牛顿第一定律:
The first law describes a fundamental property of matter,called inertia,as follows:
Every body remains in a state of rest or in a state of uniform motion (constant speed in a straight line) unless it is compelled by impressed forces to change that state.
牛顿第二定律
Newton's second law describes the manner in which a force compels a change of motion,at a rate of change called acceleration.It can be stated as follows:
Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which that force is impressed.
牛顿第三定律:
Newton's third law may be stated as follows:
Action and reaction are equal and opposite.
This law is often expressed as “for every action there is an equal and opposite reaction.”
热力学第一定律
First law of thermodynamics,about the conservation of energy
The change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to the system and the work done on the system.
热力学第二定律
Second law of thermodynamics,about entropy
The total entropy of any isolated thermodynamic system tends to increase over time,approaching a maximum value.
热力学第三定律
Third law of thermodynamics,about absolute zero temperature
As a system asymptotically approaches absolute zero of temperature all processes virtually cease and the entropy of the system asymptotically approaches a minimum value; also stated as:"the entropy of all systems and of all states of a system is zero at absolute zero" or equivalently "it is impossible to reach the absolute zero of temperature by any finite number of processes".
动量守恒原理
Conservation of momentum
The principle of conservation of momentum states that the total momentum of a closed system of objects (which has no interactions with external agents) is constant.One of the consequences of this is that the centre of mass of any system of objects will always continue with the same velocity unless acted on by a force outside the system.
其他基本概念:
万有引力定律:
Newton's Law of Gravity
Each object in the universe attracts each other body.
能量守恒:
Conservation of energy states that the total amount of energy in an isolated system remains constant,although it may change forms (for instance,friction turns kinetic energy into thermal energy).
Put simply,the law of conservation of energy states that energy can not be created or destroyed—it can only be changed from one form to another (such as electrical energy into heat energy).
