Maybe they don't teach the basics of speed and velocity to idiots in modern high schools, but they aren't synonymous to non-idiots any more than someone like K-Dog would confuse amps and watts. 

Ergo....I knew EXACTLY what I said, and obviously revealed it by providing a directional component to that ball climbing a hill....

Quote from: RE2nd, absent any outside force besides Gravity, the ball travels straight up or down the hill, it doesn't spiral.

Good thing I provided a mental image of how it COULD work to negate your particular example, regardless of the how. And it is even a BETTER example than yours....because as an analogy it fits the history of doom proclamations that don't happen, yet everyone seems to think they are X time away...and then a decade after X time has passed, folks claim it all over again!

Thanks for not mentioning anything about how obvious this rinse, recycle and repeat cycle is. It means you know you don't have a way around the obvious history of doom. Be it from Catton, Ehrlich, or everyone in the modern internet age.

Quote from: REThird. the velocity increases due to the force of gravity accelerating it down the hill.

I wasn't discussing going down the hill. That is your interest, and the thing that hasn't happened (but HOPE abounds!). And all of those who came before you....the ball has reached the top of the hill....DOOM!!!  And then a decade later presto...rinse, recycle, repeat...how in the heck did Newtonian Mechanics get me back up the hill! Again!

Quote from: REYour understanding of Newtonian Mechanics is pathetic.

And your ability to counter the underlying thought of rinse, recycle and repeat is worse.

I've mentioned it before, your perspective has been around for a millennium. What is it they say about history? Learn some or be doomed to repeat it?

Newtonian Mechanics to combat a thought experiment....while avoiding the actual point. Which is factual, and therefore impossible to refute.
