Claim: When the forces acting on the object were unbalanced, it caused the object to accelerate to the left.
Evidence: In this scenario, the left force exerted was 150 N, while the right force applied was 100 N. The net force can be calculated by subtracting the right force from the left force, resulting in 150 N - 100 N = 50 N to the left.
Reasoning: Since the net force of 50 N is directed to the left, the object experiences acceleration in that direction, illustrating the effect of unbalanced forces on motion.
