When an object undergoes acceleration-
Correct Answer: A. A force always acts on it
Explanation: According to Newton's second law of motion, an object will only experience acceleration if an unbalanced or net external force is applied to it. This law is mathematically represented by the formula F = ma, which demonstrates that the net force acting on a system is directly proportional to its acceleration. Therefore, whenever an object undergoes acceleration, it is a direct result of a force acting upon it. While factors like gravity can cause an object to move downward, acceleration itself is defined by the presence of a force rather than a specific direction of travel.
