Answer:
The gravitational potential will change more on earth.
Explanation:
The gravity on the moon is only 17% of that of earth's because the earth has way more mass. Since the gravitational potential depends on the mass of the human and the height of the ladder, and both things will remain equal, no matter where they are, so we could assume that the gravitational potential energy will change more on earth.

Aliyah happened once more, as in the times of Abraham and Moses.
The least developed nations tend to have lower levels of industrial activity, resulting in lower levels of environmental damage. The most developed countries have found ways of improving technology and energy efficiency to reduce their environmental impact while retaining high levels of production
