What is the name of the mission program that got humanity to the moon?
Apollo
What two things does gravity depend on?
Mass and distance
Name two major differences between Jovian and Terrestrial planets
Options:
gas/rock
distance from star
mass
What is the first stage of a star's life?
Nebula
Why can't light escape a black hole?
The force of gravity is too strong
What was the primary goal of the Apollo Program?
To land on the moon or to beat the Soviet Union in doing so.
If the mass of one object is doubled, what happens to the force of gravity?
it doubles
What keeps the planets in orbit around the sun?
Gravity
What determines a star's life path?
mass
How do we detect black holes, if we can't see them?
By the effect they have on nearby objects
What is the name of the current program back to the moon and eventually to mars?
Artemis
If the distance between objects is doubled, what happens to the force of gravity?
It is divided by 4
Which is more dense Earth, or Jupiter?
Earth
What happens to low-mass stars at the end of their lives?
They become white dwarfs
List the three types of galaxies
Spiral, Elliptical, and Irregular
In what decades did the Apollo missions occur?
60's and 70's
What role does gravity play in star and planet formation?
It pulls and compressed all of the gas and dust particles together
What are the planets of our solar system, in order from closest to the Sun, to farthest?
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
What is one of the paths a star can take? Make sure to include at least three stages
Need at least three on one of the following two paths:
proto to main to giant to white dwarf
proto to massive star to super giant to super nova to neutron or black hole
What is the name of the galaxy closest to us and also on a collision course?
Andromeda Galaxy
What are the names of all three of the astronauts that were on the Apollo 11 mission?
Neil Armstrong, Buzz Aldrin, and Michael Collins
A student says the gravity depends on weight. Are they correct? Explain
No, weight is the force of gravity and changes based on where you are. Gravity depends on mass and distance. Mass is the amount of matter there is in an object.
