James and Juan were at the highest point in the football stadium, dropping water ballons on people below. Many of the ballons did not break, so the boys added more water to the ballons. What impact did adding water have on the ballons' potential ener
a) It had no impact; it just made the ballons bigger.
b) The gravitational potential energy decreased because the diameter increased.
c) The gravitational potential energy remained constant because they did not increase the height.
d) The gravitational potential energy increased because the mass increased.
