Classical Mechanics and Thermodynamics Quiz

Classical Mechanics

• Classical mechanics describes the motion of macroscopic objects.
• It uses Newton's laws of motion and conservation principles (momentum, energy, angular momentum).
• Key concepts include velocity, acceleration, force, mass, inertia, momentum, energy, work, power, and potential energy.
• 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. (F=ma)
• Newton's third law states that for every action, there is an equal and opposite reaction.

Thermodynamics

• Thermodynamics deals with heat, work, and temperature.
• Key laws include the zeroth, first, second, and third laws of thermodynamics.
• The zeroth law defines thermal equilibrium.
• The first law states that energy cannot be created or destroyed, only transferred or changed from one form to another. (ΔU = Q - W)
• The second law states that the total entropy of an isolated system can never decrease over time.
• The third law states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

Electromagnetism

• Electromagnetism deals with electric and magnetic forces.
• Key concepts include electric charges, electric fields, magnetic fields, electric current, and electromagnetic waves.
• Coulomb's law describes the force between electric charges.
• Ampere's law describes the magnetic field created by electric currents.
• Faraday's law describes the induced electromotive force in a conductor due to a changing magnetic field. This is the basis for many electrical devices.
• Maxwell's equations unify the laws of electricity and magnetism, describing how electric and magnetic fields are generated and interact.

Optics

• Optics deals with light and its behavior.
• Key concepts include reflection, refraction, interference, diffraction, and polarization.
• Reflection is the bouncing of light off a surface.
• Refraction is the bending of light as it passes from one medium to another.
• Interference is the superposition of two or more light waves.
• Diffraction is the spreading of light waves as they pass through an aperture or around an obstacle.
• Polarization is the restriction of light waves to a particular plane of oscillation.

Modern Physics

• Modern physics includes relativity and quantum mechanics.
• Einstein's theory of special relativity describes the relationship between space and time in the context of constant velocities.
• Einstein's theory of general relativity describes gravity as a curvature of spacetime.
• Quantum mechanics describes the behavior of matter at the atomic and subatomic level.
• Key concepts in quantum mechanics include wave-particle duality, quantization, and uncertainty principle.

Atomic and Nuclear Physics

• Atomic physics deals with the structure and properties of atoms.
• Nuclear physics deals with the structure and properties of atomic nuclei.
• Models of the atom, including Bohr model, and quantum mechanical models.
• Concepts include isotopes, radioactivity (alpha, beta, gamma), nuclear reactions, and fission/fusion.
