What Happened To The Concorde?

[po2wq]

Why was the coin travelling at super sonic speed.

Let's assume, if you are tavelling on a open top car with the same speed as the concord, will the coin still travel?

What I do not understand is, what cause the coin to travel since it has no engine to propel it?

wen a vehicle accelerates, it oso accelerates evryting inside/connected 2 it ... datz y u feel ur body pushes against ur seat wen a vehicle accelerates ... in other words, ur seat pushes u 2 mov 4ward n gain speed ...

wen ze vehicle den cruises @ constant speed, dose same items r thus travelling @ ze same speed as ze vehicle ... hence, ze coin inside ur pocket has ze same speed as u n ze vehicle ...

if ze vehicle is travelling @ constant speed, wen u throw a coin, ze coin wud drop directly downwards ... if it is not @ constant speed, depending on acceleration or deceleration, ze coin wil land otherwise accordingly ...

From the science theroy and everyday observation, that is very true.

However, I am trying to find a very "simple" answer, to explain why is the coin moving when it is not attaching to anything but air in the vehical?

In this case, coin is very much heavier then the air.

In an enclosed carriage, the air inside the enclosure is travelling at the same speed as the carriage. Wind down the window to let the air flow and see what happens. Your hair and clothes are also threatening stay behind even if it's not windy outside at all.

The coin's path will not be vertical. It will lose some sideway velocity because of inertia.

You remember the stage trick where the magician/acrobat pulls the table cloth clean off the table while the plates/cups/cutlery remain in position? That's inertia at work.

Inertia from wikipedia.

In common usage, however, people may also use the term "inertia" to refer to an object's "amount of resistance to change in velocity" (which is quantified by its mass), or sometimes to its momentum, depending on the context (e.g. "this object has a lot of inertia"). The term "inertia" is more properly understood as shorthand for "the principle of inertia" as described by Newton in his First Law of Motion. This law, expressed simply, says that an object that is not subject to any net external force moves at a constant velocity. In even simpler terms, inertia means that an object will always continue moving at its current speed and in its current direction until some force causes its speed or direction to change. This would include an object that is not in motion (velocity = zero), which will remain at rest until some force causes it to move.

On the surface of the Earth the nature of inertia is often masked by the effects of friction, which generally tends to decrease the speed of moving objects (commonly to the point of rest), and by the acceleration due to gravity. The effects of these two forces misled classical theorists such as Aristotle, who believed that objects would move only as long as force was being applied to them.[2]


Ok, in the last sentence, I was misled that objects would move only as long as force was being applied to them.

So, it's one of those mysterious working of nature that you know it works but you can not completely explain it, like gravity and magnetism.

Ok, thank you very much for all your inputs.

So, instead of tossing the coin by the flick of the finger, let say you hurl the coin up in the air with the full force of your hand traveling upwards by 20 metres, will the coin still travel forward at 80 kmph?

at the moment it left your hand it move forward at the same speed as your vehicle but if you can toss it so high you have to factor other elements in like wind resistance etc.

ok, one example if you jump up in the air or a helicopter hovering at the same spot while the earth is still spinning why these objects won't move west against earth spinning which is to the east, the answer is because the the momentum of earth spinning that throw the object in the same direction at the same speed

the wing of supersonic plane is different from subsonic plane.

subsonic plane wing are thick and contour, and tilt slightly 5 degree, so the cabin is level.

supersonic plane wing are thin and flat, to achieve lift, the whole plane have to tilt slightly.

maybe the tilt is too small and your visual have adjusted to it, but supersonic plane have to tilt.
That is for sure.

Ok none of you feel it. fine, too small angle i guess.

I never flew it, cause i am cheap, refuse to pay for such a ride, but when it is ending, i was too busy working, no time to go.

I dun know where u get your info from, but its ridiculous. There is no real basic difference between the wings of subsonic and supersonic planes. There is no such things as thickness, tilt, etc. Jetliners today are subsonic because that is the most fuel efficient way to fly, and the wings are designed to be efficient for maximum fuel economy. The concorde's wing is a delta wing, which happens to be a better wing for supersonic flight. But not all delta winged planes are supersonic. For example, the A-4 Skyhawk has a delta wing, but is not a supersonic plane.

All planes can fly level, even suprersonic planes. Its a question of how you trim the plane. Many times when u feel a plane is flying tilted, it usually is in a gradual climb to its flight level.
