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.
There is no such thing as an "ormal curve". And a Normal curve IS symmetrical!
A curve is so strong because when you apply a force on top of the curve the weight of that forced is transferred to the bottom parts of the curve which makes it really strong like bridges that use arcs
yes
they curve because they have a heavy filling inisde that makes it curve
It has to do with the way somthing spins so if you hold side it will curve

A curve
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 projectile makes a curved path known as a parabolic curve when launched horizontally or at an angle. This curve is a result of the combined effects of gravity and the horizontal velocity of the projectile.
I think the earth is wobbling on its axis and it makes the tracking lines appear to curve when they are laid over the map.
Your question makes no sense. Significant is a word related to tests. The normal curve is a distribution, not a test.
