Physics delves into the nature of matter, energy, and their interactions through forces.

Classical Mechanics: Examines the motion of objects, encompassing kinematics (description of motion) and dynamics (forces causing motion). Newton's Laws of Motion govern this realm, defining forces, mass, and acceleration.
Thermodynamics: Focuses on energy transformations and transfers, governed by the laws of thermodynamics (conservation of energy, entropy increase in isolated systems). Heat transfer mechanisms include conduction, convection, and radiation, all influenced by temperature and thermal energy.
Electromagnetism: Explores the interplay of electric and magnetic fields. Key concepts include forces between charged particles and Maxwell's equations describing the behavior of these fields.
Waves and Optics: Investigates the nature of wave phenomena, including wavelength, frequency, and amplitude. This branch encompasses sound waves and light waves, exploring their reflection, refraction, and diffraction.
Modern Physics: Delves into the realms of quantum mechanics, examining the wave-particle duality of matter and the uncertainty principle. Relativity, both special and general, investigates the relationship between space, time, gravity, and energy. Atomic and nuclear physics explore the structure and behavior of atoms and their nuclei.

Conservation Laws: Fundamental principles highlighting the constancy in certain quantities during physical processes.
- Conservation of Energy: Energy can transform between different forms, but its total amount remains constant in an isolated system.
- Conservation of Momentum: In a closed system, the total momentum of objects remains constant, even during collisions.
- Conservation of Charge: Electric charge is neither created nor destroyed, it is simply transferred between objects.
Force and Motion: Force is an interaction causing objects to accelerate. Understanding motion requires defining a frame of reference, a fixed point used to describe motion.
Energy Forms: Energy manifests in multiple forms:
- Kinetic Energy: Energy of motion, dependent on mass and velocity.
- Potential Energy: Stored energy based on an object's position or state.
- Mechanical Energy: The sum of kinetic and potential energy within a system.

Newton's Second Law: (F = ma), where F is force, m is mass, and a is acceleration. This equation relates the force acting on an object to its resulting acceleration.
Work-Energy Theorem: (W = \Delta KE), where W is work done on an object and (\Delta KE) is the change in its kinetic energy. This theorem connects work to the change in an object's kinetic energy.
Ideal Gas Law: (PV = nRT), where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature. This law describes the relationship between pressure, volume, temperature, and the amount of gas in an ideal gas system.
Ohm's Law: (V = IR), where V is voltage, I is current, and R is resistance. This law describes the relationship between voltage, current, and resistance in a circuit.

SI Units: The International System of Units provides a standardized framework for measuring different quantities:
- Length: meters (m)
- Mass: kilograms (kg)
- Time: seconds (s)
- Force: newton (N)
- Energy: joule (J)
- Voltage: volt (V)
