Study Notes
Classical Mechanics
- Classical mechanics describes the motion of macroscopic objects, using Newton's laws of motion.
- Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
- Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, F = ma.
- Newton's third law states that for every action, there is an equal and opposite reaction.
- Concepts of force, mass, momentum, energy, work, and power are fundamental in classical mechanics.
- Applications include satellite trajectories, projectile motion, and the behavior of everyday objects.
Thermodynamics
- Thermodynamics deals with heat, work, and temperature.
- The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.
- The second law of thermodynamics states that the entropy of an isolated system can only increase over time.
- The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
- Key concepts include enthalpy, entropy, and free energy.
- Applications are found in engines, refrigerators, and other thermal devices.
Electromagnetism
- Electromagnetism describes the interaction between electric charges and magnetic fields.
- Coulomb's law describes the electrostatic force between two charged particles.
- Gauss's law relates the electric field to the enclosed charge.
- Ampere's law relates magnetic fields to electric currents.
- Faraday's law describes the generation of an electromotive force (EMF) by a changing magnetic field.
- Applications are numerous, including electrical circuits, motors, generators, and electromagnetic waves, including light.
Optics
- Optics deals with the behavior and properties of light.
- Light can be described as both a wave and a particle, this is known as wave-particle duality.
- Reflection, refraction, and diffraction are key concepts regarding light's interaction with surfaces and materials.
- Lenses and mirrors are used to manipulate light's path.
- Applications range from telescopes and microscopes to fiber optics and laser technology.
Quantum Mechanics
- Quantum mechanics describes the physics of the microscopic world, including atoms and subatomic particles.
- Key concepts include wave-particle duality, quantization of energy, and uncertainty principle.
- Heisenberg's uncertainty principle states that certain pairs of physical properties, like position and momentum, cannot be known with perfect accuracy simultaneously.
- Quantum mechanics has revolutionized our understanding of matter and energy at the atomic and subatomic level.
- Applications include the development of lasers, transistors, and modern electronics.
Atomic Physics
- Atomic physics explores the structure and behavior of atoms.
- Bohr model describes the atom as having a nucleus with orbiting electrons in specific energy levels.
- Quantum mechanical model provides a more accurate description of electrons in orbitals.
- Spectroscopy is a key tool for studying atomic structures and transitions between energy levels.
- Applications are in understanding matter, chemical reactions, and the development of new materials.
Relativity
- Relativity describes the relationship between space and time, particularly at high speeds and in strong gravitational fields.
- Special relativity deals with the relationship between space and time for observers in uniform motion.
- General relativity describes the relationship between space, time, gravity, and the distribution of matter and energy.
- Key concepts in relativity are spacetime, time dilation, length contraction, and gravitational fields.
