The lines are part of the soccer field when the ball is in play. We know that the Laws of the Game require that a ball cross wholly over the touch line to be in touch (out of play), or wholly over the goal line within the goal to be a goal (fouls or other infractions of the Laws of the Game aside).
The lines on a soccer field mark different sides and positions within the field. These are made with a chalk or with a paint.
The lines that mark a soccer field are touch lines, goal lines, the halfway line, the center circle, corner arcs, goal area lines, penalty area lines, and penalty arcs.
The touch lines.
If the ball hits the line it's a FAIR BALL
There are a number of lines on a soccer field. None of them are called boundary lines. The touch lines run up and down the length. They form the sides. The goal lines are across the ends of the field. The touch lines and goal lines define the field's perimeter or its boundary. And a ball that is in play must wholely cross one of these lines (either on the ground or in the air) to be considered out of play.
Also known as the end line, the goal line is the line that runs the width of the field. It runs across the front of the goal and when the ball passes the end line within the goal posts, a goal is scored. If the ball passes the end line outside of the goal posts, the ball is out of bounds. Depending on who touched it last, a corner kick or goal kick will restart play.
yards all da way
The field in part (a) is stronger than the field in part (b) because it has a higher intensity or concentration of the field lines.
The lines that mark a soccer field are touch lines, goal lines, the halfway line, the center circle, corner arcs, goal area lines, penalty area lines, and penalty arcs.
Soccer goal posts must not be more than 5 in (12 cm) and must be the same as the width of the lines on the field.
In soccer, "pitch" refers to the playing field where the game is held. It is a grass or artificial surface where players compete during a match. The pitch is typically rectangular in shape and marked with lines for different areas of play.
Magnetic field lines are closest together at the poles of a magnet, where the magnetic field is strongest. This is where the magnetic force is most concentrated.
