Презентация по астрономии (физике) на тему "Законы Кеплера" на английском языке

• 1 слайд

  Kepler's laws of planetary motion
  

• 2 слайд

  Tycho Brahe
  1546 –1601
  Danish astronomer
  Johannes Kepler
  1571 – 1630
  German mathematician, astronomer, and astrologer
  

• 3 слайд

  Kepler's first law
  The law of Orbits (of Ellipses)
  
  The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus
  

• 4 слайд

  Drawing an ellipse
  

• 5 слайд

  
  Orbit Eccentricity
  
  The eccentricity of an ellipse is the ratio of the distance
  between the foci to the major axis of the ellipse.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  The eccentricity is zero for a circle.
  

• 6 слайд

  Examples of Ellipse Eccentricity
  Mars 0.093 Neptune 0.010
  Earth 0.017 Pluto 0.248
  

• 7 слайд

  Astronomical unit
  is unit of length
  is equal the average distance from Earth to the Sun
  is used primarily for measuring distances within the Solar System
  Is a fundamental component in the definition of another unit of astronomical length, the parsec (pc)
  1 au = 149597870700 m ≈ 150 000 000 km
  1 au = 4.8481×10−6 pc
  1 au = 1.5813×10−5 ly
  

• 8 слайд

  Parsec
  The parsec (the parallax of one arcsecond) is a unit of length used to measure large distances to astronomical objects outside the Solar System
  
  1 pc = 648000 π au
  

• 9 слайд

  Kepler's second law
  The Law of Equal Areas
  An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time
  

• 10 слайд

  Kepler's third law
  The Law of Periods (of Harmonies)
  The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun
  Every planet has the same T2/R3 ratio
  

• 11 слайд

  The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
  

• 12 слайд

  Data: Law of Periods
  
  

• 13 слайд

  The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
  

Краткое описание документа:

Данная презентация призвана служить как инструмент для визуализации изучаемого материала во время лекции учителя на тему "Законы движения планет (Законы Кеплера)".

Включает в себя информацию о каждом из трех законов движения планет, поясняет такие понятия, как эксцентриситет орбиты планеты, астрономическая единица, парсек и другие.

Может быть использована не только на уроках астрономии, но и на уроках физики при изучении механического движения.

Презентация составлена на английском языке.
