Chapter1: The Science of Physics

3. Chapter1 Objectives
1. Describe the process of inquiry and the relationship
between inquiry and learning science.
2. Describe the difference between matterand
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 careeroroccupation
outside of physics.

4. Chapter1 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.

5. 1.1 The Science of Physics
Three fundamental aspects of Physics:
1. Describing the organization of the universe.
 matter and energy
1. Understanding the natural laws that govern the
universe.
 belief that all events follow a set of laws that do
not change
1. Deducing and applying natural laws.
 science as a process

6. 1.1 The Science of Physics
Matterand Energy
*The universe consists of only matter and
energy

7. 1.1 The Science of Physics
Inquiry and Observation
*We will explore Physics using inquiry through
observation.

8. 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 yo u.
3. You will learn to solve real-life problems.

9. 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 orrelationships.
 Step 4
— Apply the given information and the
relationships.

10. Foundations of Physics Units

11. 1.2 Development of Scientific Knowledge
Models, Evidence, Analysis and Theories

12. 1.2 Development of Scientific Knowledge
Importance of Experiments
 We use experiments to test and evaluate theories.

13. 1.2 Development of Scientific Knowledge
Scientific Evidence
Measurements and data Graphs and chartsImages and sketches

14. 1.2 Development of Scientific Knowledge
Scientific Knowledge and the SolarSystem
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.

professions

16. 1.3 Physics is Useful
 Business and finance
 Art, music, and food

17. 1.3 Physics is Useful
 The relationship between
physics and otherfields
