When you step on a weighing scale at noon,the Earth pulls you down and the overhead sun pulls you upward.The reason the sun's pull doesn't decrease your weight at noon is because
A)the sun's pull on you is negligibly small.
B)the weighing scale is calibrated only in Earth weight.
C)you,the scale,and the Earth are in free fall (in orbit)around the sun.
D)the sun's pull is cancelled by the gravitation of other celestial bodies.
E)of tidal effects in the "solid" Earth.

At noon, when you step on a weighing scale, you, the scale, and the Earth are in free fall around the sun. This means that the gravitational forces between you, the scale, and the Earth are balanced, and you don't feel the effect of the sun's pull on you. It's like being in an elevator that's falling freely - you feel weightless because the force of gravity is not acting on you.
