Sports balls can be grouped based on properties like size, color, texture, and bounce. For instance, balls used in games like tennis and cricket may be grouped together based on their smaller size compared to larger balls used in football and basketball. They can also be categorized by color, such as white cricket balls or yellow tennis balls, and by texture, such as the smooth surface of a basketball versus the stitched surface of a baseball.
