Dear student
 
An elevator descends from the top of a building to a stop at the ground.
The potential energy (E) of the elevator is defined as,
E = mgy
Where m is the mass of the elevator, g is the acceleration due to gravity of earth and y is the height of the elevator from the earth.
The potential energy of the elevator at the top will be maximum since y is maximum at the top and at the ground will be zero since y is zero at the ground. The loss of potential energy of the elevator descends from the top of a building to a stop at the ground floor used in the mechanical work of the elevator when it comes from top to ground.
 
In case of any difficulty, please feel free to ask again
