Anyone a parachute expert?
 
Hi!
I'm testing parachutes for physical science project, and I just wanna know why the velocity of the falling parachute decreases the longer the strings, that the weight is attached to, get.
Why exactely is this?
Thanx! All help appreciate!:)

Anyone???
 
No parachute experts out there? Or what?

What exactly is what? Can you please specify what you need?

He NTK
 
He needs to know why the longer the strings on the parachute, the bigger the velocity

No, the smaller the velocity.

Is it because the canopy of the parachute expands, since the longer strings don't pull the canopy edges as close together as the shorter strings? Or is there another reason?
What if you tied ONE SINGLE string to the four strings that are attached to the four edges of the canopy, and tie the weight to that single string. The distance between the parachute canopy and the weight would be greater. Does the velocity decrease then (why?)?

Good Question
 
Maybe you should try that "tie one string" idea and see what happens. Then tell us the results. It may help us to understand and think of the answer.

Hi i'am new here
so you wana know why the farther away the payload the slower it goes?
well consider it answered becouse the payload blocks a lot of surface area when it as nearer and make the parachute like a half elipse and not a circle![EMAIL="michaelkitange@yahoo.com"]michaelkitange@yahoo.com:) :rolleyes: [/EMAIL]
