  1. 1. NokeshSATELLITE by Prabhakar
  2. 2. Satellite:- revolves around planet, Uniform velocity, fixed orbit Satellite are of two types:- 1.Artificial satellite •Ex-polar satellite 2.Natural satellite •Ex-moon
  3. 3. Natural Satellite:- A Natural Satellite is a Natural Body which revolvesaround(orbits) a Planet .It is usually called moon and islarge and ball shaped.There are 177 natural satellite in our solar system. Mercury-0 Venus-0 Earth-1 Jupiter-67 Saturn-62 Uranus-27 Neptune-13 Mars-2 Pluto-5
  4. 4. Artificial Satellite:-A Artificial Satellite is an object which has been placedinto orbit by human endeavour.Sputnik 1 –launched by Soviet union in 1957.Artificial Satellite is of two types :-1..Geostationary Satellite2. Polar Satellite.
  5. 5. Geostationary Satellite1.Rotates around the Earth over equator2.Fixed over a particular place3.40,000 km above the Earth surface4.Time period is 24 hours5.Used in telecommunication
  6. 6. Polar Satellite1.Rotates around the Earth from pole to pole2.Rotate around the Earth 8-10 times per day3.Only 300-400 km above the earth surface4.Time period is 2-3 hours5.Used in weather broadcasting ,remote sensing and G.p.s
  7. 7. Escape Velocity of a Satellite:- maximumspeed to which a object is projected so that itmoves out of gravitational field .Luna 1

  11. 11. Orbital Velocity:- velocity at which ansatellite rotates around a planet.Orbital velocity of a satellite =√grRelation between orbital velocity and Escapevelocity
  12. 12. Time Period of a satellite:- timetaken by a satellite for 1 revolution.The time period of a satellite T=2∏r×√r √GM
  13. 13. Height of a satellite:- theexpression to find out height ofsatellite is
  14. 14. Total Energy of a satellite :-Kinetic energy of a satellite= GMm 2rPotential energy of a satellite= -GMm rTotal energy of a satellite= K.E-P.E =GMm - GMm 2r r =-GMm 2r
  15. 15. Kepler‘s law of Elliptical orbitAccording to kepler’s 1st law the orbits of all planetsare elliptical and sun remains at one of the focus
  16. 16. Kepler’s law of aerial velocityAccording to kepler’s 2nd law , a planetcovers equal area in equal interval of time.
  17. 17. Kepler’s law of time periodAccording to kepler’s 3rd law ,square of thetime period is directly proportional to thecube of the semi-major axis. T² r³
