.
- 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
