Final answer:
Causes a change in an object's motion is not a characteristic of balanced forces. Balanced forces occur when the forces acting on an object are equal in magnitude and opposite in direction, resulting in a net force of zero.
Step-by-step explanation:
Causes a change in an object's motion is not a characteristic of balanced forces. Balanced forces occur when the forces acting on an object are equal in magnitude and opposite in direction, resulting in a net force of zero. This means that the object would experience no change in its motion, as there is no unbalanced force acting on it to cause acceleration or deceleration. Balanced forces do not cause a change in an object's motion. When forces are balanced, the net force acting on an object is zero, meaning the forces are canceling each other out. In this case, an object at rest stays at rest, and an object in motion continues to move at a constant velocity (which may be zero if the object is at rest). Changes in motion occur when unbalanced forces are applied, causing acceleration or deceleration. The other options (a, b, and d) are characteristics of balanced forces.
