If it does so above the crossbar and the last player to touch it was an attacker, then it's a goal kick. If it does so above the crossbar and the last player to touch it was a defender, then it's a corner kick. If it does so below the crossbar and it came directly from the defender's goal kick, corner kick, kickoff, or throw-in, it will be no-goal and a corner kick for the attackers If it does so below the crossbar and none of the above apply, a goal should be awarded and the restart is a kick-off for the defenders.
A goal is scored once the football has passed over the goal-line, and between the two uprights and crossbar. A goalkeeper is there to try to prevent the ball scoring a goal.
In association football, a goal is defined as follows: "A goal is scored when the whole of the ball passes over the goal line, between the goalposts and under the crossbar, provided that no infringement of the Laws of the Game has been committed previously by the team scoring the goal." If you are referring to the goal-posts, then the goal-posts are defined as follows: "A goal must be placed on the centre of each goal line. A goal consists of two upright posts equidistant from the corner flagposts and joined at the top by a horizontal crossbar. The goalposts and crossbar must be made of wood, metal or other approved material. They may be square, rectangular, round or elliptical in shape and must not be dangerous to players. The distance between the posts is 7.32 m (8 yds) and the distance from the lower edge of the crossbar to the ground is 2.44 m (8 ft). Both goalposts and the crossbar have the same width and depth, which do not exceed 12 cm (5 ins). The goal lines must be of the same width as the goalposts and the crossbar. Nets may be attached to the goals and the ground behind the goal, provided that they are properly supported and do not interfere with the goalkeeper. The goalposts and crossbars must be white." Both of these are quoted from the Laws of the Game.
Pipes Net and Crossbar
A goal is scored when the ball completely crosses the touch line, between the goal posts, and below the crossbar such that it was not propelled by the hand or did not enter by any other infraction of the laws of the game.

There are no rules governing the sizes for 5-a-side goals for adults. The most common size is 4 ft. high by 12 ft. wide. For children under 8 though the official size is 6 ft. high by 12 ft. wide.
In soccer, the "regulation" width of the goal is 8 yards, or 24 feet. A goal that is marked by posts alone, that is, a goal that lacks a crossbar, might be used in special circumstances. But it is clearly not an "official" structure and does not meet the minimum requirements set down in the Laws of the Game.
