The question is sort of confusing, I will answer the best way I can: you can inbound the ball and pass it to someone backcourt, even though you had already crossed midcourt. So for example: if the defense fouls you (not a shooting foul), your team keeps possession, when you inbound the ball, you can pass it to a player that is backcourt and it won't be a violation. Hope this helped.
If it hits the other team and goes back, then no. However if it hit your own team mate and goes back court, then yes.
There are many violations of basketball. You can not move with the ball when you are not dribbling. That is called a travel. The only exception is when you take two steps for a layup. You can not dribble the ball, pick it up, and then dribble again. That is called a double dribble. If you are on offense, you can not stay in the key for longer then 3 seconds or else you will get a 3 seconds call. You have 5 seconds to throw the ball in when it is out of bounds. If you don't get the ball inbounds in time it will be a turnover. You have 10 seconds to get the ball down the court onto the opposite half to which the ball was thrown in. If you don't get it across halfcourt on time that will be a turnover. These are just a few of the many violations.
No. College football only requires a player to be in possession of the ball and have one foot inbounds.
It is an inbounds violation resulting in a turn-over.
If you're in possession of the ball, and your foot or any other part of your body makes contact with the floor outside of the court, it's considered an out. If you jump outside of the boundary and toss the ball back inbounds before you make contact, it's not out.
Yes. But (perversely) you cannot return inbounds to catch a pass.
No, but can be affirmative.
Yes. The technical way to score a touchdown is to have to ball "cross the plane" into the endzone without the player being down or out of bounds. With a catch, the player must establish himself as inbounds while maintaining possession. In the NFL, the player must do so with two feet inbounds. In NCAA Division I football, the player only needs to do so with one foot inbounds. With a run, the player must have not stepped out of bounds before the ball crosses the plane into he endzone.
If his knee touches inbounds, he is considered tackled in the field of play, regardless if the the ball ends up out of bounds. The clock will continue to run
