智力题
“Why is a half moon heavier than a full moon?”
如果是脑筋急转弯的话(智力大冲浪)
Because the full moon is lighter.
light意思可以是亮的也可以是轻的.
也可以这个
when a half moon ,earth is in between the sun and the moon,so the moon experiences gravitional forces by both the earth and the sun.
When the moon is full,it is in between of the earth and the sun.The attraction force to the earth is reduced by the attraction force to the sun.
