  1. Physical Science An introduction

  2. Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. What is Science?

  3. Formal – logic and mathematics • Physical – astronomy, chemistry, physics, earth sciences • Life – biology • Social – sociology and psychology • Applied –engineering and healthcare • Interdisciplinary – artificial intelligence, bioethics, statistics, military science • Philosophy/history – scientific method, science policy, pseudoscience Parts of Science

  4. The scale of the universe mapped to the branches of science and the hierarch of science.

  5. Some marine animals are subjected to a lunar cycle. They increase and decrease in size with the waxing and waning of the moon such as the sea urchin.

  6. DNA determines the genetic structure of all known life.

  7. The study of physics and chemistry of nature. What is physical science?

  8. The physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms or the subatomic particles). What is physics?

  9. Describing the nature, measuring and quantifying of bodies and their motion, dynamics etc. • Newton's laws of motion • Mass, force and weight • Momentum and conservation of energy • Gravity, theories of gravity • Energy, work, and their relationship • Motion, position, and energy • Different forms of Energy, their interconversion and the inevitable loss of energy in the form of heat (Thermodynamics) • Energy conservation, conversion, and transfer. • Energy source the transfer of energy from one source to work in another. • Kinetic molecular theory • Phases of mater and phase transitions • Temperature and thermometers • Energy and heat • Heat flow: conduction, convection, and radiation • The three laws of thermodynamics • The principles of waves and sound • The principles of electricity, magnetism, and electromagnetism • The principles, sources, and properties of light

  10. Built upon concepts from physics, addresses phenomena associated with the structure, composition and energetics of matter as well as the changes it undergoes. What is chemistry?

  11. Physical chemistry • Chemical thermodynamics • Reaction kinetics • Molecular structure • Quantum chemistry • Spectroscopy
