The word "ball" is a general term used to describe a spherical object. The scientific name would depend on the specific type of ball you're talking about. For example:

* A ball of yarn: This would depend on the type of yarn. Wool, cotton, etc., each have their own scientific classifications.

* A basketball: Technically, the scientific name would be "basketball." However, it's a common name, not a formal scientific one.

* A ball of fire: This is a colloquial term and doesn't have a scientific classification. It might relate to a phenomenon like a meteor or a burning object.
