Here's why it doesn't change:
* Singular Form: Even though it represents multiple items, "equipment" is treated as a singular noun.
* No Plural Form: There isn't a separate plural form like "equipments".
Example:
* "The company has a lot of equipment in its warehouse."
* "The gym is full of new equipment."
If you need to specify the quantity, you can use phrases like "a lot of equipment", "pieces of equipment", or "items of equipment".
