When a pitcher throws a curve ball he grips the ball with his fingers to impart spin on the ball when he thows it toward the batter. This gives the ball two motions i.e. forword velocity and spin. If the spin axis is in the vertical plane (i.e. updown )the pitch will rise if it is spining clockwise (i.e. toward batter) and fall if counterclockwise(i.e. away from the batter). If the spin is in the horizontal plane clockwise spin will(i.e. toward the batter)the ball will cause the ball to move toward the 3rd base side of the batter. If the spin is clockwise (i.e away from the batter) the ball will move toward the 1st base side of the batter. The reason for the ball movement is the air is moving over one side of the ball faster then the other causing lift or a aerodynamic force in the direction of movement. This force is caused by the spin on the ball. Think about the air on one side as moving at the speed of ball forward velocity plus the spin velocity and the other side as moving at ball forword velocity less the spin velocity. Various grips, arm positions, release points will then make the ball look like it is a dancing curve.

What are the physics behind a curveball?

Not entirely sure what a curveball is, but the physics behind it is quite simple. When a pitcher throws the ball, it goes straight, but gravity is also pulling it down. Since it is goiig forward, it creates a downward curve. To make it go left or right, just position yourself on the opposite side of the position you choose.

What science is in baseball?

physics, physics, physics. the laws of phisics are extremly importent in base ball. when you throw a baseball, the outward force , of your hand, propels the ball at a tremendous speed, if you you're a good pitcher. a curve ball is all science. in a curve ball, the pitcher throws a ball in such a way to spin the ball like a top. this spinning causes increased friction with the air on one side and reduced friction on the other. the increased friction also causes increased pressure. the pressurizzed air wants to go the lower pressure on the other side, which forces the ball to the left or right

What does He was behind the curve ball on that one mean?

It means that someone has mixed up three different expressions. One is "to be put behind the eight ball," which is an allusion to the game of pool, meaning to be placed in an awkward, difficult or untenable position. The second expression is to "throw someone a curve ball," which is an allusion to the game of baseball, meaning to suddenly introduce unexpected difficulties for someone. Third is to be "behind the curve," an allusion to graphs, meaning not at the leading edge of things, out of it, slow or stupid. As to what the sentence is TRYING to mean, that's anyone's guess. Maybe its intended meaning is He really dropped the ball that time, or He messed up hugely there.

Why do left-handed pitchers ball curve?

If a southpaw is pitching the ball will curve slightly more because everyone has a muscle that is stronger in their left arm than right. The ball won't curve on it's own, it is probably a curve, slider, or spitball (illegal).

How far behind the home plate is the strike zone?

A pitched ball is ruled either a ball or strike based on whether or not it has passed over home plate. Extend the surface of home plate upwards, and that is the zone through which the ball must pass. If a pitched ball does not pass over home plate, but is still caught directly behind home plate (curve ball) it is a ball.

Where do you hit the soccer ball at to curve it?

To curve it right to left, hit the ball with the inside of your foot on the bottom right hand side of the ball. To curve the ball left to right, hit the ball with the outside of your foot, on the bottom left of the ball. Yes that's correct,but if you want more power hit it with the tip of your foot.
