Final answer:
To maintain the same acceleration when mass is increased, you must increase the net applied force proportionally, as dictated by Newton's second law of motion, Fnet = ma.
Step-by-step explanation:
The question relates to Newton’s second law of motion, which is represented by the formula Fnet = ma, where Fnet is the net force applied to an object, m is the mass of the object, and a is the acceleration of the object. From this equation, we understand that force is directly proportional to the mass when acceleration is constant. Therefore, if the mass is increased and you want to maintain the same acceleration, you would need to proportionally increase the net applied force.
For example, if you double the mass of an object, you must also double the force to achieve the same acceleration. This is because acceleration is inversely proportional to mass - as one goes up, the other must go down for the product (force) to stay the same. Thus, to maintain the same acceleration, any change in mass requires an equal proportional change in force.
