why is this on the wishlist???

they shouldn't.
the denser one would have a high terminal velocity...i don't think (just a guess) they would explode on impact, but comparing low flashpoint avgas to jet fuel isn't a convincing argument.  i do remember reading somewhere about pilots dropping full tanks & having the guy behind them light them with 0.50 cal.  theat 2nd guy would not be needed if the tanks behaved like a ford pinto

Go visit some of the Museums in the Normandy area.  I was amazed at how many had 'dropped" DTs in their collections.  Some flattened, lots dented but overall intact.

And to be honest, worrying about making DT's explode in AH would I hope be way down the list of priorities for HTC

Weren't drop tanks made of heavy duty paper? If it's punched off an aircraft and hits the ground... I don't know what would be there to actually cause a spark and get ignition. So, that sort of nixes using them as incindiary bombs.

Make a puddle and lighting it with APIs or something... okay, but uh.. what's the practical use of it in the MA?

A falling body accelerates uniformly: it picks up equal amounts of speed in equal time intervals, so that, if it falls from rest, it is moving twice as fast after two seconds as it was moving after one second, and moving three times as fast after three seconds as it was after one second.

In other words, a heavier object accelerates faster than a lighter object.

Somebody either failed physics or should have.

Kind of falls under the same category as which weighs more... A pound of iron or a pound of feathers?

Some were paper tanks, others were metal.

Well if you actually looked at my first post, you would see my hint on... humm lets see... drop tanks that do damage instead of hitting ground and not doing anything yet it prob should...


And NHawk ive been leaving out information (normal me i forget to do alota stuff) the reason "heavier objects" accelerate faster than "light objects" it because there is more gravity acting on that object than the lighter object because its mass is greater,  and im passing physics thank you very much.

it seems all of you are a little off on the physics:D

weight doesnt effect falling speed, surface area does. if you drop a tank that's full and one that isnt, the both still have the same surface area, and therefore fall at the same rate. you drop a steel ball and a feather on earth, it takes the feather far longer to hit the ground. however, in a vacuum, or, as they tested, on the moon, both hit the ground at the same time...

acceleration on earth is 9.81 m/s2, no matter what the weight of the object is. therefore the only thing that can change is air resistance, which is governed by surface area for a given volume. hope that clears it up a bit:aok

[Nemeth]

WOW pooface where did u go to school?
where does surface area fit into the gravity part of physics??
its the mass and strength of gravity that determine the acceleration. and yes we all kno that the gravitational force at earths surface is 9.8m/s/s

So pooface GO BACK TO SCHOOL AND RE-LEARN PHYSICS!

How many people have to tell you you're wrong, before you take a hint?

[Brenjen]

Well in AHII drop tanks do explode when hitting the ground & they leave marks like a rocket or bomb impact, I don't know if they do or do not cause damage though.

 As far as what falls faster, I think the point pooface is making is that, say you take an aircrafts wings - you smash one in a compactor until it is a perfect square - the other you leave in the shape of a wing. If you were to drop thes two objects, both of which weigh exactly the same ammount & made of the same material...given enough distance of travel the square is going to impact first. The wing will have more drag & fall slower than the cube. Also the wing is likely to land somewhere other than straight below where it was released from. The drag is why & the surface area is responsible for the drag.

 You can do the expirament with a sheet of paper too, wad up one in a tight ball & leave one in loose sheet form and drop them from a highrise.

Acceleration is always a constant, therefore the only thing that can change that will effect the speed of an object as it falls is air resistance. Air resistance is directly proportional to surface area.

now then, we have two droptanks, both the same size, same surface area, except one has more fuel in it than the other, making it heavier. you drop them, they will fall at the SAME rate.

GET IT YET????

talk about relearning physics, you need to tell your physics teacher that he's doing it wrong tomorrow at school mate

typing it big makes you right:noid

This quote is NOT funny.

These two paragraphs are related how?

Nemeth, I'm under the impression that you are still learning physics.  I know what you think may make sense to you, but please read what others have said.  Then read your books again.


Damnit!!!
WARNING:
From now on, no complete thoughts will form, just brainstorming outloud:

Nemeth may have something here about density.
Earth has a constant gravity.
I weight more on earth than on the moon.
Moon's gravity must be weaker.
Moons gravity must be less.  Slower acceleration than the earth's gravity.

I'm thinking the moon will fall faster to earth than I will.  Earth must find the moon to be more sexier than I.  It's attracted to it more.

2 drop tanks underwater.
1 is filled with water.  The other is filled with hellium.  Which will fall faster to the sea floor?

2 drop tanks in the air.
1 is filled with fuel.  The other is filled with air.  Which will fall faster to the ground?

It's got something to do with density.  I'm almost there.  I can feel it!

Does the air pressure in the empty tank equalize from the original high altitude that it was dropped from to the denser air near the ground?

In a vacuum, we have 2 drop tanks.
1 is filled with air, and the other is filled with fuel.
Which will hit the ground first?  In a vaccuum?  Hmmm.. They both hit at same time?  Can this be right?

So gravity in space (vaccuum) and gravity in some kind of medium (air) and density (more mass to produce greater gravity).

What the f does this all mean?

<-----------waits patiently for someone to respond.  I can't go to sleep now.  Damnit.

Wow, this discussion reminds me of the old "if a tree falls in the woods and lands on a mime, does anyone care?" joke.
