Hydrogen balloon naturally moves from low altitude to high altitude in Earth's atmosphere. Any object moves from higher to lower potential. So can we call low altitude high potential region?

Potential what? If you clarify what "potential" you're talking about, you'll answer your own question.Himal kharel said:Hydrogen balloon naturally moves from low altitude to high altitude in Earth's atmosphere.

It would help if one were to distinguish between gravitational potential and bouyancy. As a hydrogen balloon rises and the atmosphere thins, there is less difference between the effective density of the hydrogen balloon and that of the atmosphere.Himal kharel said:Consider two points in Earth's atmosphere A(high altitude) and B(low altitude). In order to take stone from B to A we need to do some work which is stored as potential energy in the stone. So point A is high potential region for objects that have natural tendency to fall.
But for hydrogen balloon we have to do work in order to take it from point A to B. Similarly work done is stored as potential energy. So point B is at high potential than A.
If anything is wrong with my explanation please correct it.
Thanks
For completeness, you should split the problem into the two different types of potential energy you are seeing: one due to gravity alone, the other due to buoyancy. Both apply to the rock as well, you're just ignoring the buoyancy of the rock.Himal kharel said:Consider two points in Earth's atmosphere A(high altitude) and B(low altitude).

Potential energy is the energy that an object possesses due to its position or configuration.
In the case of a hydrogen balloon, the potential energy is a result of the gravitational force acting on the balloon due to its position in the Earth's atmosphere. The higher the balloon rises, the greater its potential energy becomes.
Yes, the potential energy of a hydrogen balloon can be calculated using the equation PE = mgh, where m is the mass of the balloon, g is the acceleration due to gravity, and h is the height of the balloon.
As the hydrogen balloon rises, the potential energy increases due to its increasing height. However, as the balloon descends, the potential energy decreases as its height decreases.
The potential energy of a hydrogen balloon is affected by its mass, the strength of the gravitational force, and its height or position in the Earth's atmosphere.
