A diagram of a 12–6 curveball. In baseball and softball, the curveball is a type of pitch thrown with a characteristic grip and hand movement that imparts forward spin to the ball, causing it to dive as it approaches the plate. Varieties of curveball include the 12–6 curveball, power curveball, and the knuckle curve.
The two-seam fastball, the sinker, and the screwball, in differing degrees, move down and in towards a right-handed batter when thrown, or in the opposite manner of a curveball and a slider. The shuuto is often confused with the gyroball , perhaps because of an article by Will Carroll [ 4 ] that erroneously equated the two pitches.
Magnus effect on Roberto Carlos' infamous "banana kick" An animated diagram of a 12–6 curveball The Magnus effect explains commonly observed deviations from the typical trajectories or paths of spinning balls in sport , notably association football , table tennis , [ 27 ] tennis , [ 28 ] volleyball , golf , baseball , and cricket .
The eephus pitch is thrown overhand like most pitches, but is characterized by an unusual, high-arcing trajectory. [2] [3] The corresponding slow velocity bears more resemblance to a slow-pitch softball delivery than to a traditional baseball pitch. It is considered a trick pitch because, in comparison to normal baseball pitches, which run from ...
The concept of a "world line" is distinguished from concepts such as an "orbit" or a "trajectory" (e.g., a planet's orbit in space or the trajectory of a car on a road) by inclusion of the dimension time, and typically encompasses a large area of spacetime wherein paths which are straight perceptually are rendered as curves in spacetime to show ...
In Major League history, the term knuckle curve or knuckle curveball has been used to describe three entirely different pitches. All are unrelated to the similar sounding knuckleball . The first, more modern and commonly used pitch called the knuckle curve is really a standard curveball , thrown with one or more of the index or middle fingers bent.
