Introduction to Mechanics

Purpose of Course show close

Physics 101 is the first course in the Introduction to Physics sequence. In general, the quest of physics is to develop descriptions of the natural world that correspond closely to actual observations. Given this definition, the story behind everything in the universe is one of physics. In practice, the field of physics is more often limited to the discovery and refinement of the basic laws that underlie the behavior of matter and energy. While biology is founded upon physics, in practice, the study of biology generally assumes that the present understanding of physical laws is accurate. Chemistry is more closely dependent on physics and assumes that physical laws provide accurate predictions. Engineering, for the most part, is applied physics. In this course, we will study physics from the ground up, learning the basic principles of physical laws, their application to the behavior of objects, and the use of the scientific method in driving advances in this knowledge. This first course of the three-course series (the subsequent courses in the series are Introduction to Electromagnetism and Introduction to Modern Physics) will cover the area of physics known as classical mechanics. Classical mechanics is the study of motion based on the physics of Galileo Galilei and Isaac Newton. While mathematics is the language of physics, you will only need to be familiar with high school level algebra, geometry, and trigonometry. The small amount of additional math and calculus that we need will be developed during the course.

Course Information show close

Welcome to PHYS101. General information on this course and its requirements can be found below.

Primary Resources: This course is comprised of a range of different free online materials. However, the course makes primary use of the following resources:

Massachusetts Institute of Technology: Professor Walter Lewin’s Physics I: Classical Mechanics Video Lectures
The textbook to accompany this course is OpenStax College’s College Physics.You may find it helpful to download the PDF version and save the PDF file as it will be used throughout the entire course. Problems will be assigned from this text. These are extremely important as they will be similar to those on the final exams. Solutions to the problem sets are available, but it is important that you make every effort to solve the problems before looking at the solutions. Getting the answers is not what is important. It is more important that you understand how to go about finding the answers in a systematic way. The Student Solutions Manual for College Physics can be found here under Learning Resources.
Additional problems will be assigned from Calculus-Based Physicsby Jeffery W. Schnick. Please feel free to browse this text, but our use of the text will only be for problemsand their solutions. Although there will be no readings assigned from this text, it may be useful to look at the appropriate sections of the text when working the problems, particularly if you get stuck.
University of Toronto: Professor David Harrison’s “Physics Flash Animations”

Requirements for Completion: In order to complete this course, you will need to work through each unit and all of its readings and lectures. You will also need to complete:

The Final Exam

Note that you will only receive an official grade on your Final Exam. However, in order to adequately prepare for this exam, you will need to work through the problems assigned throughout the course.

In order to “pass” this course, you will need to earn a 70% or higher on the Final Exam. Your score on the exam will be tabulated as soon as you complete it. If you do not pass the exam, you may take it again.

Time Commitment: This course should take you a total of about 130 hours to complete. Each unit includes a “time advisory” that lists the amount of time you are expected to spend on it and each of its subunits. These should help you plan your time accordingly. It may be useful to take a look at these time advisories and to determine how much time you have over the next few weeks to complete each unit, and then to set goals for yourself. For example, Unit 1 should take approximately 6.75 hours. Perhaps you can sit with your calendar and decide to complete subunit 1.1 (a total of 3.75 hours) on Monday night and subunit 1.2 (a total of 3 hours) on Tuesday night. Unit 2 should take you 13.25 hours to complete. Perhaps you can schedule time to complete subunit 2.1 (a total of 4 hours) on Wednesday night; subunit 2.2 (a total of 2.75 hours) on Thursday night; etc.

Tips/Suggestions: Take comprehensive notes as you complete the resources in this course. It may also help to keep the problems you solve in one notebook for easy reference. These notes will serve as a useful review as you prepare and study for the Final Exam.

Good luck to you in this undertaking you are about to embark on.Upon successful completion of this course, the student will be able to:

Instructions: Please click on the link above, and view the entire lecture, pausing to take notes, before moving on to the reading below.

