Final answer:
The statement about the large snowball being harder to move than the smaller one exemplifies Newton's Second Law of Motion, which relates force, mass, and acceleration.
Step-by-step explanation:
The statement "The large snowball was much harder to move than the smaller one" illustrates Newton's Second Law (Law of Acceleration). This law explains the relationship between force, mass, and acceleration. It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In the case of the snowballs, the larger one has more mass and hence more inertia, making it require a greater force to achieve the same acceleration as the smaller snowball. This directly ties the concept of mass to its resistance to changes in motion, which is inertia, as mentioned in Newton's First Law (Law of Inertia). However, since we are discussing the difficulty of causing acceleration (changing the velocity of the snowballs), it more specifically relates to Newton's Second Law.
