Gravity
One of the factors that affects gravity; the amount of matter in an object
What is mass?
This planet is closest to the Sun in our Solar System
What is Mercury?
This planet is the sixth planet away from the Sun in our Solar System
What is Saturn?
This model says that the earth is the center of the universe and everything revolves around it
What is the geocentric model?
This is what we call a star and all of the objects that travel around it
What is a solar system?
A factor that affects gravity; the closeness of two objects
What is proximity?
This planet is the second closest planet to the Sun in our Solar System
What is Venus?
This planet is the seventh planet away from the Sun in our Solar System
What is Uranus?
This model, as stated by Nicolaus Copernicus, says that the Sun is the center of our Solar System and everything revolves around it
What is the heliocentric model?
These are the three criteria for a planet
What are:
1) It must orbit a star.
2) It must be big enough to have enough gravity to force it into a spherical shape.
3) It must be big enough that its gravity cleared away any other objects of a similar size near its orbit.
At the beginning of our universe, this force pulled vast spirals of dust together to form planets.
What is gravity?
This planet is the third closest planet to the Sun in our Solar System
What is Earth?
This planet is the eighth planet away from the Sun in our Solar System
What is Neptune?
This is the time when the universe began
What is the Big Bang?
The Earth's average distance from the sun is 1 AU. A planet with an AU of .72 would be (closer or farther) from the sun than a planet with an AU of 5.20.
What is closer?
This is the force that holds the planets in orbit around the Sun in our solar system
What is gravity?
This planet is the fourth closest planet to the Sun in our Solar System
What is Mars?
This icy ring is where the dwarf planet Pluto lives
What is the Kuiper Belt?
When an object turns on its own internal axis
What is rotation?
Two things you should do if you want to be successful in Science class
What is pay attention in class and study?
The force of gravity is affected by these two things
Mass and proximity
This planet is the fifth closest planet to the Sun in our Solar System
What is Jupiter?
This spherical shell is the outer edge of our solar system and the farthest point where the Sun's gravitational force reaches
What is the Oort Cloud?
This is when an object circles around the center of another object
What is revolution?
Three things you should do if you want to be successful in all of your class
What is pay attention, participate, and study?
