I need to do a Gr. 11 Physics project and I really want to do it on skiing. Any ideas of what i should do like aerodynamics, airtime?? Any help would be great.

you should do it on railslides.....show how you have to keep your weight centered, and how you need enough speed to clear the rail, and how the faster you go the easier it is to balance....shit like that

like quadratic functions and parabolas and shit? we did that shit back in tenth grade

THE SPRINKLER: get butt naked and then do a 1260 while taking a piss, i expect this trick to win many comps this coming season.
 
umm, thats math...

'Don't be a pussy Waldie. It is impossible to get hurt on this jump' my words to Steven Waldie just before he hit the jump and broke his coller bone.
 
do it on the dynamics of dropping a cliff. how the initial velocity, acceleration due to gravity, height of the cliff and all that good stuff affects how long it takes before you hit the ground. that would be easy and effective

'Well... You.. Look pretty easy and you might put out, so roll in the cream cheese, roll in the cream cheese!'
 
how far r u in phisics i took it last year and am in ap phisics now. i would say either trajectory or the acceleration due to the slope of the mountain

Alcohol the cause and solution to all lifes problems.
 
physics is math, that's why i hate it

ohh, i didnt take physics this year cuz all i need is the highst math to get into what i want for CJEP...

I've done kinematics, dynamics, all that acceleration stuff, relativity, stuff like f=ma, net force, normal force tons of that.. and just starting stuff with 'work and energy'...

I'll assume Gr.11 is grade 11, but we dont call em grades where im from so youll have to be more specific about what sort of level your physics is at. An easy one would be to figure out where you will land (ie air time and distance travelled height attained) given velosity of the skier and the angle of the take off, you will have to assume that the skier does not pop at the top of the jump. you could also consider where the skier should begin their run in from - assume its real icey adn there is no friction if you want to make it easier. if you are a real eager beaver you could even do some table design and figure out what angle take of is best for the right combination of height and distance. or.. you could explain why high tables are scarier to do becoase you have to go much faster in to them to get up the ramp and still have enough speed to jump but are more forgiving as the landing ramp is much longer so its harder to miss and land on the flats at the bottom -

 
If you want to get really into it, I'd suggest a book called, 'The Physics of Skiing, Skiing at the Triple Point.' It's by David Lind and Scott P. Sanders. It's a textbook for a physics elective that they used to teach at CU-Boulder. It's good if you have some physics background to read it, but you can understand it with very little knowledge.

They talk about how a ski slides on snow, how a ski actually works, and then they go into the mechanics of traversing and turning. It's an intersting read if you like physics anyways.
