Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies. This on-demand course is recommended for senior high school and beginning university students and anyone with a curiosity about basic physics. (The survey tells us that it's often used by science teachers, too.) The course uses rich multimedia tutorials to present the material: film clips of key experiments, animations and worked example problems, all with a friendly narrator. You'll do a range of interesting practice problems, and in an optional component, you will use your ingenuity to complete at-home experiments using simple, everyday materials. You will need some high-school mathematics: arithmetic, a little algebra, quadratic equations, and the sine, cosine and tangent functions from trigonometry. The course does not use calculus. However, we do provide a study aid introducing the calculus that would accompany this course if it were taught in a university. By studying mechanics in this course, you will understand with greater depth many of the wonders around you in everyday life, in technology and in the universe at large. Meanwhile, we think you'll have some fun, too....

Velocity and Acceleration

Here we introduce kinematics, in which we describe and quantify movement of objects through space over time. Motion is so important to mechanics (and most of physics) that we'll spend a few weeks establishing the tools and techniques we'll need. We'll leave explaining motion to the later weeks, starting with Newton's laws in week 4. Here we study the simplest case: motion in a straight line....

Newton's Laws of Motion

After describing and quantifying motion (weeks 2 and 3), we now start explaining it with Newton's three laws of motion. Knowledge of Newton's laws and the ability to apply them to various situations will allow us to explain much of the motion we observe in the world around us. They are also very important for analysing things (like bridges) that don't move much (a subject called Statics that's important in some Engineering programs). Because Newton's laws are so important, week 4 has five lessons, as well as slightly longer quizzes than the previous chapters. ...

Great course. Good explanations and examples. The quizes and tests are not very easy sometimes, but they do you let think again. Very enjoyable! Just the course I was looking for a long time!
