Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

The answer is false because: gravitational force is independent of medium and depends only on the masses of the two objects and the distance between them

The answer is sucrose.
