Study Notes
Classical Physics
- Classical physics encompasses branches established before the 20th century, including mechanics, acoustics, optics, thermodynamics, and electromagnetism.
- Classical mechanics deals with forces acting on bodies and can be divided into statics, kinematics, and dynamics.
- Mechanics is further split into solid mechanics and fluid mechanics, which includes hydrostatics, hydrodynamics, aerodynamics, and pneumatics.
- Theories in classical physics, like Newton's laws, serve as frameworks for other fields and are foundational concepts for all physicists.
Theories and Research
- Classical mechanics is effective for objects larger than atoms and moving slowly relative to the speed of light.
- Chaos theory emerged in the 20th century as a subset of classical mechanics.
- Physics continues to evolve, with various specialized areas still actively researched, including quantum mechanics and thermodynamics.
Scientific Method
- Scientific theories in physics are tested using the scientific method for validity through experimental comparison.
- Scientific laws are succinct statements reflecting fundamental principles, such as Newton's law of universal gravitation.
