  • 1. NokeshSATELLITE by Prabhakar
  • 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. 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. 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. 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. 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. Escape Velocity of a Satellite:- maximumspeed to which a object is projected so that itmoves out of gravitational field .Luna 1
  • 8. The escape velocity of a satellite is with withLocatio Locatio respect Ve[2] respect Ve[2]n n to toon the 617.5 kthe Sun Suns m/s, gravity: Mercury at theon Merc 4.3 km/ 67.7 km s Mercury Sunsury, s /s gravity: , gravity:

  • 11. Orbital Velocity:- velocity at which ansatellite rotates around a planet.Orbital velocity of a satellite =√grRelation between orbital velocity and Escapevelocity
  • 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. Height of a satellite:- theexpression to find out height ofsatellite is
  • 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. 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. Kepler’s law of aerial velocityAccording to kepler’s 2nd law , a planetcovers equal area in equal interval of time.
  • 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
