension in the string provides the centripetal force to keep the ball moving in a circle. This force is balanced by the ball's inertia (its tendency to move in a straight line).
In summary:
* Balanced forces mean no acceleration. The object's velocity (speed and direction) remains constant.
* Constant velocity doesn't mean being stationary. It can mean moving at a steady speed or moving in a circle at a constant speed.
