Hi. I'm doing a project on alternative fuels for my Science class, and since I'm in 8th grade, I really don't know much about them. I know what they are used for, but are they easy to obtain?

Was this a pure cultural (non-physical) evolution?
Was there physical need for it (in the brain) for our survival?
Was it just an evolutionary byproduct that is harmless thus it stays?
Or, do you have any other theory?

What forces apply on diffrent parts of a roller coaster?
I know that GPE, EK, Friction, Air resistance, Normal apply on almost every part of the roller coaster, but if I want to be exact:

1) What other force applies on a roller coaster model?
2) Explain a bit more about the force of .... I don't know what it's called, but I think it has something to do with the turning around a "center" in the loops.
