Question

13.
A pencil rolls off your desk and falls toward the ground. Why do you see the pencil fall toward the ground, but you don't see Earth fall toward the pencil?

Because gravity only acts on small objects, not planets

Because the Earth does move towards the pencil, but the movement is too small to notice

Because the pencil is lighter than the Earth, so it falls faster

Because the Earth is fixed in space and cannot move

Answer 1

Because the Earth is much larger and more massive than the pencil, so the force of gravity between the Earth and the pencil causes the pencil to fall towards the Earth. The movement of the Earth towards the pencil is too small to be noticeable due to the Earth's size and mass.
