Study Notes
Overview of Physics
- Physics is a fundamental science, alongside biology and chemistry, focusing on the study of matter, energy, and their interactions.
- It plays a critical role in understanding both celestial and terrestrial phenomena.
Pioneers of Physics
- Nicolaus Copernicus (1473–1543): Proposed the heliocentric model, positioning the Sun at the center of the universe rather than Earth.
- Galileo Galilei (1564–1642): Supported the heliocentric view, establishing that Earth and other planets revolve around a stationary Sun.
- Isaac Newton (1643–1727): Developed universal gravitation and the three laws of motion, forming the foundation of "Newtonian mechanics."
- Benjamin Franklin (1706–1790): Demonstrated that lightning is an electrical phenomenon, which can be safely conducted into the ground.
- Charles-Augustin de Coulomb (1736–1806): The SI unit of electric charge, the Coulomb, is named in recognition of his contributions to electricity and magnetism.
- Amedeo Avogadro (1776–1856): Introduced the hypothesis that equal volumes of gases at the same temperature and pressure contain an equal number of molecules.
- Marie Curie (1867–1934): Discovered the radioactive elements polonium and radium, significantly impacting physics, chemistry, and medicine.
- Albert Einstein (1879–1955): Known for the theory of mass-energy equivalence and special relativity, revolutionizing approaches to physics.
- Niels Bohr (1885–1962): Made significant contributions to atomic structure and quantum mechanics.
Branches of Physics
- Classical Physics: Encompasses areas like mechanics, energy, electricity, heat, sound, light, and magnetism.
- Modern Physics: Explores nuclear physics, quantum physics, astrophysics, and theories of relativity.
Mechanics
- Mechanics studies motion and forces acting on bodies within a system, encompassing four fundamental forces:
- Gravitational
- Electromagnetic
- Nuclear
- Quantum
- Gravitational and electrical forces drive everyday physical events.
Properties of States of Matter
- The laws of mechanics apply at the atomic level, explaining the predictable behavior of large aggregates of molecules.
