Claim: When the forces on the object were balanced, it maintained a constant state of motion, either remaining at rest or moving at a constant velocity.
Evidence: In this situation, the left force of 150 N and the right force of 150 N were equal in magnitude and opposite in direction, resulting in no net force acting on the object.
Reasoning: Since the net force was 0 N, as the forces canceled each other out, the object did not accelerate or change its state of motion, illustrating Newton's first law of motion.
