Chapter 1: The Science of Physics Introduction Chapter 1: The Science of Physics 1.1 The Science of Physics 1.2 The Development of Scientific Knowledge 1.3 Physics is Useful

Chapter 1 Objectives Describe the process of inquiry and the relationship between inquiry and learning science. Describe the difference between matter and energy. Explain the relationship between a theory, a hypothesis and an experiment. Describe how scientific evidence is used to judge truth. Describe at least three examples of how physics knowledge is used in a career or occupation outside of physics.

Chapter 1 Vocabulary Terms natural law process analysis inquiry hypothesis experiment theory energy matter scientific evidence objectivity repeatability *Read Chapter One as an introduction. There is no accompanying investigation.

1.1 The Science of Physics Three fundamental aspects of Physics: Describing the organization of the universe. matter and energy Understanding the natural laws that govern the universe. belief that all events follow a set of laws that do not change Deducing and applying natural laws. science as a process

*The universe consists of only matter and energy 1.1 The Science of Physics Matter and Energy *The universe consists of only matter and energy

*We will explore Physics using inquiry through observation. 1.1 The Science of Physics Inquiry and Observation *We will explore Physics using inquiry through observation.

1.1 Inquiry Three valuable things are learned by discovering the natural laws through inquiry: It includes very practical knowledge. Once you know how something generally works, you can often figure out how to make it work for you. You will learn to solve real-life problems.

Using Problem Solving Techniques Step 1 Determine what the problem asks you to find out. Step 2 Identify the information you are given. Step 3 Identify laws or relationships. Step 4 Apply the given information and the relationships.

1.2 Development of Scientific Knowledge Models, Evidence, Analysis and Theories

1.2 Development of Scientific Knowledge Importance of Experiments We use experiments to test and evaluate theories.

1.2 Development of Scientific Knowledge Scientific Evidence Graphs and charts Images and sketches Measurements and data

1.2 Development of Scientific Knowledge Scientific Knowledge and the Solar System Early civilizations believed the Earth was covered by a dome on which the sun, stars and planets moved. In the Middle Ages, people thought the sun, stars and planets circled the Earth. Today we know the earth and planets orbit the sun.
