There is NO WAY you can get an A level in Physics and not know the correct answer to this question. It's a basic principle that a child should understand, before moving onto potty training and solid food.

You're not sitting in your own filth, are you?

I didn't take Physics at A Level (and neither did you, dearie) but I did get an A at O Level.

This really is a completely straightforward, standard question. The use of pub 'black belt' logic to introduce a variety of variables is daft.

There has to be a site somewhere on google with this chaps the point I am making is that the golf ball will end up falling at its terminal velovicy.

If it is already fired at its terminal velocity horizontally it will maintain a constant speed throughout its descent but the vetical compment of its velocity will increase and the horizonal decrease.

I dont think if you include air resitance that the vertical component of of the two balls increase at te same rate.

To be 100% Iwould like to do the math

Surely if one of the balls were dropped off of one side of the Tower in Pisa and the other ball the opposite side, surely one would hit the ground before the other? ;)

You weren't hit on the head by a golf ball while visiting the Eiffel tower on your magic carpet were you, RD?

Same time.

On the other hand a ton of coal is heavier than a ton of feathers.
(Best illustrated by having the scales in a swimming pool, follow same logic for air).

Common misconceptions about guns:

A dropped bullet will hit the ground before one which is fired from a gun.

As shown in the illustration of a horizontal launch, gravity acts the same way on both bullets, giving them the same downward acceleration and making them strike the ground at the same time if the bullet is fired horizontally over level ground.

Ori, are you saying that if I held a gun in one hand and a bullet in the other and then fired the gun horizontally and dropped the bullet simultaneously, they'd both land at the same time?

orioles is living in a vacuum with no air resistance. that is the problem nestor. He's good at talking, as we all know, but he hasn't actually combatted the argument that honest (more eloquently than me, admittedly) has put across.

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.

Fair enough, rob. I must admit it does sound difficult to believe, but I dropped all science subjects at school, as soon as was feasibly possible.

Everyone on this thread is a dunce.

The top of the Eiffel Tower is very narrow. The base is very wide.

Therefore it is impossible to drop a golf ball vertically without it making contact with the tower on the way down. Possibly even getting stuck.

Stick your physics.

You can only examine what happens without (as I mentioned earlier) introducing variables to defeat the scientific principles.

If you introduce those variables, then the chap who suggested that if the golf ball achieved escape velocity, the dropped ball would hit the ground first, would be as correct as anyone else.

This is the sort of question anybody who has studied physics would answer immediately. They hit the ground at the same time. It's barely above a quiz question.

You've been caught **ting, RD. Best leave it.

Thank you very much for your answers. Now tell me this: presuming the golf balls landed on the same type of surface, would their second touchdowns land at the same time as well?

This question would have beena lot more visually exciting, without in any way interfering with the basic principles involved, if it had been one frenchman having a dump, and the other one having a violent 90 degree widdle.

Firstly, I only deal in golf balls and not bodily functions. And secondly, the principles only apply to objects of equal size and weight.

I don't think that's true, actually (again, negating resistance etc). Feathers fall at same rate as cannon balls etc.

wrong ... but the experiment can only be conducted accurately in a vacuum (no, not a hoover), so you would have to extract all of the air from the Paris region ... a task not beyond the collective ingenuity of the ChitChat Forum imo

Gus has it.

To be fair to RD, I think that's what he was on about.

How dare you tell me I'm wrong! How do you know what my principles are?
