Questions and Answers
  • 1. 
    What is Gravity?
    • A. 

      Gravity is the force that causes smaller bodies to accelerate towards the surface of a larger body.

    • B. 

      Gravity is the force that causes smaller bodies to accelerate away from the surface of a larger body.

    • C. 

      Gravity is the force that causes larger bodies to accelerate towards the surface of a smaller body.

  • 2. 
    What are orbits?  
    • A. 

      A circular path around an object of any size

    • B. 

      A set distance and path that only planets take around the Sun.

    • C. 

      A set distance and path that a smaller celestial body takes around a bigger celestial body

  • 3. 
    Is the following TRUE or False? If a celestial body that was 500 km diameter was close to a celestial body that was 45677999 km diameter in space, the bigger object would form an orbit around the smaller body.
    • A. 

      True

    • B. 

      False

  • 4. 
    How do satellites remain in space for decades without being lost?  
    • A. 

      They are programmed to stay at one single spot and use rockets to stay in the same position

    • B. 

      They form an orbit around a bigger object such as the Earth and remain in in that orbital distance away from the surface of the planet forever.

    • C. 

      They are placed there by rockets and staffed by Astronauts who pilot them to required locations

  • 5. 
    What are the factors that influence orbits (Tick all the boxes that are correct)
    • A. 

      Size of the celestial bodies involved

    • B. 

      The force of gravity

    • C. 

      The temperature of the celestial bodies involved

    • D. 

      The speed that the celestial bodies are moving at

  • 6. 
    What is the value if the force of gravity on Earth?
    • A. 

      9.8 m/s/s

    • B. 

      12 m/s/s

    • C. 

      1 m/s/s

  • 7. 
    Is the value if g on Venus likely ti be the same as the value of Earth? Why or Why Not?
    • A. 

      Yes because the force of gravity is the same on every planet

    • B. 

      No because the force of gravity depends on the masses of the objects involved

    • C. 

      Yes because the force of gravity is determined by the Sun which is the same star for the Earth and for Venus

  • 8. 
    What are moons and how are they formed?
    • A. 

      Moons are mini planets that are too small to be classified as planets themselves

    • B. 

      Moons are natural satellites that form from debris from planetary collisions

    • C. 

      Moons are small offshoots from the Sun that form natural satellites around planets
