There is less gravity on the Moon. Gravitational potential energy can be calculated by multiplying weight x height, or the equivalent mass x gravity x height.
At 100 meters this rock's potential energy is 980 joules.

Assuming that the two are the same man ... the man diving from a 10 meter board would have five times the potential energy as the man on the 2 meter board. The energy is directly proportional to the height.
the material of sitting heigth is meter stick only
The potential energy that the box gained only depends on how high it was raised, not on how it got there. If both boxes started at the same height and ended at the same height, then they both gained the same amount of potential energy.
A 10kg hammer at a height of 450 meters has potential energy of 44,100 joules. (PE = m x 9.8 x h)
(Gravitational) potential energy = mgh (mass x gravity x height). Those are the three factors. In standard units (SI), mass is given in kg., gravity is around 9.8 meter / second square, and the height should be given in meters.
Potential energy takes many different definitions, but the most common is due to gravity. Say move a book from the floor to a shelf that is one meter above the ground. The book has a mass of 2 kilograms. While the book is on the floor, it has zero potential energy. Since potential energy is defined as the height times the mass times the gravitational constant, and height is equal to zero at that point, there is no potential energy. But when it is moved to one meter high, the math goes as follows: 1 meter X 2 kilograms X 9.8 meters per second squared(The gravitaional Constant) = 19.6 Joules(The unit of potential energy).
