Newton's Apple

Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance from the earth of both an apple and the moon in order to measure the force of gravity on each.
