Bernoulli’s Principle Experiments With Paper Planes

December 16th, 2009CTPressure

Do you like the idea of having a plane all by yourselves.

Well, after this Cool Science Experiments For Kids YOU CAN…!!!

In fact, this a very simple experiment.

All you need is: 2 PIECE OF A4 PAPER…!!! and a pair of scissors

Hey kids, save a tree, save the earth, just find some used A4 paper. OK…

By now. I think most of you know how to fold a paper plane.

But, if you still in doubt below are the step by step guide. Just fold along the dashed line(s).

You will need two paper plane for this experiments
Plane 1 : Step 1 - Step 5
Plane 2 : Step 1 - Step 6 (Kids, please take note. I have make some modification on our plane)

Step 1 : Fold along the dashed lines, then open it out	Step 2 : Just fold along dashed lines and follow the arrows.
Step 3 : Keep following the dashed llines and arrows	Step 4 : Just follow dashed line and arrow again ;P
Step 5 : You know what to do...	Step 6 : There is a slight modification here, cut along the red lines

Judgement Day…!!!
Just fly your 2 private jets. Have a lot of fun.

What happen ? :-

Notice that:-

Yeah...We Are Go Up...!!!

Flight path of Plane 1 keep flying down.

But, flight path of Plane 2 was up and down. This shows that how Bernoulli Principle works when a plane taking off.

Explainations:-

Side View Of Your Plane

Bernoulli Principle Revisited

From the side view of your plane, you notice that the top surface is slightly curve upwards, while the bottom is flat. So when you fly your plane through the air, the air flow speed on top has to travel faster to cover a longer distance. The air flow below the wing is slower.

Remember to what Mr. Bernoulli said, “a steady flow of fluid (gas or liquid), the pressure of the fluid decrease when the velocity(speed) if the fluid increase”

Ah…forget it!!!

In the case of your plane, the air flow on top of the wing is faster, therefore creating a lower pressure region on top of the wing. While the slower air flow under the wing creates an higher pressure region. Thus, the higher pressure helps the plane to take off or flying upwards.

For more flying actions…!!!


Flights of nearly 300 feet are possible…!!! Kids, 300 feets…!!!	A bit hard on taking off. But, you can go 500 feets with the plane…!!!	The Dark Force…!!!

The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge.

If God is perfect and if ID is a viable theory and counterpoint to evolution, then how did God create a complex and faulty organism called man? Does this mean God is faulty, or did I not get enought sleep yesterday?

I have been reading your posts for the last few hours, and it all has been very informative and well written. I did want to tell you that for some reason this entry doesn’t seem to work in Internet Explorer. On a side note, I was wondering if you wanted to swap blogroll links? My website is Router Table Plans if you’re interested. I hope to hear from you soon!

Thank you for a very clear and helpful post. I am definitely a violator of many of these rules. I often find myself conflicted when writing a blog post because I see myself writing more than people want to read, but I feel that I have to do the subject matter justice by thoroughly covering it. I feel that by following some of these rules I end up cutting out important aspects to the discussion. I guess you have to find a balance.
