Inertia is a very important concept in Understanding of inertia， the more recognition of objects with properties of keeping original motion state， the inertia (object will remain at rest or of uniform motion in a straight line)， the nature of reason is not in the interior of the object， also has nothing to do with But due to the uniformity of the object of time and space Along with the development of modern physics， general relativity and proposed that inertia is around by its expression objects associated with space-time quality distribution determines the nature of the An important progress for inertial understanding of relationships with energy and With inertial energy point of view to broaden the understanding of inertia， also broaden the understanding of Based on inertial essence as the research perspective， this paper expounds on inertia of the concept of development and change， human understanding of nature of various inertial phenomenon to broaden the understanding of inertia， focusing on the based on the Newton classic time-space conditions to explore the establishment of the law of inertia and the inertia in the high school physics teaching concept， the law of inertia， grasps the inertia and life closely related， introduces the application of inertia on the science and
The first several finds gave the usual platitudes: read the book before you go to the lecture， don't get behind on assignments， ， advice that applies to any This book really makes an attempt to explain why physics is especially difficult， and what you have to do to cope with the In particular， Landa contradicts the frequently repeated idea that if you can't do the problems， you don't understand the Doing the problems is "hand-on experience" and though it's based on understanding the concepts， understanding isn't "Knowing and understanding does not mean you can solve problems on the same subject on your own， when your decision making skills will be in " "The ability to make a sequence of correct moves， that lead to the correct result in an efficient manner， is a skill entirely independent of the quality of one's understanding of the " It's like the difference between knowing how cars run and being able to do a tune- I'm not far enough into the book to be sure it will help me over the difficulties， but at least I have a clearer sense of the challenges of learning
