A physics teacher poses the following question to her class: "We all know that the Earth pulls on the moon, but does the moon pull on the Earth? If so, which exerts a greater force?" The following students offer their answers and justifications. If the Earth pulls on the moon, then the moon must Student 1 also pull on the Earth. The forces they exert on each other would have to be equal and opposite. If the Earth pulls on the moon, then the moon must also pull on the Earth. But the Earth is much larger Student 2 and heavier than the moon, so the Earth will exert a greater force. The Earth pulls on the moon due to gravity but the Student 3 moon doesn't have gravity so it can't pull back on the Earth. The Earth pulls on the moon but the moon is so far Student 4 away that it can't pull back on the Earth. Which student's answer is the most accurate?
