It's not a homework problem or something. But you've moved it here. I've searched about this subject for 10 days. But there is not much useful information about spinning of maple seeds. I've got the book Spinning Flight (Dynamics of Frisbees, Boomerangs, Samaras, and Skipping stones) but there...
I didn't find any useful information about this question from Google or Wikipedia. And, If I knew how to solve it I wouldn't discuss it here.
Unfortunately there isn't even one maple tree in where we live.
I would appreciate anyone who helps me to solve these problems.
Thnx.
I have some questions about Maple seeds:
1. Describe Maple seed spinning process.
2. Does the altitude influence the speed of seed when reaches floor?
3. Can we change the seed in a way that while it's spinning its speed also increase?
4. Some seeds are twins! They're connected together. Do they...
Here is a question I wish you to help me:

please help me to answer to this problem:
Problem: Imagine that we replace sun with a black-hole of same mass.
1. How would be movement of earth?
2. Does the atmosphere of Earth change? If yes, explain.
thnx
