Still?
Stays still
Moving?
Stays moving.
What activity demonstrated this statement (still - stays still/ moving - stays moving)?
Rock and cup experiment.
Who developed the first liquid fuel rocket?
Robert Goddard
What advantage do liquid fuel rocket engines have?
Controllable
What causes the thrust or push in rocket engines?
Rapidly expanding gases in combustion chamber push down.
Spies from which country stole liquid-fuel rocket designs from our scientist?
Germany
Why did this country steal these liquid-fuel rocket designs?
To develop a missile to bomb England and the United States.
After World War II, which country became interested in the scientists who stole the liquid-fuel rocket designs from our scientist?
Soviet Union (Russia)
What did this country (Russia) do in 1957 that shocked the United States?
Sent up first satellite into space (sputnick)
What did sputnick cause the United States to do?
Take space exploration more seriously.
Why was the United States so far behind Russia with space exploration?
The United States did not rocket research from 1945 to 1958.
Who was the first man sent into space?
Yuri Gagarin
Who was the first American sent into space?
Alan Shepard.
What NASA mission carried one man into orbit?
Mercury
What NASA mission allowed the United States to send two men into space to practice docking and space walks?
Gemini.
What NASA mission allowed the United States to send three men on trip to the moon?
Apollo
What NASA mission allowed the United States to use a spacecraft many times in order to carry supplies and equipment into orbit?
The Space Shuttle
Why are rockets staged?
To allow the rocket to drop a portion when its fuel supply is used up.
What two forces work together to allow a satellite to orbit?
Inertia and gravity
What is a planet?
A large spherical body that orbits the sun.
What is a moon?
A large spherical body that orbits a planet.
What is an asteroid?
A small chunk of matter that orbits the sun or a planet.
What planets are in our solar system from the sun outward?
Mercury/Venus/Earth/Mars/Jupiter/Saturn/Uranus/Neptune/Pluto (this planet is disputed).
What plants are terrestrial?
Mercury/Venus/Earth/Mars/Pluto
What planets are gaseous?
Jupiter/Saturn/Uranus/Neptune
What is wrong about most solar system diagrams?
They can not possibly show both the relative size and distance.
What might be an appropriate response to the enormity of the universe?
“How Great Thou Art”
What do we call the different ‘faces’ of the moon?
Phases
What causes these different ‘faces’?
The changing amount of illuminated surface that we can see from earth based on its position.
How long does it take the moon to revolve around the earth?
About a month (‘moonth’)
What chance is there that our moon would just happen to rotate and revolve at the same rate as that we always see exactly the same side century after century?
Very little
What does this ‘chance’ for the moon rotating and revolving suggest to you?
God is great and very much in control of His creation.
What English scientist developed statements that defined motion?
Sir Isaac Newton
