physics

Physics is the fundamental natural science that studies matter, energy, and the interactions between them. Its goal is to understand how the universe behaves, from the smallest subatomic particles to the largest galaxies, using precise observations and mathematical models.

The 10 Greatest Physicists in History

• Einstein: Relativity. • Newton: Gravity. • Maxwell: Electromagnetism. • Bohr: Atoms. • Feynman: Quantum theory. • Curie: Radiation. • Galileo: Telescope. • Planck: Quanta. • Dirac: Antimatter. • Faraday: Induction.

What Is Newton's First Law Of Motion?

Newton's first law of motion states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external net force. Also known as the law of inertia, it establishes that forces are required only to change an object's motion, not to maintain it.

What is Electricity?

Electricity is a form of energy resulting from the existence or movement of charged subatomic particles, primarily electrons. It is the invisible force that powers our modern world, functioning through the accumulation or flow of these charges.

Chemistry

Chemistry is the branch of science that studies the properties, composition, and structure of matter, alongside the changes it undergoes and the energy transformations involved.Often called the central science, it bridges the physical sciences with life sciences and applied disciplines.
