What happens to acceleration when an unbalanced force is increased?

When an unbalanced force acting on an object increases, the acceleration of that object also increases. This relationship is governed by 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 the mass of the object. The law is often expressed with the formula ( F = ma ), where ( F ) is the net force, ( m ) is the mass, and ( a ) is the acceleration.

As the unbalanced force increases while the mass remains constant, the value of acceleration must also increase. This means that if the force acting on an object becomes stronger, the object will accelerate more rapidly.

In contrast, options that suggest that acceleration decreases, remains constant, or fluctuates do not align with this fundamental principle of physics. An increased force does not result in a decrease in acceleration or a constant acceleration, as the acceleration will always respond to changes in force according to the equation provided by Newton. Therefore, an increase in unbalanced force leads to a proportional increase in acceleration.
