Classical Mechanics
- Describes the motion of macroscopic objects.
- Key concepts include:
- Newton's laws of motion: Relate a body and the forces acting upon it.
- Force, mass, acceleration: Fundamental to understanding object motion.
- Energy and Work: How energy is transferred and transformed.
- Momentum: A measure of motion involving mass, velocity, and direction.
- Rotational motion: Motion around an axis.
- Gravity: The fundamental force of attraction between objects with mass.
Thermodynamics
- Deals with heat, temperature, and energy transfer.
- Key concepts include:
- Temperature: Average kinetic energy of particles in a substance.
- Heat: Transfer of thermal energy between objects at different temperatures.
- Laws of thermodynamics: Govern heat and energy behavior in systems.
