Final answer:
An object with more mass requires more force to achieve the same acceleration as an object with less mass, based on Newton's second law of motion, which relates force, mass, and acceleration.
Step-by-step explanation:
According to Newton's second law of motion, an object with more mass requires more force to achieve the same acceleration as an object with less mass. This is because the second law defines the relationship between force (F), mass (m), and acceleration (a) with the formula Fnet = ma, indicating that force is directly proportional to mass and acceleration, and inversely proportional to acceleration when rearranging to solve for acceleration (a = Fnet / m). Hence, if the mass is greater, more force must be applied to achieve a certain acceleration. This relationship also tells us about inertia, as the mass of an object is a measure of its inertia, the tendency to resist changes in motion. Therefore, applying the same force to two objects will result in different accelerations if they have different masses.
