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....

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!

Total content of the course was very good. Daily life application based questions were also quite interesting. But there were also some negative points such as lectures were not very elaborated and the answer submission system in the quizzes were very frustrating.

Too little about stars & planets.

The videos are great and easy to follow.

The questions are significantly harder than anything introduced in the videos. While they give you just enough to answer the questions, there's no build-up to the hard questions. This slowed down my learning pace significantly as a result which was frustrating.

The way the tests accept the answers can lead to a very frustrating experience. The test would mark my answers wrong for no reason. Sometimes I would change nothing between tests and get the previously marked incorrect answer correct. Besides this glitch however this course was great.

Very good course for basic physics. If you're looking for a physic course to build the base for Mechanical Engineering, highly recommend this one.

not too good ,,because in assignments session they doesnt know what the right ans is, as in first assignment ,the ques is about circumference of circle as in google the exact ans is what they wronged it

This requires a high level understanding of maths (highest high school level) especially SI, and exponents. It is not suitable for people with no background in maths or physics

You never explain answers to the quiz problems?! If I need spend 20 minutes, for each problem, digging in the Internet for assistance, what value are you providing! Good bye

Few explanations, no feedback after doing things wrong.
