Hi,

 

Does anyone know why the stomach makes that weird feeling when you drop down suddenly like on a rollercoaster. Any ideas?

My "guess" is that your stomach feels that way, because it gets pressed against the diaphragma above it. It has to do with physical forces which are active on a moving object ( don't ask me more about them though ).

In combination with Krul's note about physical forces, the stomach lining also contains "stretch receptors" which tell us when the stomach is distended. Perhaps the stomach's lining get stretched somehow during the motion, and this causes the receptors to fire in an unusual or erratic way, generating a "weird feeling".
