Study Notes
Applied Physics
- Applied physics is the application of physics to solve scientific or engineering problems.
- It is considered a bridge between physics and engineering.
- It is distinguished from "pure" physics by factors such as motivation, attitude, and relationship to technology or science.
Physics as a Science
- It is the study of the laws and theories that explain the structure of the universe.
- It is concerned with the matter and energy that make up the universe.
Traditional Domains of Physics
- Heat
- Light
- Sound
- Electricity and magnetism
- Mechanics
The Scientific Method
- It is the basic fundamental of any study of the physical universe.
- It involves observation and generalization of observed phenomena to find coherent patterns.
Patterns of Scientific Method
- Defining problems: identifying problems that need solutions and specifying them as clearly as possible.
- Observation: recording concise statements of what has been observed.
- Measurement: formulating mathematical statements that relate to observations.
- Experimentation: testing hypotheses through actual experiments.
- Making hypotheses: constructing tentative answers to problems based on observed laws.
- Developing theories: creating tentative explanations from observations and testing.
Law vs Theory
- Law: correlates a series of observations, is empirical, and summarizes experimental results.
- Theory: explains observations, predicts what has been observed, and remains tentative until directly observable.
