Question

the motion of each ball is changed when it is hit with the bat. the bat hits each ball, and also each ball hits the bat. newtons second law of motion newtons first law of motion

Explanation:

Step1: Recall Newton's laws

Newton's first law (law of inertia) states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Newton's second law is \(F = ma\) (force equals mass times acceleration). Newton's third law states that for every action, there is an equal and opposite reaction.

Step2: Match the statements

• When the motion of the ball is changed (its velocity changes, so there is an acceleration), this is related to Newton's second law (\(F=ma\), force causes a change in motion/acceleration).
• When the bat hits the ball and the ball hits the bat (action - reaction pair), this is related to Newton's third law. But since the given options are first and second, and the first statement is about change in motion (acceleration), and the second statement (though it's a third - law concept in reality, but if we assume mis - labeling in the problem setup and we have to choose from first and second) the first statement (change in motion) is Newton's second law and the second statement (interaction) is not a correct match for first or second. But if we consider the first part (bat hitting ball changes ball's motion - force causes acceleration) is second law (\(F = ma\)), and if we assume the problem has an error in options (maybe it was supposed to have third law but has first and second), but based on the given:

The first box (motion change) is Newton's second law. The second box (interaction) - if we have to choose from the given options (first and second) and since the first law is about inertia (no force vs force), and the second is about force and acceleration. But actually, the second statement (bat and ball hitting each other) is a third - law concept. But if we follow the problem's structure (matching to given first and second):
Assume the first statement (change in motion) is second law (\(F = ma\) - force causes acceleration, change in motion).

Answer:

First blank: Newton's second law of motion
Second blank: (There is an error in the problem as it should relate to third law, but if forced to choose from given) no correct match (but if we assume a mis - understanding and consider the first law is about no force (object in motion stays in motion unless...), and the second is about force causing acceleration. But the second statement (interaction) is not a first or second law concept. However, if we follow the problem's intended (maybe wrong) structure: First blank: Newton's second law, second blank: (no correct option as per actual laws, but if we consider the problem's mis - alignment) no answer (but since we have to choose from given): If we assume the first is second law (change in motion - \(F=ma\)) and the second (even though it's third law concept) - if we have to pick from first and second, there is no valid pick. But if we follow the problem's likely intended (wrong) match: First: Newton's second, second: (no correct as per laws but if we assume the problem confused interaction with first law (which is not), but no. So strictly: First: Newton's second law of motion. Second: (no correct option from given first and second as per physics laws, but if we have to write something, maybe the problem had a typo. But based on the first statement: change in motion - second law (\(F = ma\))).
