Edited at 2023-01-28 15:04:26One Hundred Years of Solitude is the masterpiece of Gabriel Garcia Marquez. Reading this book begins with making sense of the characters' relationships, which are centered on the Buendía family and tells the story of the family's prosperity and decline, internal relationships and political struggles, self-mixing and rebirth over the course of a hundred years.

Project management is the process of applying specialized knowledge, skills, tools, and methods to project activities so that the project can achieve or exceed the set needs and expectations within the constraints of limited resources. This diagram provides a comprehensive overview of the 8 components of the project management process and can be used as a generic template for direct application.

Newton's laws of mechanics
Historical evolution
Aristotle: Force is what keeps objects in motion
Galileo: No force is needed to maintain the motion of an object
Descartes: An object moving at a uniform speed will not change its state of motion when no force is acted upon.
Newton: All objects always remain at rest or move in a straight line at a uniform speed when no external force is applied. Force is what changes the state of motion of an object
Newton's first law
Content: All objects always maintain a state of uniform linear motion or a state of rest when they are not acted upon by external forces.
Newton's first law cannot be simply derived from experiments. It is based on experiments, analysis and scientific reasoning.
Force is what changes the state of motion of an object, and inertia is what maintains the motion of an object.
To explore Newton's first law, the car must be slid down from the same slope and the same height every time. The purpose is to make the initial speed of the car slide to the horizontal plane equal.
The meaning of Newton's first law
Revealed the relationship between motion and force
Confirmed the effect of force: force is the cause of changing the state of motion of an object
Recognize that inertia is also a property of objects
inertia
Content: The property that all objects maintain their original state of motion is called inertia
Things to note when understanding “inertia”
"All objects" includes all solids, liquids, and gases that are subject to force or are not subject to force, and are in motion or at rest.
Inertia is a property inherent in the object itself, not a force
Therefore, it is wrong to say "the object is subject to inertia" or "the object is subject to inertial force".
Inertia is not a force, it only has magnitude but no direction.
It is necessary to distinguish between "Newton's first law" and the "inertia" of objects, The former reveals the laws of motion that an object follows when there is no external force, and the latter shows the properties of the object.
Inertia has both beneficial and harmful aspects. Sometimes we have to make use of inertia, and sometimes we have to prevent the harm caused by inertia, but this does not mean "creating" inertia or "eliminating" inertia.
The same object has inertia regardless of whether it is at rest or moving, moving fast or slow, or receiving force or not, and the magnitude of the inertia remains unchanged.
Inertia is only related to the mass of the object. An object with a large mass has a greater inertia and has nothing to do with the state of motion of the object. Inertia has no direction.
How to explain the phenomenon of inertia
①Determine the research object
② Find out the original state of movement of the research object
③What changes have occurred?
④What phenomenon occurs because the inertia research object maintains its original motion state?
