PS
When I was a kid doing O level Physics taught by a guy callled Pete Best, he tried to explain to us that they would hit the floor at the same time. He used Chalk (not golf balls) and a filck of the wrist (not a cannon and a dropsy). to the naked eye, they did not hit the ground at the same time. He then told us he was in "Talking Heads" and left just before they became famous. Does that help ???? |

He wasn't even the best drummer in Talking Heads.

taking air resistence into account and assuming a flat planet I think in theory the fired golfball would land before the dropped one.
The net vertical effects of air resistance will be the same as for the dropped golfball, but the horizontal effect would mean it wouldn't travel as far and would spend less time in the air than if there was no air resistance. |

I must have gone to a more prosperous school. We had a little contraption that flung a ballbearing across the sports hall whilst dropping another at the same time. You could tell they landed at the simultaneously because there was only a single noise as they first bounced.

Couldn't have had that large a budget if they didn't have Orioles clones.

By:
Orioles clones mmmmmmmmmmmmmmmmm.
|
|
By:
We did that same experiment by the way (not the cloning stuff).
We didn't used ball bearings though, we used kitchen serving staff. Same time. Every time. Then a week of buffets. |

By:
you were wrong orioles, simple as that.
|
|
By:
A searing rebuttal.
Explain it in terms of the physics of the problem. It would take someone with an A at A level about 3 minutes. |
|
By:
changed my mind again, I think the air resistance effect is neutral :(

Drop of a Bullet
If air friction is neglected, then the drop of a bullet fired horizontally can be treated as an ordinary horizontal trajectory. The air friction is significant, so this is an idealization. From your link orioles THE EIFFEL TOWER AND THE SURROUNDING AREA IS NOT A VACUUM. IF YOU REALLY WANT FORMULAE, I WILL NEED MORE THAN 3 MINUTES, BECAUSE I AM QUITE P.ISSED. |

The question is, as suggested, a school standard 'You won't believe this but...' way of illustrating the effects of gravity. That doesn't however, demerit the efforts of people looking at it in real world terms - there are many other factors involved, some simple, like the curve of the earth, some far more complicated and requiring ballistics knowledge that I certainly don't understand. At the end of the day, it's just a question of who's been the biggest and most patronising tw@t, which until now, hasn't,for once, been me :-)

Sparky:
he's p.issed me off. i know that is often his aim on these threads. but he is clearly wrong and he insulted me by accusing me of being a liar regarding my a-level qualifications. which i realise is v. pretentious of me bla bla bla, but he really fked me off. but he is clearly wrong and gave a link to something which clearly said his argument did not apply in the real world and he did nothing to try and counter this argument when i raised the point. I don't like the guy. simple as that. |

There speaks a physicist ... and c&p from my own link!
Go to bed. Let's at least see how long it would take. Acceleration due to gravity is a constant. The first person to explore this was Galileo Galilei in the The Falling Bodies Experiment. Although it is disputed as historical fact, it is widely believed he dropped two objects from the Leaning Tower of Pisa to prove his theory. The Eiffel Tower is 300.65m high, how long before the BALLS hit the ground? To solve this problem, it is necessary to know that the gravity of the earth accelerates objects at a rate of 9.8 meters per second squared and then use the laws of gravitation formulated by Isaac Newton (1642-1727). The distance that an object travels under constant acceleration is given by the formula: distance = 1/2 |

Rob, you should know being wrong has never been an obstacle for Orioles! In terms of who is right, IMO see above - in terms of answering the question accurately, you are, and you made it clear from the start that's what you meant - in terms of answering the question in the, rather basic level of understanding, terms it is traditionally intended, his answer is right.
If he'd just accepted the real answer was a bit more complicated rather than trying to batter people over the head with a 1930s O level textbook, he'd have come out of this rather better. I do note that your initial post was rather insulting to him, but as he'd already insulted all and sundry, including those who were attempting a more informed answer to the question than he had proferred, he does in this case tick my 'you're the tw@t' box. |

Relax, RD.
You're a Planck, I admit it. |

Damn, that hurts. You can never have too many top physicists on your team :( |

Or college janitors! This is getting serious. |

He might not be a planck, you're just gaussing in my opinion.

two objects were dropped? you're not even attempting to disprove my theory there. i wouldn't even need to google that sh.it. i know all that stuff off by heart, not pretending to be clever or anything, i just do.
you've proved absolutely fk all there orioles. |

You're good with words, and good luck to you. Wish I was :( |

I wasn't trying to. I take it we can add an A in English at A Level to your qualifications? You haven't expressed a single, recognisable theoretical point beyond air resistance and even that was left unexplored! As I keep repeating, someone with your supposed academic achievements would rattle off the answer, but alas it's all hot air and whining. I appear to be better informed than you, and I last took a Physics exam in 1981! |

God, I hope you're happy, Munch Man! Look at what you've caused - grown men throwing insults at each other over an internet forum; the worst kind of libelling.
As a consequence of your actions, I would now like to resign as a member of The Munch Bunch...actually, I'm only joking. Please let me stay, pleeeeeeeeeease! Well, at least until after the Paris field trip anyway. We can even swing by here while we're there: http://www.paris-golf.com/english/index.htm |

What did I do when I was bored BEFORE the Chit Chat forum?

By:
Yes, we shall dine at Le Belvédère and have Oriole's liver with some fava beans and a nice chianti.

Surely that's where it identifies Castlemaine XXXX as a lager, mate. |

:D
I liked that one, Spark. |

By:
It will be delicious.
Like me, somewhat unctuous, but tasty. |
|
By:
In the book, of course, he enjoyed the delicacy with an amarone, not a chianti.

I normally expect onions with my liver, but I'm not sure if they're available much in France are they?

I think this idea may be the only way RD and I will ever share a dining table :)

And even then you'd both be flicking peas of the end of the table whilst simultaneously dropping them.
