When can a football field goal be made?

Answer 1

A football field goal can be made whenever a team is close to their goal line and on 4th down. If they feel they are unable to complete a pass or run to make a 1st down they can attempt a field goal and take 3 points rather than 6 with a touchdown.

Answer 2

In football a field goal would be executed when it passes through the uprights of the goal post.
