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.

Introduction and Basic Tools
This introductory section covers some basic tools you will need to solve some of the physics problems we will encounter later.
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.
Motion in Two Dimensions
Here we look at kinematics in two-dimensions – specifically, projectiles and objects in circular motion.
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.

MECHANICS: MOTION, FORCES, ENERGY AND GRAVITY, FROM PARTICLES TO PLANETS의 최상위 리뷰
The course is well-written, the teaching method is fun and entertaining. The instructor is very passionate and enthusiastic about physics.
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.
This course is really great for aspiring physicists and engineers. This made me more interested in this this field and helped me in visualizing the inner workings of the universe.
such a nice course for those students who want to improve their mechanics so it is a good platform.
