What makes a baseball curve?

Answer 1

The rotation of a thrown Baseball, or any other ball, compounded by the stitching on a ball, creates lift/drag as it moves through the air, accomplishing each type of pitch- fastball, curve ball, change-up, etc. As an aside, the "knuckleball" is thrown with as little rotation as possible, which causes the more erratic movement as it passes through the air towards home plate.

Answer 2

It is due to air pressure and the spinning of the ball combined with its forward movement, both together causing a pressure difference on opposite sides of the ball, causing the ball to "break". Airplane wings lift an a plane in a related manner.

Answer 3

Becouse when people through the balls they might not throw it correctly or the wind might make them curve

Answer 4

i curves because of the spin you put on it when it leaves your hands.

Answer 5

Bernulli's principal, the same formula that makes airplane wings push up, pushes a curve down.

Answer 6

The friction of the seams with the air causes the ball to curve

Answer 7

the snap of the wrist when thrown is a forward flick and causes the forward rotation to make the ball drop dramatically

Answer 8

The spin of the baseball.
