What happens to acceleration when an unbalanced force is increased?

When an unbalanced force acting on an object is increased, the acceleration of that object also increases. This relationship is grounded in Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Mathematically, this can be expressed as ( F = ma ), where ( F ) is the net force, ( m ) is the mass of the object, and ( a ) is the acceleration. If the mass of the object remains constant and the net force increases, the acceleration must also increase in order to satisfy this equation. Therefore, as the unbalanced force increases, so does the acceleration, resulting in the correct choice being that acceleration increases.
