Gravity & Inertia
These are the two factors gravity depends on.
What is mass and the distance between the objects?
A ball of ice, dust and frozen gases that orbits the sun in an elliptical orbit.
What is a comet?
THE NICKNAME FOR MARS IS......?
What is THE RED PLANET
The farthest planet from the sun, with the longest time of revolution.
What is NEPTUNE?
The Earth-centered model
What is the geocentric model?
The force that holds all the planets in their orbit.
What is GRAVITY?
The Solar system consists of these things. (name at least 5)
What is the sun, planets and their moons, meteors, asteroids, comets and dwarf planets?
What is they are small, rocky, closer together, closer to the sun, shorter orbital path/year, less moons, no rings? (must have 2)
The distance between planets varies greatly. The inner planets are relatively ____________ while the outer planets are relatively ______________.
What is close together and far apart?
The Sun-centered model.
What is the heliocentric model?
These are the 2 reasons the Earth orbits around the sun.
What is the sun's gravity pulls on Earth while inertia keeps Earth moving ahead?
Chunks of space rocks that are too small and too numerous to be considered planets.
What are asteroids?
Venus and Earth are alike in terms of their . . .
a. direction of rotation
b. atmosphere
c. size
d. temperature
What is c. size?
This planet is unique because it rotates on its side and has a retrograde rotation.
What is URANUS?
The ideas from these 4 astronomers helped our understanding of the solar system.
This object would have the greatest gravitational pull on Pluto's orbit.
a. Sun
b. Earth
c. Moon
What is the sun?
The reason why Pluto is a dwarf planet.
What is it doesn't clear its orbital neighborhood?
This planet is one of the four inner planets, has no moons, is the smallest planet and has the shortest year.
What is Mercury?
The outer planets all these 3 things in common.
What is they are much larger than the inner planets, made of gas, lots of moons and have rings, farther apart, longer orbits and farther from the sun? (must have 3 of these things)
These 2 astronomers would not agree on their models of the solar system.
Who are ...
One of these (Aristotle or Ptolemy)
and
One of these (Copernicus or Galileo)?
The law that states: an object in motion with remain in motion until a force acts upon it. This is the reason the planets are in constant motion.
What is: The law of Inertia?
Explain the difference between a meteoroid, a meteor, and a meteorite.
meteoroids are in space, can fall through the atmosphere.
meteors are the streaks of light produced from a burning meteoroid
meteorites are pieces of a meteoroid that reach the Earth's surface.
This planet has a thick atmosphere of CO2, retrograde rotation, hottest planet and a day is longer than a year.
What is VENUS?
This is the order of the planets from the Asteroid belt to the Kuiper belt.
What is Jupiter, Saturn, Uranus and Neptune?
