There is no requirement that the ball be removed, but it is considered good golf etiquette. As pointed out by one commentator, why deprive someone of that glorious sound of a ball hitting the bottom of the cup after all the hazards, mulligans and lost balls?
The potential energy gets less until the ball gets to the bottom of the hill, at which point the potential energy is zero. The potential energy that is lost, gets converted to Kinetic energy of the ball that goes faster and faster as it gets more and more of the Potential energy.
This is the case when you assume that air resistance is negligible - and that therefore, no mechanical energy gets lost during the falling of the ball.

Energy is lost in every cycle. "Lost" means simply that it is converted to some other kind of energy, such as heat or sound.
"had" is the past tense of the verb to "have" Thus - "I have a ball" "I lost my ball" "I had a ball until I lost it"

No, this is not allowed. The only way you could do this is if you lost your ball and had to play another. You may however change balls in between holes, as long as you alert your playing partners.
