Please help.....

When something is thrown over a large distance (on earth ) what new factor comes into play?
1- The decrease in gravity over long distance
2- The increase in gravity over long distance
3- The tendency of thrown objects to fall to the ground
4- The difference between mikes and kilometers
5- The curvature of the earth

  1. I guess an intercontinental ballistic rocket is something "thrown over a large distance (on earth)"
    so
