What is the difference between relativity and special relativity, and how do they relate to each other?

Relativity is a theory that describes how objects and energy interact in the universe, while special relativity is a specific branch of relativity that deals with the behavior of objects moving at high speeds. Special relativity is a subset of the broader theory of relativity, focusing on the effects of motion on space and time. Both theories are interconnected, with special relativity providing a more detailed understanding of certain aspects of relativity.
