Re: [Phys-l] Student Misconceptions

I'll take a stab at this.

If the mass miraculously increases at the instant that the bob is at 
it's lowest point, then the amplitude will decrease.

If the mass miraculously increases when the bob is at it's highest 
point, then the amplitude will increase.

Am I missing something?  (except for maybe someone else's response - 
further down the mailbox?)
