Simply so the batter, base runner and fielders know what the call is ...
in baseball a base coach would yell 'BACK' to a baserunner if the pitcher made a pickoff move to the base from which the baserunner had taken a lead.

A coach may yell out from the dugout but, it is up to which ever player has the ball when the play is over. All he has to do is touch the contested base with the ball in his hand. The umpire will either rule safe or out. It has to happen before another pitch is thrown.
Well what you could do is try to ignore him. If that doesnt work maybe try talking to him and say " Coach im having a hard time with you yelling at me, can you please try not to yell". Now if he doesnt stop i would talk to your mom. Now if you dont really like the sport try doing another. Thaat could be a problem you cant cure. Coach is yelling because you are not following his instructions. if you do as per his instructions ,he will appreciate you. hence you can get over his yelling.
Not ussually. I mean they do, they yell at the ref and bring them over to the bench and talk to them but I've never seen a coach win the arguement.
Get a stopwatch. Get a runner (or get runners). Determine and measure the distance between point A and point B. Start the runner(s) at point A. Yell "GO!" and start your stopwatch; the runner(s) should start running from point A toward point B when you yell "GO!" When the runner(s) reach(es) point B, click your stopwatch and see how much time elapsed. This would be the speed of the runner(s) from point A to point B. If you need to convert this to other distances or other measurements, you will have to perform mathematical calculations accordingly.
that's what my Pop Warner coach taught us many years ago
It could be signs that the coach is giving the batter or as a form of cheering or encouragement
The present tense of "yell" is "yells".
If you hear a coach or player yell "Service while the ball is being served it is just another way of saying the serve is coming over. It's to get the players attention and get their heads in the game. My coach says it all the time especially if we are not paying attention :)
Coaches yell at kids younger than that. My four year old is in t-ball and their coach yells. It's very inappropriate, but I'm sure you know how easy it is to lose it when kids are involved.
