If you want to learn physics from scratch, here are some steps you can follow to get started:
Build a foundation in mathematics: Physics heavily relies on mathematical concepts and tools. Start by developing a solid understanding of algebra, trigonometry, and calculus. These mathematical skills will be essential for solving physics problems and understanding the underlying principles.
Select introductory textbooks or online resources: Look for beginner-friendly physics textbooks or online resources that provide a comprehensive introduction to the subject. Some popular options for beginners include "Physics for Scientists and Engineers" by Serway and Jewett, "Fundamentals of Physics" by Halliday, Resnick, and Walker, or online courses from platforms like Khan Academy or Coursera.
Start with classical mechanics: Classical mechanics is the branch of physics that deals with the motion of objects, forces, and energy. It serves as the foundation for understanding more advanced concepts. Begin by studying topics such as motion, Newton's laws of motion, energy, momentum, and gravitation. These topics will provide you with a solid starting point.
Seek interactive learning opportunities: To enhance your understanding, engage in hands-on activities and experiments. Participate in physics demonstrations, join physics clubs or societies, and perform simple experiments to observe and verify the concepts you learn.
Practice problem-solving: Physics is best learned by solving problems. Work through practice questions and exercises provided in textbooks or online resources. This will help you apply the principles you learn and strengthen your problem-solving skills.
Seek additional resources: If you find a specific topic challenging or want to explore further, seek additional resources such as video lectures, online forums, or physics tutoring. These resources can provide alternative explanations and help clarify any difficulties you may encounter.
Progress to other branches of physics: Once you have a solid understanding of classical mechanics, you can start exploring other branches of physics such as electromagnetism, thermodynamics, optics, quantum mechanics, and relativity. These branches build upon the foundation of classical mechanics and introduce new concepts and principles.
Remember that learning physics requires patience and persistence. It's essential to break down complex concepts into smaller, manageable parts and continuously review and reinforce your understanding. Don't hesitate to ask questions and seek clarification whenever needed.
