The ball isn't thrown at the start of a football game. The game begins with a kick off. After the kick off the only time a ball can be thrown by an out field player is if it goes off at the sideline and a team is awarded a throw-in.
When the ball is kicked out on the sideline (or Touchline), the procedure is the team who did not touch it last, gets to throw the ball in from the sidelines by drawing the ball behind their head with both hands and while both feet are planted on the ground and throw the ball back into play.
Gravity is the force that makes a thrown ball fall back to the ground. It pulls objects towards the center of the Earth.
If the ball was thrown-in by a teammate, no. If the ball was thrown-in by an opponent, yes.
Naturally the ball in space will travel the longest distance as long as it does not bump into something along the way. Gravity on earth will cause the ball thrown to fall back to earth.
Gravity is the force that gives a thrown ball its vertical movement. As the ball is thrown upwards, gravity acts on it, pulling it back down towards the ground. The vertical movement of the ball is a result of the interaction between the force of the throw and the force of gravity.
When a ball is thrown upward, it experiences a brief period of acceleration while moving against the force of gravity. Once the ball reaches its peak height, it begins to fall back down due to gravity.
the ball has gone out so it will be a sideline pass, to the other team. if you cant see clearly who it came off it will be a toss up.
The speed of the ball is greatest when it is thrown upward and decreases as it reaches the peak of its trajectory. The speed continues to decrease as the ball falls back down due to the force of gravity pulling it towards the ground.
The ball has gone "in touch" and the restart is a throw-in.
Depending on which team kicked it out of bounds, the other team sends one of their players to throw the ball back in to play towards one of their own teammates.
If the line judge is able to tell exactly where the ball crossed the plane of the sideline, then he will immediately go to that spot on the sideline. Otherwise, the line judge will begin walking back toward the line of scrimmage with his hand raised, and the referee (who would have watched the play from behind the punter) will stop him at the point where the ball crossed the plane.
