alright i will say this again. we all once thought that there was a force called centrifugal. i read your nasa thing and this is what i have to say.
Centrifugal force- a force pulling out away from the center of a spinning object parallel to the string holding a spinning rock.
now if you spin that rock around and cut the string. centrifugal force says that it will travel in a trajectory directly away from the center. you can try this at home. it wont work.
when you cut the string the object follows a trajectory which is tangent to the circle it is spinning in. or at a 90 degree angle to the string. in order for you to sling a rock at someone directly in front of you you have to release it when it is perpendicular to the line between you and him.
yes
force has a definition, but that does not mean it exists.
I hope to god you understand.

ok i get it.
if you put larger tires on a car you dont get any more grip because while you have mroe rubber, the weight is spread out across the whole thing. so with smaller tires have more grip per square inch. got it.
