(A relationship, Hubble's)

Hubble's law, A relationship between a galaxy's distance from us and its velocity through space (which is interpreted as evidence of the expanding universe) so that the furher away a galaxy is the faster it is receding

牛頓運動定律

niuˊ dunˋ yunˋ dongˋ dingˋ luuˋ

(Newton's, Three fundamental)

Newton's laws of motion, Three fundamental laws of classical physics developed by English physicist and mathematician Sir Isaac Newton (1642–1727). 1. A body continues in its state of constant velocity unless it is acted upon by an external force. 2. An unbalanced force acting on a body is equal to the acceleration produced multiplied the the inertial mass of the body. 3. In a system where no external forces are present, every acting force opposed by a opposing force of equal magnitude

(A set, Kepler's)

Kepler's laws, A set of three scientific laws describing the motion of planets around the Sun published by Johannes Kepler (1571–1630). They define the shape of planetary orbits (1. All planets move along elliptical orbits with the Sun located at one focus.), explain how a planet's velocity changes during an orbit (2. During each orbit, a line connecting a planet with the Sun sweeps out equal areas in equal time intervals.), and relate a planet's orbital period to its distance from the Sun (3. The square of the planet's orbital period (P) is proportional to the cube of its semimajor axis).

基爾霍夫定律

ji ˉ erˇ huoˋ fu ˉ dingˋ luuˋ

(Kirchhoff's, Three laws)

Kirchhoff's laws, Three laws that explain the formation of spectra, named for German physicist Guastav Kirchhoff (1824–87). An incandescent solid or gas under high pressure (such as a star) will produce a continuous spectrum. A low-density gas (such as a neon sign) will radiate an emission (bright line) spectrum. Continuous radiation viewed through a low-density gas will produce an absorption (dark line) spectrum.