As mentioned in the course information section, Professor Lewin’s lectures can be difficult and fast-paced. We don’t expect you to immediately be able to fully master all of the content he presents. Note that the most important concepts will be covered within the text you will be reading next. As you watch, focus instead on grasping the major points of the lecture. What do you think they are? Jot these down in your notes. You can also use the Saylor Foundation’s “Lecture Aid” (DOC) as a supplement and guide while watching this lecture. This document includes some useful equations and some of the key points that Professor Lewin makes. If you are determined to master the material covered in this lecture, we applaud you! We recommend watching the sections in which Lewin works on and converts his equations slowly and deliberately. He does a lot of quick calculations, but watch them at your own pace until you feel you can master them. Refer to the Lecture Aid for more assistance.

Note, too, that the “Powers of 10” video that Lewin refers to has been removed from this recording for copyright reasons. Don’t worry about this; the video establishes the concept of orders of magnitude, which we have defined in the Lecture Aid.

Watching this lecture should take approximately 1 hour and 15 minutes.

Unit 2: Motion in a Straight Line

Our formal study of physics begins with kinematics, which is defined as the study of motion without considering its causes. The word “kinematics” comes from a Greek term meaning “motion.” In this unit, we will study motion without worrying about what forces cause or change it. Such considerations come in later units. In this unit, we will examine the simplest type of motion – namely, motion along a straight line, or one-dimensional motion.

Unit 3: Kinematics in Two Dimensions

Most motions in nature follow curved paths rather than straight lines. Motion along a curved path on a flat surface or a plane is two-dimensional and thus described by two-dimensional kinematics. Two-dimensional kinematics is a simple extension of the one-dimensional kinematics covered in the previous unit. This simple extension will allow us to apply physics to many more situations, and it will also yield unexpected insights about nature.

Unit 4: Dynamics

The study of motion is kinematics, which describes the way objects move, their velocity, and their acceleration. Dynamicsconsider the forces that affect the motion of moving objects. Newton’s laws of motion are the foundation of dynamics. These laws provide examples of the breadth and simplicity of principles under which nature functions. They are also universal laws in that they apply to similar situations on Earth as well as in space.

Unit 6: Work and Energy

Energy is the capacity of a physical system to perform work. It plays an essential role both in everyday events and in scientific phenomena. You can probably name many forms of energy from that provided by our foods to the energy we use to run our cars to the sunlight that warms us on the beach. Not only does energy have many interesting forms, but it is involved in almost all phenomena and is one of the most important concepts of physics.

Energy can change forms, but it cannot appear from nothing or disappear without a trace. Thus, energy is one of a handful of physical quantities that we say is conserved.

Unit 7: Momentum and Collisions

We use the term momentum in various ways in everyday language. We speak of sports teams gaining and maintaining the momentum to win. Generally, momentum implies a tendency to continue on course – to move in the same direction – and is associated with mass and velocity. Momentum has its most important application in analyzing collision problems, and, like energy, is important because it is conserved. Only a few physical quantities are conserved in nature, and studying them yields fundamental insight into how nature works, as we shall see in our study of momentum.

Unit 8: Statics and Torque

What might desks, bridges, buildings, trees, and mountains have in common – at least in the eyes of a physicist? The answer is that they are ordinarily motionless relative to the Earth. Thus, their acceleration in the Earth frame of reference is zero. Newton’s second law states that net F = ma,so the net external force is zero on all stationary objects and for all objects moving at constant velocity. There are forces acting, but they are balanced. That is, the forces are in equilibrium.

Unit 9: Angular Momentum

Why do tornadoes spin so rapidly? The answer is that the air masses that produce tornadoes are themselves rotating, and when the radii of the air masses decrease, their rate of rotation increases. An ice skater increases her spin in an exactly analogous way. The skater starts her rotation with outstretched limbs and increases her spin by pulling them in toward her body. The same physics describes the spin of a skater and the wrenching force of a tornado. Clearly, force, energy, and power are associated with rotational motion. These and other aspects of rotational motion are covered in this unit. We will see that all important aspects of rotational motion either have already been defined for linear motion or have exact analogs in linear motion.
