Physics
Physics is the branch of science that studies the fundamental laws of nature, focusing on matter, energy, space, and time, and how they interact.
In simple terms:
Physics tries to answer questions like:
-
What is the universe made of?
-
How do objects move and interact?
-
What are forces like gravity and electromagnetism?
-
What is light?
-
How does time work?
Key Areas of Physics:
-
Classical Mechanics – motion of objects (from apples falling to planets orbiting)
-
Electromagnetism – electricity, magnetism, light
-
Thermodynamics – heat, temperature, energy transfer
-
Quantum Mechanics – behavior of atoms and particles at the smallest scales
-
Relativity – motion at high speeds and the nature of space and time (Einstein's theories)
-
Nuclear and Particle Physics – the smallest building blocks of matter
-
Astrophysics and Cosmology – stars, galaxies, black holes, and the origin of the universe
Why it matters:
Physics helps us understand everything from how your phone works to why stars shine. It's the foundation of engineering, technology, and many scientific fields.
