What's the highest an object has ever bounced?

Right, but as I said before, when it reaches “almost terminal velocity” depends on your standard of “almost”.

Isn’t there a theory that a big meteorite impact on Mars can send Martian rock ‘bouncing’ up, up, up to Earth and thereby provide clues to bacteria on the Martian surface?

I don’t believe Madoff kited a single check. You do that you don’t get to be Madoff.

That’s certainly happened (as well as similar impacts transporting material between other planets), but it’s debatable whether it should be called a “bounce”. Most of the ejected material comes from the planet, after all, not from the asteroid. One might as well say that a rock bounces when you spelunk it into a pond, because the water splashes up.

We can avoid that by saying when it reaches or exceeds it, which happens multiple times when TV varies.

The following is above my pay grade so please be gentle in your criticisms.

…“it doesn’t quite reach terminal velocity” is a reasonable definition as in Newton’s equations are good enough for government work (e.g., getting to the moon).

But “it reaches terminal velocity” is the definition of quantum reality or at least our current best understanding just as Einstein’s theory has supplanted Newton’s.

JTA: Isn’t that why the arrow reaches its target and the hare catches and passes the tortoise?

OK, but that time is unpredictable and essentially random, since the phenomena which cause TV to vary are random.

No argument.

Yeah, it’s “close enough for government work”.

My point was simply that you’re absolutely correct on theory, and even in practice, for many cases. But in practice there are many cases where we can say without silly qualifications that TV is reached, such as when I drop a badminton shuttlecock from 100 feet on a sunny day.

You’re a scientist; I’m an engineer. You have to be correct, I just have to make things work. :slight_smile:

If you ask me if a badminton shuttle is at TV after falling 100 feet, I’ll tell you “Yes, for all practical purposes”. If you ask me whether it is at TV after falling an inch, I’ll tell you “No”. But if you ask me where in the middle my answer changes, then I’ll have to grill you for more information on the qualifications.

Our legends tell of a young ball much like yourself who bounced 3 meters in the air. Then he bounced 1.8 meters. Then… he bounced 4 meters.

Do I make myself clear?
