๐งพ Table of Contents Overview
Here are the main chapters and concepts covered in the book:
✅ 1. Measurement and Units
This section introduces the basic tools of physics. Topics include:
- SI units and systems of measurement
- Dimensional analysis
- Significant figures and errors in measurement
Understanding units and measurements is the foundation for all physical problem-solving.
✅ 2. Mechanics (Motion, Force, and Energy)
Mechanics is the heart of classical physics. It includes:
- Kinematics: motion in one and two dimensions
- Newton’s laws of motion
- Work, energy, and power
- Conservation laws: momentum and energy
The author uses intuitive diagrams and real-world analogies to explain how objects move and interact.
✅ 3. Heat and Thermodynamics
This chapter covers thermal energy and the laws that govern it:
- Temperature and heat transfer
- Specific heat capacity and latent heat
- Thermodynamic systems
- The laws of thermodynamics
It's particularly useful for understanding engines, refrigerators, and natural phenomena.
✅ 4. Electricity and Magnetism
A critical part of physics that explains how electrical systems and magnetic fields behave:
- Electric charge, current, and voltage
- Ohm’s Law and circuit analysis
- Magnetic fields and electromagnetic induction
- Applications in motors, transformers, and electronics
The topics are introduced with clarity, making them ideal for beginners in electrical science.
✅ 5. Light and Optics
This chapter covers the wave and ray nature of light:
- Reflection and refraction
- Lenses and mirrors
- Optical instruments
- Wave theory and interference
Great for students preparing for entrance exams and anyone interested in how vision and photography work.
✅ 6. Sound and Waves
Understanding sound helps in fields like music, engineering, and medical imaging:
- Nature and properties of waves
- Speed, frequency, and wavelength
- Resonance and Doppler effect
This part also links wave physics to practical applications such as sonar and ultrasound.
✅ 7. Basic Nuclear Physics
A brief yet powerful introduction to the world of atoms and nuclei:
- Structure of the atom
- Radioactivity: alpha, beta, and gamma decay
- Nuclear energy and fission/fusion
- Applications in medicine and energy
The explanations avoid excessive mathematics while still giving a solid conceptual understanding.
๐จ๐ Target Audience
“Basic Physics Principles and Concepts” is ideal for:
