Description de cours

In this course, you will develop your understanding of the basic concepts of physics. You will explore kinematics, with an emphasis on linear motion; different kinds of forces; energy transformations; the properties of mechanical waves and sound; and electricity and magnetism. You will enhance your scientific investigation skills as you test laws of physics. In addition, you will analyse the interrelationships between physics and technology, and consider the impact of technological applications of physics on society and the environment.

You will need a computer and Internet access and a calculator.

Unit 1: Waves and Sound

You might be sitting peacefully in your living room, when a truck rumbles by or a jet thunders overhead. The windows may rattle and the floor might shake. Even though the truck or jet is far away, you hear the noise and may even feel it. These are common examples of what are called mechanical waves. Waves play an important part in our lives. In this unit you will learn that mechanical waves have specific characteristics and predictable properties and sound is a mechanical wave. Mechanical waves can affect structures, society, and the environment in positive and negative ways. There are four lessons in this unit and at the end of each lesson you will answer questions about the content of the lesson and apply your new problem-solving skills. At the end of the unit you will submit all your answers to those Key Questions for marking.

Unit 2: Kinematics

You might spend a lot of your time sitting or standing but there is a good chance that you also drive a car, play a sport, or move around in some way. Motion and transportation are an important part of our daily lives. In this unit, you will learn about the basic relationships between time, distance, and motion. You will study the motion of projectiles (things that fly through the air) and how gravity determines the path of a ball in flight. You will also think about how transportation affects the environment and how GPS technology impacts society. In this unit you will learn that motion involves a change in the position of an object over time and motion can be described using mathematical relationships. Many technologies that apply concepts related to kinematics have societal and environmental implications. There are four lessons in this unit and at the end of each lesson you will answer questions about the content of the lesson and apply your new problem-solving skills. At the end of the unit you will submit all your answers to those Key Questions for marking.

Unit 3: Forces

Whether you are making a trip to buy groceries or play soccer with a group of friends, you are experiencing a world ruled by Newton’s laws. You probably aren’t thinking about words like force, acceleration, and gravity most of the time, but everything you do depends on the relationship between these concepts. Things that you use every day, such as a pair of shoes that has been carefully designed to provide you with the most comfort and usability, are manufactured using these physics concepts. In this unit, you will consider the role that physics plays in sports and how an understanding of these concepts can be used to improve the life of people who depend on prosthetic devices. By the end of this unit you will understand two important big ideas: Forces can change the motion of an object and the applications of Newton’s laws of motion have led to technological developments that affect society and the environment. There are four lessons in this unit and at the end of each lesson you will answer questions about the content of the lesson and apply your new problem-solving skills. At the end of the unit you will submit all your answers to those Key Questions for marking.

Unit 4: Energy and Society

In today’s society, it might seem as if we are trapped between the demand for more electricity and the need to use less electricity to protect the environment. Once you understand how electricity is generated, the choices involved become clearer. In this unit, you will examine energy transformations and how they are used in everyday life.

Energy is one of the concepts that tie the entire field of physics together. By the end of this unit, you will see how all of the different forms of energy are connected. After completing this unit, you will be able to

• explain and use the concepts of work, power, energy, and the law of conservation of energy

• describe methods of generating electricity and compare their efficiencies

• analyze and assess technologies that involve the transformation of thermal energy

• describe and compare the different types of nuclear radiation

• describe and compare nuclear fission and nuclear fusion

Unit 5: Electricity and Magnetism

Electric power has become an indispensable part of our lives. As we have increasingly come up with more ways to use electric power to improve our lives, we have also come to realize that generating electricity can impose a tremendous burden on the environment. We have some difficult choices ahead of us, related to how we generate and use electricity. In this unit, you will explore some of these problems and build your understanding of electricity. After completing this unit, you will be able to

• explain how electricity travels through electric circuits

• solve problems involving charge, current, potential difference, electrical energy, resistance,and power

• evaluate alternative forms of electrical energy

• explain the impact of technologies related to electromagnetism

• explain how the electrical grid functions.

There are four lessons in this unit and at the end of each lesson you will answer questions about the content of the lesson and apply your new problem-solving skills. At the end of the unit you will submit all your answers to those Key Questions for marking. At the end of the unit there is a Practice Test. It will help you prepare for the Final Test. After you have studied your course materials and reviewed the Key Questions, you should try to answer all the questions in a two-hour period. Practice Test Suggested Answers are provided so that you can mark the test yourself. Instructions will be given at the end of Lesson 20.
