Two children on a seesaw are able to balance perfectly while on Earth. Would they still be balanced if the seesaw was brought to the moon?(1 point)
Bailee explained that when traveling to the moon, he needs to pack light because the weight of objects on the moon is the same as their weight on Earth. The mass of the objects is what changes when the gravitational pull changes. Is Bailee correct in his explanation?(1 point)

Bailee is incorrect. Both the mass and weight will stay the same.

No, the children would not be balanced on the moon. The balance of a seesaw is dependent on the gravitational force acting on each side. On Earth, the force of gravity is relatively constant, causing the balance. However, the moon's gravity is only about 1/6th of Earth's gravity. This means that the force pulling the children towards the center of the moon would be much weaker. As a result, the seesaw would not balance unless there are adjustments made to the weight distribution on each side of the seesaw.
To determine whether the children on the seesaw would still be balanced on the moon, we need to consider the factors that affect the balance on a seesaw.
A seesaw balances due to the principle of moments, which states that the total moment (or torque) on one side of the pivot point must be equal to the total moment on the other side in order to achieve balance. The moment is the product of the force applied and the distance from the pivot point.
On Earth, the children are balanced because their weights exert equal and opposite forces on either side of the pivot point, creating equal moments. However, the weight of an object depends on the gravitational force acting on it.
On the moon, the gravitational pull is weaker compared to that on Earth, approximately one-sixth of Earth's gravity. This means that the weight of the children, and hence the force they exert on the seesaw, would be significantly reduced on the moon.
Since the forces exerted by the children would be different on the moon, their weights would no longer be balanced, and the seesaw would not be balanced either. The child with a greater weight would cause the seesaw to tip towards their side.
In conclusion, if the seesaw is brought to the moon, the children would not be balanced on it due to the difference in gravitational force and their weights.
