Flashcard Questions and Answers

Physics

The study of matter, energy, motion, and the laws that govern them.

Origin of "Physics"

From Greek "physis" meaning nature.

Main Goal of Physics

To understand how the universe behaves through laws and principles.

Branches of Physics

Includes Classical, Modern, Nuclear, Quantum, and Astrophysics.

Classical Physics

Deals with motion, forces, energy, and waves — based on Newton's laws.

Modern Physics

Focuses on concepts like relativity and quantum mechanics.

Nuclear Physics

Studies atomic nuclei and nuclear energy.

Quantum Physics

Explores behavior of particles at atomic and subatomic levels.

Astrophysics

Applies physics to study stars, galaxies, and the universe.

Measurement in Physics

Accurate measurement is key to physics. Units are in SI (International System).

Force

A push or pull that can change motion.

Energy

The ability to do work — exists in many forms like kinetic, potential, thermal, etc.

Laws of Motion

Formulated by Newton — explain how objects move and interact.

Importance of Physics

Forms the foundation for technology, engineering, and understanding nature.

Physics in Daily Life

Used in vehicles, electricity, machines, satellites, phones, and more.

What is Physics?

Physics is the study of matter, energy, and how they interact.

Name three branches of Physics.

Classical Physics, Quantum Physics, and Astrophysics.

What is the main purpose of Physics?
