A slider is similar to a curve ball in the fact that it breaks from left to right or right to left depending on if your a righty or lefty, but the ball doesn't break downward like a curveball does.
When a fast ball and curve ball are mixed together it is called a slider.

A breaking ball is a general term for any pitch that breaks or curves, while a slider is a specific type of breaking ball that moves horizontally with sharp, late movement.
To the batter the slider properly thrown has the batter thinking he is facing a fastball. This among other things fools the batter and he is not expecting the ball to waver in its flight to home plate. I filled in part of the discussion area to explore this pitch in more depth.
A fast ball is when the pitchers throws the ball straight at the strike zone, it doesn't curve (curve ball) or lower (slider), it goes straight ahead.

A curveball falls under the general category of "breaking ball". A "breaking ball" refers to any pitch that is thrown with movement (i.e. a curveball, slider, sinker, etc.").
Both the slider and the breaking ball are effective pitches in baseball, but the effectiveness of each can vary depending on the pitcher's skill and the situation in the game. The slider is known for its sharp, late-breaking movement, making it difficult for batters to make solid contact. On the other hand, the breaking ball, which includes pitches like curveballs and knuckleballs, can also be effective in fooling batters with its unpredictable trajectory. Ultimately, the effectiveness of each pitch depends on the pitcher's ability to control and execute them effectively.
