I'm finished now, physics was my last one yesterday. But I'm incredibly bored, WTF DO I DO NOW???!!! Srsly what is there to do?

Spend time with your friends?
Game?
Sport?

Don't think being on ATAR Notes would be what I would be doing if I was finished....
Notice how empty the forum is at the moment :P

FREEDOM!!!

Did my last one today, now to get another job for the summer.

I don't finish for another 21 hours... but I have felt like I have been done for the last week. A 7 day wait between my second last subject and my final subject and I've spent 3 hours a day watching the news and reading political literature as my form of 'study' (But I'd be doing it anyway) and watching youtube videos apart from that... I even started searching for a job cos I felt like I had so much free time... Cannot wait until 2:00 tomorrow!

Freedom is still so far away - Last session of all, 23rd.

Already feel finished, I'm exhausted.

Actually you have 362 days, 11 hours and 24 mins since you have physics last same as me  :P

STOP COMPLAINING. I HAVE ANOTHER 365 DAYS UNTIL FREEDOM !!!!!!!!!! :'(

Sucks for you I guess...dw though, the year will fly by like a bird in the sky soaring way up high at the speed of pi...m/s (why didn't I do lit?) :)

Quick question.... is 3.14 m/s for a bird practical?
Title: Re: FREEDOM
Post by: Greatness on November 16, 2011, 09:44:07 pm
It may seem like the end of year 12 will take ages to come but trust me when yuo get there you will be like 'wow that went fast.....' then you will wish you studied more or went out more etc
So enjoy the holidays!! Dont over do it!

I'd say it is fairly practical. Some men can run 100 meters in less than 10 seconds, which would mean 10 m/s... which would mean that the bird is going one third as fast as the very fast runner.

Just by thinking about it, I reckon a bird could travel at one third of the speed of an Olympic runner.

3.14m/s=3.14*1000/3600=11.30km/h
The slowest moving bird apparanetly has been clocked at 5 mph = 5*1.61= 8.05km/h http://wiki.answers.com/Q/What_is_the_slowest_bird_in_the_world, http://en.wikipedia.org/wiki/American_woodcock
So it can happen, but not for all birds.
Remember that lift increases with the square of velocity so at low speeds, only a small amount of lift can be generated to counter-act the weight force, so only smaller/lighter birds would be able to fly at this speed. But it is possible. Lets call this "plausible" (out of confirmed, plausible and busted).

Nice thought processes going on right here!... so I guess my poem rhymes and makes sense!

Man, I was thinking about maximum speed rather than minimum speed :P

But it is possible. Lets call this "plausible" (out of confirmed, plausible and busted).

Also, there's nothing to say that the bird didn't start flying, then slow down to such a speed that lift exactly equalled the force of gravity pulling it to the ground, leaving it flying at the slowest speed it could possibly go at. Assuming it was at least a few meters off the ground it could probably do this quite safely.

Likewise, sometimes birds take advantage of those rising columns of hot air that hang gliders use in order to fly. I would imagine a bird could take advantage of these to fly quite slowly (they appear to hardly move when they are flying in them sometimes)

EDIT: Come to think of it, I remember seeing birds hovering as they ate the nectar from flowers on a documentary once. Surely their speed would be close to zero as they 'flew'...

It's probably going to have a hard time finding that exact speed since if it is flapping it's wings, the forces are not constant but irregular and cyclic, if its gliding, it may find this speed for an instant but it will still encounter some air resistance, so it will slow down past this speed.

Yeh the hot columns of air would work, kinda similar to if the bird had a head wind of the exact speed to keep it in the air, then try to get the forces in equilibrium in a gliding position (now that I think about it, thats probably what you meant above). It's relativer airspeed would be different to it's actual airspeed, and so it's airspeed compared to the ground could be 0 m/s but compared to the air, 3.141592653589.... m/s.

EDIT: Geez we really are bored, we are talking about the aerodynamics of birds.

Lol, so much for freedom. We will never be free from the inflicted scars education has left upon our minds. We will forever be consumed with mathematical problems of no real world application. Exhibit A, the friggen bird  ;D


Not quite finished yet but feels like it. OMG french, hurry the fack up.
