"Negative PE converts to positive KE." - Phil Bouchard.
Illogical idiot alert!

Oh, Androcles, surely you can't be so stupid as to think you've laid
an artful trap.
Well, maybe for a buffoon like Phil, yes, but if you really believe
this is a fundamental problem with the law of conservation of energy,
then it's time to get the rust-brush out again.
(But you and I know that you're just playing little games for the
purposes of heckling.)

There is nothing wrong with that because the total mechanical energy
will be conserved. KE will keep increasing but PE will decrease
negatively thus canceling each other.

Oh look, we are playing Jeopardy!

How did mechanical energy get into the conversation?

Illogical idiot alert!
