  1. An Introduction to Physics Chapter 0:

  2. Objectives: • Determine what Physics governs and controls • Conclude that Physics is the building block of all sciences • Identify areas in your life that will be impacted by studying Physics • Differentiate between laws and theories • Provide reasons why problem-solving techniques are vital to the study of Physics

  3. Definition of Physics • Physics is the branch of science that describes the motion and energy of all matter throughout the universe • What are some examples of Physics in everyday life?

  4. Physics often considered the most fundamental of all sciences • Biology: study of living organisms – uses principles of fluid movement in body • Chemistry: study of matter – Physics explains why chemical reactions take place • Geology: study of Earth – use Physics to analyze earthquakes • Astronomy: study of everything outside of Earth's atmosphere – uses laws of gravity & relativity • What are some careers that use Physics every day?

  5. What is a Physicist? • A person who is an expert in or who studies Physics • Theoretical Physicist: researches previous theories and mathematical models to form new theories in Physics • Albert Einstein, Plato, Aristotle • Experimental Physicist: focuses on performing experiments to develop and confirm physical theories (ex: Aristotle)

  6. Physics and Technology • What is the difference between science and technology? • Science is a system of knowledge that is concerned with establishing accurate conclusions about the behavior of everything in the universe • Technology is the field that uses scientific knowledge to develop material products or processes that satisfy human needs/desires

  7. What are some examples of how science has played a role in improving technology? • Robotics, bridges, superconductors, liquid crystal displays (LCD's), magnetic levitation, etc.

  8. Electromagnetism Fluid dynamics Mathematical Physics Statistical Mechanics High-energy Physics Atomic Physics Molecular Physics Nuclear Physics Quantum Physics Subdivisions of Physics • Mechanics • Thermodynamics • Cryogenics • Plasma Physics • Solid state Physics • Geophysics • Astrophysics • Acoustics • Optics

  9. Theories, Laws, & Problem-Solving • A theory is a scientific conclusion that attempts to explain natural occurrences and typically has been tested in the lab but not proven with absolute certainty • Laws are the final degree of scientific certainty • Scientific method is an orderly procedure used by scientists • Problem-solving method is a procedure that aids in solving problems
