In mathematics a falling object never reaches the ground I wonder who came up with this c**k and bull?

Answer 1

For example, the Moon.

Answer 2

Sounds like you're talking about Zeno's Paradox, which in terms of falling objects would translate to "An object falls out of the sky and reaches the point where it's half a mile from earth, then a quarter of a mile from earth, then an eighth of a mile, then one sixteenth of a mile from earth, and so on. These measurements go on to infinity, therefore the object never reaches the ground."

Now obviously, we know in real life that a falling object is eventually going to land. We can look at Zeno's paradox and say, "Well that's stupid." But seriously: why, exactly, is it stupid? How do you pinpoint the flaw in the argument? If logic can really explain what we see in the world, then why is this argument "wrong"? It just goes to show you that when you try to introduce infinity into things, you can get contradictions.

Answer 3

That old argument is wrong--the one that says that you just keep getting half as close in half as much time. The series of the sum of the time periods does converge to an actual number. So mathematics will confirm that the falling object DOES reach the ground.

Answer 4

A falling object never hits ground because at the molecular level, the electrons repel each other and never touch. I don't know who was the first to think of that.

Answer 5

It was Newton and is based on the theory that if you fire a cannon ball from a mountain and the ball reaches a speed such that the curved Earth's surface falls away beneath it and it never reaches the ground.

Answer 6

well, in theory its not bull, as this can be achieved by saying that athe falling object falls half the distance as it did in the last 'fall', hence if it started off 100m above, ground, it will fall 50m, then 25m, then 12.5m, it will never reach 0. similarly you can also see this happening in half life in radioactivity as only half of the sample randomly decays, and then half of that sample that was left from last decay decays etc etc etc, so it never reaches 0.
this is theory, not junk and bull.

Answer 7

Because the Moon is also moving in its orbit; although it aims at the ground, it also moves around so it won't get any closer. It it stopped moving orbitally, it would hit the Earth, quite quickly! That's why satellites hit the ground eventually - air friction slows them down.

Answer 8

Hi. You can't divide up an infinite number of points into a finite equation. Just drop a rock on your toe to prove that!

Answer 9

Yes. LIke the arrow never reaching the runing man,too! Cods!

Answer 10

It goes in slow mo like the 6 million dollar man. (That would be the 6 trillion dollar man at todays prices)
