I have many questions that I haven't been able to find answers for on the internet, which is why I love these forums. I keep asking questions and thus far they have all been answered, thanks. I am a very curious person. One thing I never understood was the relationship between revolution and gravity. I understand that anything with mass inevitably exerts a gravitational pull on something else. However, on Earth if you take a globe and you put a toy human on it attached to a spring, and then you spin the globe, the spring would stretch out and the toy humans distance from the surface of the globe would increase(centrifugal force, moving out away from the center of the globe). I have always heard that the Earth's rotation increases its gravity. I don't understand that, would logically deduce that it decreases the gravity because the spinning Earth is trying to fling people off at the same time its mass induced gravity would try to keep people on. A little help on this one because it quite confuses me. Thanks.
