Principle of Lift

[Jimmy89]

Hello everyone,

I've been asked "What is the principle of lift". I've been told by some people that the wing gets pushed up and other ones tell me that the wing is getting sucked up :confused: I've found some information on the site but I do not really understand such scientific language (I'm a 14 yo who hasn't started Physics yet). If someone can provide me with a link which explains the theory in simplified form or tell me what is the principle of lift and how it happens I'd be greatly appreciated. Thanks a lot guys in advance

Jimmy,

There's loads of interesting stuff on this site:

Also, if you're planning to do physics up to your equivalent of (UK)A-levels (sorry i don't really know how the system works down there!) then this site is a simple but very useful resource:
http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html

hope that helps!
