Step-by-step explanation:
Potential energy is defined as the energy present within an object due to its position.
Mathematically, P.E = mgh
where, m = mass of object
g = acceleration due to gravity
h = height of the object
Therefore, when a picture hanging on a wall then it is placed at a definite position from where it is not moving. Hence, the energy possessed by it will be potential energy.
Therefore, we can conclude that a picture hanging on a wall has potential energy.
