Explanation:

Based on the references, the calculated potential energy is the same if the reference used is the same or different.

Potential energy is the energy due to the position of a body.

It is the energy at rest in body.

The change in potential energy is given as:

ΔE = E₂ - E₁

E₂ is the final potential energy and E₁ is the initial potential energy.

Since when the body comes to rest after falling through a height, the final potential energy is 0.

The change in potential energy does not depend on the reference.
