Study Notes
Mechanics
- Kinematics: Describes motion without considering the cause. Includes concepts like displacement, velocity, acceleration, and their graphical representations. Understanding equations of motion for constant acceleration is crucial for solving problems. Uniform circular motion introduces concepts of angular velocity and acceleration.
- Dynamics: Explores the causes of motion (forces). Newton's laws of motion are central, addressing inertia, force, mass, acceleration, and interaction pairs. The concept of equilibrium is important. Applications include free-body diagrams, inclined planes, and friction. Work, energy, and power are also covered under dynamics, emphasizing the transformation of energy in different forms (kinetic, potential, etc.).
- Circular Motion and Gravitation: Understanding the forces and motions involved in uniform circular motion and the implications of centripetal force. Newton's law of universal gravitation and its applications to planetary motion and satellites.
- Simple Harmonic Motion: Defines periodic motion with oscillatory behavior. Concepts like amplitude, period, frequency, and phase should be understood. Examples include simple pendulums, springs, and SHM in waves.
Thermal Physics
- Thermometry and Heat: Describing temperature scales (Celsius, Kelvin) and their relationship. Understanding heat transfer (conduction, convection, radiation). Specific heat capacity.
- Thermodynamics: The laws of thermodynamics. The first law—conservation of energy—relating heat, work, and internal energy. The second law—entropy and irreversibility—and its consequences for energy transfer processes. The third law—absolute zero—. The concept of ideal gas and its equation of state. Applications include heat engines and refrigerators.
Optics
- Reflection and Refraction: Laws of reflection and refraction. Understanding image formation by mirrors (plane, spherical, concave, convex) and lenses (thin lenses). Concepts like focal length, magnification, and image characteristics (real or virtual, inverted or upright).
- Wave Optics: Nature of light as an electromagnetic wave. Understanding wave superposition—interference (constructive and destructive), diffraction, and polarization. Applications include diffraction gratings.
Electricity and Magnetism
- Electrostatics: Electric charges, Coulomb's law, electric fields, electric potential, and capacitance. Applications include conductors, insulators, and dielectrics. Electrostatic induction and shielding.
- Current Electricity: Defining current, voltage, resistance, and Ohm's law. Series and parallel circuits and related problems. Kirchhoff's laws.
- Magnetism: Magnetic fields and forces, their sources (electric currents), and magnetic materials (ferromagnetic, diamagnetic, paramagnetic). Electromagnetism—the interaction between electricity and magnetism (e.g., magnetic fields produced by electric currents, electromagnetic induction, transformers, AC/DC).
Modern Physics
- Atomic Structure: The Rutherford model, Bohr model, and quantum mechanical model of the atom. Understanding energy levels, spectra, and electron configurations.
- Nuclear Physics: Properties of the nucleus, radioactivity (alpha, beta, gamma decay). Nuclear reactions (fission and fusion). Applications include uses in medicine, industry, and energy generation.
- Wave Nature of Matter and Light: De Broglie wavelength, wave-particle duality, principles of quantum mechanics. Concepts of quantization, orbitals, probability, tunneling. Applications of these ideas range from microscopes to materials science.
