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.

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!
JD 제공2020년 5월 19일
Truly amazing for the students aspiring in the field of science and in the real-life application. And also for those who want to revise the concepts of physics.
RG 제공2020년 4월 27일
The course is very useful and is presented in a pleasant way so that we can understand the subject matter clearly and use them in solving real world problems.
H 제공2020년 4월 16일
Very informative course and the way the speakers voice out the lesson is not boring and it makes us more energetic to learn Phyiscs
자주 묻는 질문
When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
What is the refund policy?
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
Is financial aid available?
Yes, Coursera provides financial aid to learners who cannot afford the fee. Apply for it by clicking on the Financial Aid link beneath the "Enroll" button on the left. You’ll be prompted to complete an application and will be notified if you are approved. Learn more.
