Yes...and no. If a game goes into overtime play, it is extended by 30 minutes, played in two 15-minute periods. But the duration of "standard play" can be a little fuzzy.
During play, the clock runs continuously, regardless of any interruptions (ball out of bounds, injuries, etc). The referee keeps track of these interruption's, and at the end of the second half (two 45-minute halves in adult play), the referee continues the game to account for any interruptions. In some games, the referee will announce how much "stoppage time" he intends to add -- but ultimately, he's the sole arbiter and standard play ends when he says it does.
There isn't an official name, but it's often called added time or stoppage time.
Each official has different responsibilties. The Refere is the man who controls the game and his word is final. The two linesmen are to decide on offside decisions and they also have a big part in helping the refere making decisions. The 4th official is just there to to hold up a board which will either say the amount of stoppage time to be added on at the end of a half or the show who is coming off and on in substitutions.
The dimensions of an official soccer linesmen flag are 17" x 13" and the colors are traditionally red and yellow. In theory, the official is suppose to snap the flag up or down to make the call and the noise from that action alerts the field referees. Because soccer games can be quite noisy, linesmen carry noice devices as well as flags. I added a link to an example of an official linesmen flag.
Will get stronger. This is because there is more air in the same amount of space so this number will go up.
Women's football was added to the official Olympic programme in 1996. Women's football is gaining in popularity, though the strength, aggression and speed required in top class football make it a challenging game for women.
The standard is 3 when you open it, but more can be added, limited by the amount of memory in a computer.
About twenty are added each year.
Yes it is. In addition to the mens game, womens soccer was added to the Olympic program in 1996.
The additional time added to the end of each period of play, often called injury time or stoppage time, is the amount of time that the referee has determined needs to be added because of substitutions, assessment of injuries and removal of injured players, time wasting, and any other cause at the discretion of the referee.There is no standard amount of time that should or must be added for any particular event. A common belief is that 30 seconds are added for every substitution, but this is incorrect.Time is only added for events that are not natural in the course of play. Taking a few extra seconds to set up the perfect corner kick is perfectly natural, but waiting on a goal kick to run down the clock is not.
Arabic was added as an official languages in 1974.
At the end of each half (45 minutes) the referee decides how much time is to be added on due to injuries and stoppages, he tells this to the 4th official who indicates it by holding up a board.
The time added on at the end is known as injury time. It is the time that has been wasted when play was stopped for an injured player to get treatment.
