Newton's law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Kepler's laws of planetary motion:
1.The orbit of a planet is an ellipse with the Sun at one of the two foci.
2. A line segment joining a planet and the Sun sweeps out equal areas during equal
intervals of time.[1]
3.The square of the orbital period of a planet is proportional to the cube of the semi-
major axis of its orbit.
Newton's laws of motion:
Laws of thermodynamics:
Zeroth law of thermodynamics: If two systems are in thermal equilibrium respectively with
a third system, they must be in thermal equilibrium with each other. This law helps define
the notion of temperature.
∙First law of thermodynamics: When energy passes, as work, as heat, or with matter, into or out from a system, its internal energy changes in accord with the law of conservation of energy. Equivalently, perpetual motion machines of the first kind are impossible.
∙Second law of thermodynamics: In a natural thermodynamic process, the sum of the entropies of the participating thermodynamic systems increases. Equivalently, perpetual motion machines of the second kind are impossible.
∙Third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches absolute zero. With the exception of glasses the entropy of a
system at absolute zero is typically close to zero, and is equal to the log of the multiplicity of the quantum ground state.。
