Why mechanics is most important branch of physics?
The first complete branch,furnish the basic concepts of whole physics, influence the other branches.
passages:
✧ Now we apply some principles to the motions of artificial satellites such as an orbiting Space Shuttle. In general, the principles of mechanics can be applied to
i. The motions of celestial objects so as to accurately predict events, in some cas many years before they happen, for example, the return of the Halley’s comet;
ii. The motions of ordinary objects on Earth , for example, an automobile or a thrown baball;
iii. The behavior of atoms, atomic particles, and subatomic particles, with considerable success.

§1-1Mechanical motion
questions:
● What must we introduce or consider when we describe the mechanical motion?
● Why do we usually study the idea models, such as particle and rigid body?
● When a body we study is regarded as a point particle ? or a rigid body?
● How can we describe the motion of a body or system ?
● How many kinds of the motion of the rigid body? And what they are?
● lace是什么意思Can you describe the Cartesian coordinates as a example in this ction?
Passage:
✧ It was indicated above that motion in mechanics is defined as the change in the mutual arrangement of the bodies. If we imagine a parate isolated body in a space where no others are prent, then we cannot speak of the motion of the body becau there is nothing with respect to which the body could change its position. It thus follows that if we intend to study the motion of a body, then we must indicate with respect to what other bodies the given motion occurs.
✧ To describe the motion of a body means to indicate for every moment of the time the position of the body in space and its velocity. allerganTo t the state of a mechanical system, we must indicate the positions and the velocities of all the bodies forming the system. A typical problem of mechanics consists in determinin
g the states of a system at all the following moments of time t when we know the state of the system at a certain initial moment t0 and also the laws governing the motion.
✧ It is simpler to treat a point particle than an extended body. We shall therefore first study the mechanics of a particle, and then go over to the mechanics of a rigid body. We shall start with kinematics, and then 调酒培训学校delve into dynamics. We remind our reader that kinematics studies the motion of bodies without regard to what caus this motion. Dynamics studies the motion of bodies with a view to what caus this motion to have the nature it does, i.e. with a view to the interactions between bodies.
