Balanced forces produce no change in movement. When forces acting on an object are balanced, it means that the forces are equal in size but opposite in direction. This results in a net force of zero, meaning there is no unbalanced force to cause a change in the state of motion of the object. Therefore, if the object is at rest, it will remain at rest, and if it is in motion, it will continue to move at a constant speed in a straight line.

This concept aligns with Newton's First Law of Motion, which states that an object will remain at rest or in uniform motion unless acted upon by a net external force. Thus, with balanced forces, the object either has no movement if it is stationary or continues moving with the same velocity if it is in motion.

The other options describe scenarios that involve unbalanced forces. A change in direction, acceleration, and spinning motion all imply that an external force has acted upon the object to alter its motion, which does not occur with balanced forces.
