Introduction to Physics

Physics

• Physics studies matter, its motion, behavior in space and time, and related concepts like energy and force.
• Key areas include:
  • Classical mechanics: Describes macroscopic object motion, including Newton's Laws.
  • Thermodynamics: Studies heat, work, and temperature relationships.
  • Electromagnetism: Explores electric & magnetic phenomena and their connections.
  • Optics: Focuses on light and its properties.
  • Quantum mechanics: Examines matter and energy at atomic and subatomic levels.
• Fundamental forces: Gravity, electromagnetism, weak force, and strong force.
• Key concepts:
  • Energy: Capacity for work.
  • Force: Push or pull that alters motion.
  • Momentum: Tendency for moving objects to continue in a given direction and speed.
  • Work: Energy transferred by a force on an object.
• Physics uses math models and equations to describe phenomena.

Chemistry

• Chemistry studies matter's composition, structure, properties, and reactions.
• Key branches:
  • Organic chemistry: Focuses on carbon-containing compounds.
  • Inorganic chemistry: Studies non-carbon-containing compounds.
  • Physical chemistry: Applies physics principles to chemistry.
  • Analytical chemistry: Develops methods to identify and quantify substances.
• Matter is made of atoms, elements' basic building blocks.
• Elements cannot be broken down chemically.
• Compounds form from multiple elements combined in fixed ratios.
• States of matter (solid, liquid, gas) differ in properties and behavior.
• Chemical reactions rearrange atoms to form new substances.
• Key concepts:
  • Atomic structure: Arrangement of protons, neutrons, and electrons.
  • Chemical bonding: Forces holding atoms together.
  • Chemical reactions: Processes transforming substances into different ones.
  • Stoichiometry: Quantitative relationships between reactants and products.
• Chemistry uses mathematical principles to predict chemical behavior.

Mathematics

• Mathematics studies abstract concepts like numbers, quantities, and relationships.
• Key branches:
  • Arithmetic: Basic number operations (addition, subtraction, multiplication, division).
  • Geometry: Focuses on shapes, sizes, and positions.
  • Algebra: Uses symbols to manipulate expressions.
  • Calculus: Studies continuous change (differential & integral calculus).
  • Statistics: Analyzes data to draw conclusions.
  • Probability: Examines likelihoods and patterns.
• Math principles apply to physics, chemistry, engineering, and more.
• Fundamental operations: Addition, subtraction, multiplication, division, exponentiation, logarithms, trigonometric functions.
• Key concepts:
  • Sets: Collections of objects with defined properties.
  • Functions: Associations between value sets.
  • Relations: Connections between sets.
  • Numbers: Natural numbers, integers, rational numbers, irrational numbers.
• Mathematics uses abstract notation and symbols to represent concepts.
