Physics & Chemistry Fundamentals refer to the basic principles and concepts that form the foundation of physics and chemistry. In physics, this includes laws of motion, energy, force, and matter. In chemistry, it covers atomic structure, chemical reactions, bonding, and the periodic table. Understanding these fundamentals is essential for exploring advanced topics, solving scientific problems, and appreciating how the physical world operates at both macroscopic and microscopic levels.

What are Newton's laws of motion and why are they important?
Newton's laws describe how objects move: (1) inertia resists changes in motion, (2) F = ma, force causes acceleration, and (3) every action has an equal and opposite reaction. They explain everyday motion and engineering principles.
What is energy and what are its main forms?
Energy is the ability to do work. Key forms include kinetic (motion), potential (position), thermal, chemical, and electrical energy; energy can transform between forms, while total energy in a closed system remains constant.
What is atomic structure?
Atoms have a nucleus containing protons and neutrons, surrounded by electrons in orbitals. The nucleus is positively charged, electrons determine chemical behavior, and the arrangement of electrons defines an element's properties.
What are chemical bonds and chemical reactions?
Bonds (covalent, ionic, metallic) hold atoms together to form molecules. Chemical reactions rearrange atoms to create new substances, with mass conserved and energy changing as bonds break and form.
