The branch of science that studies the interaction of matter and energy is called physics. This discipline encompasses various subfields, including mechanics, thermodynamics, and electromagnetism, which analyze how matter and energy interact in different contexts. The laws derived from physics govern notions like force, motion, and energy transformation, laying the groundwork for understanding various natural phenomena. By examining these interactions, physicists aim to uncover the underlying principles of the universe, contributing to advances in technology, engineering, and environmental science.
