If the acceleration of an object doubles, what happens to the unbalanced force?

When the acceleration of an object doubles, the unbalanced force acting on the object must also double to maintain the relationship described by Newton's second law of motion, which states that force is equal to mass times acceleration (F = ma).

In this context, if the mass of the object remains constant and the acceleration is increased, the only way to satisfy the equation is for the force to increase proportionally. Therefore, if you initially have a certain force causing a specific acceleration, increasing the acceleration while keeping the mass the same requires an increase in the unbalanced force to double as well. This relationship illustrates how force and acceleration are directly related when mass is constant.

This understanding stems from the fundamental principles of Newtonian physics, emphasizing the proportional relationship between force and acceleration. In this scenario, any option suggesting that the force decreases, remains the same, or triples does not align with the principles established by Newton's second law.
