1. Introduction to Physics

  • Physics is the study of matter, energy, and their interactions.

  • It helps us understand natural phenomena and develop technology.

  • Branches include mechanics, heat, light, electricity, and magnetism.

  • Importance of physics in daily life, science, and engineering.


2. Measurement

  • Measurement is the comparison of a quantity with a standard unit.

  • Physical quantities include length, mass, time, temperature, etc.

  • Use of SI units (metre, kilogram, second).

  • Measuring instruments: ruler, stopwatch, balance, thermometer.

  • Concept of accuracy, precision, and errors.


3. States of Matter

  • Matter is anything that has mass and occupies space.

  • States of matter: solid, liquid, gas.

  • Particle nature of matter.

  • Changes of state: melting, freezing, evaporation, condensation.

  • Differences between physical and chemical changes.


4. Force

  • A force is a push or pull.

  • Effects of force: change in shape, speed, direction, or rest.

  • Types of forces: gravitational, frictional, magnetic.

  • Contact and non-contact forces.

  • Introduction to balanced and unbalanced forces.
