Study Notes
Classical Mechanics
- Classical mechanics describes the motion of macroscopic objects, typically those visible to the naked eye.
- It relies on Newton's laws of motion, which relate force, mass, and acceleration.
- Key concepts include:
- Force: A push or pull that can cause an object to accelerate.
- Mass: A measure of an object's resistance to acceleration.
- Acceleration: The rate of change of an object's velocity.
- Newton's first law (inertia): 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: 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: For every action, there is an equal and opposite reaction.
- Applications include:
- Calculating trajectories of projectiles.
- Analyzing the motion of planets.
- Designing machines and structures.
- Limitations of classical mechanics: It does not accurately predict the behavior of objects at extremely high speeds (approaching the speed of light) or at the atomic level.
Thermodynamics
- Thermodynamics deals with the relationships between heat, work, and energy.
- Key concepts include:
- Internal energy: The total energy of the particles within a system.
- Heat: Energy transferred between systems due to a temperature difference.
- Work: Energy transferred to or from a system by a force acting through a distance.
- The first law of thermodynamics: Energy can neither be created nor destroyed, only transformed from one form to another. (ΔU = Q - W)
- The second law of thermodynamics: The total entropy of an isolated system can only increase over time.
- The third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches absolute zero.
- Applications include:
- Designing engines and power plants.
- Understanding phase transitions (solid, liquid, gas).
- Analyzing chemical reactions.
- Predicting the behavior of systems involving heat.
Quantum Mechanics
- Quantum mechanics describes the physical phenomena at the atomic and subatomic level.
- It relies on concepts such as:
- Quantization of energy and other quantities.
- Wave-particle duality: Particles exhibit both wave-like and particle-like properties.
- Superposition: A quantum system can exist in multiple states simultaneously until measured.
- Uncertainty principle: It is impossible to know both the position and momentum of a particle with perfect accuracy.
- Key equations and principles:
- Schrödinger equation: A fundamental equation in quantum mechanics that describes the evolution of a quantum system.
- Heisenberg uncertainty principle: ΔxΔp ≥ h/4π, where Δx is the uncertainty in position, Δp is the uncertainty in momentum, and h is the Planck constant.
- Applications include:
- Understanding atomic structure and behavior.
- Developing lasers and transistors.
- Predicting the behavior of molecules.
- Designing new materials with enhanced properties.
- Explaining phenomena like radioactivity and electron transitions.
- Discrepancies: Quantum mechanics differs fundamentally from classical mechanics in its probabilistic nature and in its description of the quantum world.
