Introduction to Physics
- Physics is the study of nature and its laws
- Nature around us is diverse and contains large phenomena (e.g., winds, water, planets, rainbows, etc.)
- Physics helps understand how the human body functions, and energy from the sun and nucleus
- Physics is about discovering basic laws from observed events
- Simple rules, like gravity and motion, can explain complex events
- The study of basic rules is crucial for all life domains
- Physics leads to useful applications in various fields, including bio and medical sciences.
Physics and Mathematics
- Mathematics is the language of physics; it simplifies describing nature.
- Formulas and equations help predict outcomes from basic laws
Units
- Physics involves measuring and comparing physical quantities
- Measuring physical quantities requires standard units
- Units need international acceptance for clear communication globally
- The General Conference on Weights and Measures (CGPM) establishes standards
Fundamental and Derived Quantities
- Fundamental quantities are independent; examples include length, mass, time
- Derived quantities are calculated from fundamental quantities; examples include force, density, volume
SI Units
- The International System of Units (SI) is widely used worldwide.
- The CGPM established the SI system in 1971
Definitions of Base Units
-
Necessary properties of base units include:
- Invariability; standards cannot change
- Availability; standards must be easily compared
-
Meter: The distance traveled by light in a vacuum in 1/299,792,458 of a second.
-
Kilogram: The mass of a specific platinum-iridium cylinder kept at the International Bureau of Weights and Measures.
-
Second: Defined based on the particular radiation emitted by a Cesium-133 atom
-
Ampere: Defined using the force between two parallel current-carrying wires.
-
Kelvin: Fraction of the thermodynamic temperature of the triple point of water
-
Mole: The amount of substance containing the same number of elementary entities as there are atoms in 0.012 kg of carbon-12
-
Candela: The luminous intensity of a specific blackbody
Dimensional Analysis
- Dimensional analysis is used to check equations for correctness
- Quantities on both sides of an equation must have identical dimensions.
- Useful, though can't determine dimensionless constants or complex relations.
