The penalty spot.
A free kick takes place from the spot where the foul occurred. If the foul happened outside the penalty area, the free kick is taken from that spot. If the foul occurred inside the penalty area, the free kick is taken from the nearest point on the penalty area line.
It is used during the taking of a penalty kick to ensure that all players except the kick taker and the goalkeeper are both outside of the penalty area and are at least 10 yards from the spot where the kick will be taken.
It is called the penalty arc. It is to ensure that defenders are 10 yards from the penalty spot when a penalty kick is taken.
Free kick distance is entirely dependent on where the foul occurs on the pitch. However, the penalty kick is taken from the penalty mark, which is a spot 12 yards (11 m) from the goal.
The main differences are that a penalty is only taken from the penalty spot inside the box, and a free kick is taken from where the offence took place, and can happen anywhere on the pitch unless it was a penalty. The opposition is allowed to put up a wall of players to defend the free kick, in a penalty it is only the penalty taker against the goalkeeper.
If the defending team commits a foul inside their box then it is deemed a penalty.
From the penalty kick point.
no a different player can't kick penalty after a penalty is recall.
When a player commits a foul in his own penalty area (the one surrounding the goal that he is protecting), such as pushing an opponent, a penalty kick is awarded to the attacking team, unless advantage is played. In some places, very young players do not use penalty kicks, such as U-8 games in the United States, and sometimes all free kicks are indirect.
The penalty spot or penalty mark.
A penalty kick is awarded when a defender commits a direct free kick offense, against an attacker, within his own penalty area, and during active play. The penalty kicker places the ball on the penalty mark, 12 yards from the goal, and gets a one-on-one kick against the opposing goal keeper. All other players must be outside of the penalty area, 10 yards from the ball, and behind the ball at the taking of the kick.
The D keeps players 10 yards from the Ball when a penalty kick is taken. Whenever a free kick is taken, the defending team must always be 10 yards away from the ball. This includes penalty kicks. The penalty spot is 12 yards from the goal line. The penalty area is 18 yards from the goal line. All players have to be outside of the box when the penalty kick is taken. Without the D, the players standing behind the penalty taker would only be 6 yards from the ball. So, from the penalty spot, a 10 yard radius is drawn and marked only outside the penalty box (so it ends up looking like a D)
