No, it could ruin their arms in a few years and may not be able to pitch high school ball.
If he is skilled enough
Baseball.
Three things affect the trajectory of a curve ball: Coriolis effect, gravity and precession AKA spin drift.
it drops there because when you throw a slow ball it will dorp there too.also when you throw a curve,you put top spin on it and a curve is slow too and if you want to hit it you are goin to have to watch it all the way and then hit.
0% because they are horrible
It depends on the situation. You can throw a curve ball on the first pitch to get ahead but make sure you are hitting the corners and you don't make a habit of it because you will tip off hitters and they will set on the pitch. Also you can throw a curve ball when you are 0-2. If you have a good curve and a hard one you can attempt to throw it for a strike or if it's not that good you can throw it in the dirt and try to get the hitter to "fish" for it. If you throw it in the dirt and there is someone on base make sure you have a catcher who can lock it so there won't be a passed ball allowing the runner to advance to the next base.

Baseball is the only sport to have a technique officially called a 'curve ball'. However, the various forms of bowling, including bowls (aka lawn bowling) also sometimes refer to the hooking of the ball after its release as a curve.
A slider is thrown like a curve ball just much faster.
The word curve can be used as either a verb or a noun. As a verb: when you throw a ball, its path will curve downward, because of gravity. As a noun: the equation can be drawn on the graph as a smooth curve.
hold the ball like a four seam fastball then you know how you throw a curve get more grip and hold the ball tighter when your releseing the ball give it more break on it and curve your arm the other way then just relese it last with your index finger hope this helps. p.s it can hurt your hand
