Introduction to Mechanics
Purpose of Course showclose
This course will survey physics concepts and their respective applications. It is intended as a basic introduction to the current physical understanding of our universe. Originally part of “Natural Philosophy,” the first scientific studies were conducted after Thales of Miletus established a rational basis for the understanding of natural phenomena circa 600 BCE. One of the Seven Sages of Greek philosophy, Thales sought to identify the substances that make up the natural world and explain how they produce the physical phenomena we observe. Prior to Thales, humans had explained events by attributing supernatural causes to them; his work represents the very beginning of scientific analysis.
The Scientific Method used today builds on this early foundation, but adds the essential underpinnings of evidence based on experiments or observation. Briefly, the modern scientific method involves forming a hypothesis about the cause of a general phenomenon, using that hypothetical model to predict the outcome of a specific example, and then testing that prediction by experiment or observation. A true prediction for a specific example does not prove the general hypothesis. However, one false prediction proves the general hypothesis invalid, or at least limited to special cases. Because of this property, Karl Popper, a noted 20th century philosopher, proposed that any scientific knowledge must be falsifiable—that is, there must be an experiment which could, in principle, show some prediction of the hypothesis to be false.
This is still the quest of physics today: to develop descriptions of the natural world that correspond more and more closely to actual observations. Given this definition, the story behind everything in the universe is in fact one of physics. In practice, however, the field of physics is more often limited to the discovery and refinement of the basic laws underlying 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, but still assumes that physical laws provide accurate predictions. Engineering is little more than applied physics, and so on.
In this course, we will study physics from the ground up, learning the basic principles of physical law, their application to the behavior of objects, and the use of the scientific method in driving advances in this knowledge. This first course of a threecourse series (the subsequent courses in the series are Introduction to Electromagnetism and Introduction to Quantum Mechanics) will focus on describing how objects move and interact. While mathematics is the language of physics, you will only need to be familiar with high schoollevel algebra, geometry, and trigonometry. The small amount of additional math and calculus we will need will be developed during the course.

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 fastpaced. 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 onedimensional 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 twodimensional and thus described by twodimensional kinematics. Twodimensional kinematics is a simple extension of the onedimensional 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.
Unit 6 Time Advisory show close
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.
