Consider an apple at the top of a tree that is pulled by Earth’s gravity with a force of 1 N. If the tree were twice as tall, would the force of gravity be only ¼ as strong? Defend your answer.

Answer 1

Absolutely not, gravitational force depends directly on the product of the masses-of the two objects and inversely proportional to the square of the distance between the center of mass of the two objects. In this case the center of the apple and the earth’s center thus a tree height is statically insignificant.
