Physics is a fundamental branch of science that studies matter, energy, and the interactions between them. It explores the laws that govern the universe, from the smallest subatomic particles to the vastness of space.

Key areas of physics include:

• Classical Mechanics – The study of motion, forces, and energy, based on Newton’s laws.
• Thermodynamics – The study of heat, energy transfer, and work.
• Electromagnetism – The study of electric and magnetic fields and their interactions.
• Quantum Mechanics – The study of particles at the atomic and subatomic levels.
• Relativity – Einstein’s theories explaining space, time, and gravity.
