2. Why is the orbit time less for a planet close to the sun?

  • It accelerates
  • The centripetal force is large
  • Travels a shorter distance+travels faster because of a greater gravitational force
  • Travels a longer distance+small gravitational force

3. What is velocity?

  • Speed in a particular direction
  • Change in acceleration
  • A scaler quantity
  • Speed with no direction

4. Where do polar orbits orbit and how long does it take?

  • Above the poles + 24 hours
  • Above the poles + 90 minutes
  • Above the equator + 90 minutes
  • Above the equator + 24 hours
