Classical Mechanics and Thermodynamics Quiz

Study Notes

Classical Mechanics

Classical mechanics describes the motion of macroscopic objects, such as planets and cars, at speeds much slower than the speed of light.
It is based on Newton's laws of motion and gravitation.
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.
Newton's third law states that for every action, there is an equal and opposite reaction.
Key concepts include: force, mass, acceleration, momentum, energy, work, power, and gravitation.
Applications include calculating trajectories of projectiles, analyzing the motion of systems of particles, and understanding the behavior of simple machines.

Thermodynamics

Thermodynamics deals with heat, work, and temperature and their relationship to energy and entropy.
It considers macroscopic properties of systems without regard to the microscopic structure of the system.
Laws of thermodynamics, describing the fundamental principles of thermodynamic processes, are important:
- Zeroth law: If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other. This establishes the concept of temperature.
- First law: Energy cannot be created or destroyed, only converted from one form to another. The change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
- Second law: The total entropy of an isolated system can only increase over time and remains constant in reversible processes.
  - This leads to the concept of spontaneous processes.
- Third law: The entropy of a perfect crystal at absolute zero temperature is zero.
Key concepts include: heat, work, temperature, internal energy, enthalpy, entropy, and specific heat.
Applications include understanding heat engines, refrigerators, and other thermodynamic devices, as well as phase transitions.

Electromagnetism

Electromagnetism describes the interaction between electric charges and magnetic fields.
Electric charges create electric fields, and moving electric charges create magnetic fields.
Electric and magnetic fields are intrinsically related and can be described by Maxwell's equations.
Key concepts include: electric charge, electric field, electric potential, magnetic field, magnetic flux, and electromagnetic waves.
Applications include understanding electric circuits, motors, generators, and various technological applications based on electromagnetic principles.

Optics

Optics deals with the behavior and properties of light.
Light can be described as waves or as particles (photons).
Key concepts include: reflection, refraction, diffraction, interference, polarization, wave-particle duality, and different types of lenses and mirrors.
Applications include various optical instruments like telescopes, microscopes, and cameras.

Quantum Mechanics

Quantum mechanics describes the behavior of matter and energy at the atomic and subatomic levels.
It's based on the concept that energy and matter can exist only in discrete packets called quanta.
Key concepts include: wave-particle duality, quantization of energy, uncertainty principle, quantum numbers, and the Schrödinger equation.
Applications include understanding the structure of atoms and molecules, semiconductor devices, and lasers.

Relativity

Relativity describes the relationship between space and time.
Special relativity deals with the motion of objects at constant velocities relative to each other.
General relativity deals with gravity as a curvature of spacetime, considering the effects of gravity and acceleration.
Key concepts include: spacetime, time dilation, length contraction, mass-energy equivalence, and gravitational lensing.
