The potential energy of the object is not the same on earth and moon because of varying acceleration due to gravity.
The given parameters;
The potential energy of the object on earth is calculated as follows;
P.E = mgh
P.E = 5 x 9.8 x 2
P.E = 98 J
The potential energy of the object on moon is calculated as follows;
P.E = 5 x 1.6 x 2
P.E = 16 J
Thus, we can conclude that the potential energy of the object is not the same on earth and moon because of varying acceleration due to gravity.
