In a football game, when they ran the ball and the ball carrier gained four yards on the first down,it means that they only have to gain 6 more yards in the next 3 tries. The team has four tries to gain ten yards.
no it is defined as follows: player is down when knee or above, or forearm or elbow is cleary on the ground.
It is spotted at the point where the ball is when the knee hits the ground.
No ... if the shoulder, elbow, forearm, or wrist touch the ground the ball carrier is also considered down.
Not in the NFLNope. At least not in the NFL. If a ball carrier falls down on top of an opposing player and does not otherwise touch the ground, he is not considered down by contact and may continue to advance the ball.Some part of the ball carrier's body, other than his hands or feet, has to make contact with the ground for him to be considered down(Technically, a knee or elbow or helmet has to make contact with the turf for the carrier to be down).This is true for all levels of football play: HS, NCAA, NFL.
By one of four ways: 1. His/her flag is pulled 2. He/she runs out of bounds 3. Depending on the league you play in but i believe that if he/she drops the ball (fumbles) the play is dead and the ball carrier is down. 4. He/she knee hits the ground they are deemed "stopped" (also depending on the league)
A defender can legally yank on a ball carrier's hair to bring him down. The hair is considered part of the player's uniform.
In both Rugby Union and Rugby League, an illegal (or more properly termed "dangerous") tackle is penalised by a penalty kick.Examples of illegal/dangerous tackles include:- tackling the ball-carrier while they are in mid-air- high tackle (above the shoulders)- "spear" tackle (where the ball-carrier is lifted into the air and thrown down on their neck or head)- "charging" (where the tackler makes no effort to grapple the ball-carrier but simply hurls their body at them)- kicking, striking or tripping the ball-carrier (although in Rugby League, where the tackler and ball-carrier are in close contact and stationary, the tackler can trap the ball-carrier's feet with his own to effect the tackle, provided this is not done dangerously*)- tackling the ball-carrier either before or after they have the ballAt the referee's discretion, a player committing an illegal or dangerous tackle may be cautioned by the use of a yellow card which is also usually accompanied by the player being suspended from play for 10 minutes. A second yellow card will be followed by a red card and the player being sent off the field for the rest of the match.In cases of particular danger to players' personal safety, the offending tackler may be sent off immediately for a first offence.The full code of laws for Rugby Union and Rugby League respectively in England may be found at:http://www.irblaws.com/downloads/EN/law_10_en.pdfhttp://www.widnesrlreferees.btik.com/attachments/rugby_laws_book_2004_%5B1%5D.pdf* For those who have knowledge of Judo, examples of "safe" throws would be e.g. kosoto gari or kouchi gari, since in these the tackled player falls directly to the floor on their back, and under control. Examples of potentially dangerous throws include osoto-gari, o goshi, tomoe nage, ippon-seoi-nage, or indeed most loin/hip/shoulder throws, since the tackled player is likely to be thrown in mid-air and land on their shoulders. Experienced players may be able to manage subtle hip or loin throws, but at risk of being penalised for dangerous play.
If you drop a ball in sand, the sand particles will absorb some of the ball's kinetic energy, causing the ball to slow down faster than if it were dropped on a hard surface. The ball will also create an indentation in the sand as it lands, displacing some of the grains.
Offensive players cannot tackle anyone(they can block or run down the defensive players if they're the ball carrier) unless during the play, there's change of possession(examples: interceptions, fumble recovery), any offensive player can tackle the defensive ball carrier.
Real Difference for example: In all United States High Schools; if football is played, tackle football is played by men, and flag football is played by girls or for fun. In tackle football, the ball carrier needs to be taken to the ground by a tackle. The knee needs to hit the ground, by getting hit to the ground. In touch football, or in the many variations such as one-touch and two-touch, you merely need to touch the ball carrier for him to be "down". In flag football, players wear flags, usually attached to the waist by Velcro. The tackler must pull off the ball carrier's flag thing for him to be "down."
In college football, once a player's knee touches the ground the play is whistled dead regardless of whether a defensive player made contact with the ball carrier. In the NFL, a defensive player must make contact with the ball carrier to have the play whistled dead. So to answer your question, in college the player is down and the play is over. In the NFL, the player is not down and the play continues.
