Ive been wondering how frisbee's move around since like 3 hours ago, and here's my take:
frisbees move specially only becuase of air, i.e. they don't fly as well in a vacuum.
but as to how they move, this is what i think. the firsbee spins, so everywhere near the frisbee there is lower air pressure (one of bernoulis laws i think. or something like that). however there is lower pressure all around it so all the forces sort of negate each other and it just floats with little air resistance because of that. (therefore the initial push pushes it better all the way throughout). the fact that its curved i believe will trap some air there, (the lower pressure will keep the air coming there, essentially a pillow of air). that's why they float...
is any of this right? or is it all some drivel i concocted?
thanks for the help
oh and there's something similar in it to a gyroscope - that's why they don't tilt as much.
