Physics is the science of the movement of matter and energy through space and time. The many different disciplines under the umbrella of physics all attempt to answer the basic question of how the universe and reality work.
Branches of Physics
1. 1. Classical Mechanics
  2. Electromagnetism
  3. Relativity
  4. Thermodynamics
  5. Quantum Mechanics
Newton's Laws of Motion
1. Physical bodies remain at rest or continue a constant velocity, unless acted upon by an outside force
2. Rate of change in momentum is proportional to the producing resultant force and occurs in the direction of that force
3. To every action there is an equal and opposite reaction
4. The Laws of Thermodynamics:
5. Two thermodynamic systems individually in thermal equilibrium with a third will be in thermal equilibrium with each other
6. The change in energy of a closed thermodynamic system = the sum of heat energy supplied to the system + work done on the system
7. Total entropy of isolated thermodynamic systems increases over time to a maximum value
8. No system can reach absolute zero without an infinite number of processes
