Transcript

  • 1. P5a ‘Satellites and circular motion’
  • 2. P5a - What’s in today’s lesson?
    • Artificial satellites: low polar and geostationary orbits
    • Gravity: How does gravitational force affect objects?
    • Circular motion: What keeps things orbiting?
  • 3. Low polar orbits
    • Where?
    • Time to orbit?
    • Uses?
  • 4. Geostationary orbits
    • Where?
    • Time to orbit?
    • Uses?
  • 5. Gravitational force
  • 6. Gravitational force
    • Strength of gravitational pull between two objects depends on two things:
    M 1 M 2 d
  • 7. Gravitational force
    • So the closer to the Sun or another planet, the ________ the gravitational pull and the _________ an object will move
    • Q ~ Which planet orbits the sun fastest?
  • 8. Circular motion (p148)
    • Centripetal force is…
  • 9. Why don’t satellites fall?
  • 10. Why don’t satellites fall?
  • 11. P5a - What was in today’s lesson?
    • Artificial satellites: low polar and geostationary orbits
    • Gravity: How does gravitational force affect objects?
    • Circular motion: What keeps things orbiting?
