Question

Quizplus · Accepted Answer

An unbalanced force acting on an object will cause it to accelerate, according to Newton's second law of motion. This change in acceleration will result in a change in velocity, which is why option A is correct. Options B, C, and D describe scenarios where forces are either balanced or changed uniformly, which would not result in a change in velocity if the forces remain balanced.
