Why is the gravitational potential energy of an object 1 meter above the moon's surface less then it's potential energy 1 meter above earth's surface?

the object's mass is less on the moon.
the object's weight is more on the moon.
the object's acceleration due to gravity is less on the moon.
both a and c.

First we have to define what mass and what weight is. Mass is simply the  amount of matter a certain object contains. Weight on the other hand involves the pull of gravity onto  the object. From the definition, mass is equal both in the moon and on earth. From that we can extrapolate the idea that The object's acceleration due to gravity is less on the moon. The third option is the answer. 

The correct answer is c. hope this
