Chapter 1: The Science of Physics

Chapter 1 Objectives

1 Describe the process of inquiry and the

relationship between inquiry and

learning science.

2 Describe the difference between matter

and energy.

3 Explain the relationship between a

theory, a hypothesis and an experiment.

4 Describe how scientific evidence is used

to judge truth.

5 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

*Read Chapter One as an introduction

There is no accompanying investigation.

1.1 The Science of Physics

Three fundamental aspects of Physics:

1 Describing the organization of the universe.

 matter and energy

2 Understanding the natural laws that govern

the universe.

 belief that all events follow a set of laws

that do not change

3 Deducing and applying natural laws.

 science as a process

1.1 The Science of Physics

Matter and Energy

*The universe consists of only matter and

energy

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:

1 It includes very practical knowledge.

2 Once you know how something

generally works, you can often figure

out how to make it work for you.

3 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

Measurements and data Graphs and charts Images and sketches

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.
