Branches of Physics Quiz

Branches of Physics

• Mechanics: Study of motion, forces, and energy
• Thermodynamics: Study of heat, temperature, and energy transfer
• Electromagnetism: Study of electricity, magnetism, and electromagnetic waves
• Optics: Study of light, its properties, and behavior
• Quantum Mechanics: Study of behavior of matter and energy at atomic and subatomic level
• Relativity: Study of space and time, including special and general relativity

Key Concepts

• Space and Time: Three dimensions of space (length, width, height) and one dimension of time
• Matter and Energy: Two fundamental forms of physical existence, convertible into each other
• Forces: Pushes or pulls that cause objects to change motion or shape
• Energy: Ability to do work, comes in various forms (kinetic, potential, thermal, etc.)
• Motion: Change in position of an object over time, described by velocity and acceleration

Laws of Physics

• Newton's Laws:
  1. Inertia: Objects at rest stay at rest, objects in motion stay in motion
  2. Force and Acceleration: Force is equal to mass times acceleration
  3. Action and Reaction: Every action has an equal and opposite reaction
• Law of Universal Gravitation: Every point mass attracts every other point mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them
• Conservation Laws: Laws that state that certain physical quantities remain constant over time, such as energy, momentum, and angular momentum

Important Physicists

• Isaac Newton (1643-1727): Developed laws of motion and universal gravitation
• Albert Einstein (1879-1955): Developed theory of relativity and famous equation E=mc²
• Marie Curie (1867-1934): Discovered radioactivity and first woman to win a Nobel Prize
• Galileo Galilei (1564-1642): Pioneered use of telescopes and challenged geocentric model
