Physics is the scientific study of matter, energy, motion, and the fundamental laws governing the physical universe. It seeks to explain how forces act, how energy transforms, and how natural phenomena operate across scales ranging from subatomic particles to astronomical systems.
From classical mechanics to modern physics, this field provides the foundational principles that describe how the physical world behaves.
Core Areas of Physics
