Re: Problem



Several people have been discussing d|v|/dt and whether it represents
something connected to acceleration. I am unaware of any such defined
connection. Has there ever been any official declaration that d|v|/dt means
anything, i.e. have physicists ever officially attached any name to it?

I like the question posed by someone earlier, which I'll expand here... If
v at the top is zero, and if a is zero or undefined, how does it get back
down? Or a similar question... which of the following would you like to
choose: (1) gravity turned off for an instant (i.e. no force present at the
top), (2) Newton's second law quit working for an instant (the force on the
object due to being in a gravitational field momentarily did not cause any
acceleration)?
