a goal keeper saves the ball and the goal shooter shoots the ball
The goal keeper defends the ball from being in the goal.
If a defender passes the ball with his feet to the goal keeper, the goal keeper may not touch the ball with their hands.
Yes
Yes.
Offside status is measured by the second last opponent (and a few other things). The goal keeper is an opponent. In your description, the goal keeper becomes the second last opponent. This occurred recently in the FIFA World Cup 2010 opening match of South Africa vs. Mexico. The SA goal keeper stepped up to punch at the ball, causing the Mexican attacker to be in an offside position.
If the ball completely crosses the goal line, between the goal posts and under the cross bar, during active play then a goal is awarded. This is true even if the goal keeper is holding or touching the ball at the time.
most of the time when a goal keeper takes the penalty shot but sometimes when the goal keeper of the other team is so much above his field or area the goal keeper may kick the ball from goal to the other goal.
No. Only in the penalty area may the goal keeper handle the ball.
The answer is yes, netball does have a goal keeper, the goal keeper is up the other end to the end that you are shooting and they have to protect the net and not let the opposition get the ball into the net.
So that it can stop the ball from going into the goal.
As long as the ball is inside their penalty area a goal keeper may handle the ball. The position of the ball is important. The position of the goal keeper is not.
