100
These two characteristics determine how strong gravity is.
What are mass and distance?
100
Pluto got demoted to a dwarf planet because it does not do what?
What is clear its orbit?
100
Besides planets, these objects also orbit the sun.
What are comets, dwarf planets, and asteroids?
100
Speed equals what?
What is distance divided by time?
100
This distance/time graph displaces what speed?
What is at rest?
100
This object most likely killed the dinosaurs.
What is an asteroid?
200
If Timmy is pushing an object with 50 N to the left and Valery is pushing that same object with 50 N to the left, the net force is what? (Daily Double: Include both force and direction.)
What is 100 N to the left.
200
The discovery of this band of icy gas and rocks led to the demotion of Pluto as a planet, since Pluto was found to not clear its orbit.
What is the Kuiper Belt?
200
This area of the solar system was thought to have been a proto (early) planet that broke apart and left large chunks of rocks and dust behind.
What is the asteroid belt?
200
A walker travels 1000 meters in 10 minutes. The speed she is traveling at is... (Use the Units!)
What is 100 m/min?
200
This distance/time graph shows what kind of speed?
What is constant speed?
200
This object develops a tail made of burning gas when it gets too close to the sun.
What is a comet?
300
What factor causes the moon to orbit the Earth?
What is the Earth's gravitational pull?
300
This spherical area of frozen debris was discovered because some comets came from farther away than the Kuiper Belt.
What is the Oort Cloud?
300
These two functions of the atmosphere help protect Earth.
What are protection from UV rays and meteors hitting earth?
300
A student travels 50 meters in 5 seconds. The speed that the student traveled is... (use UNITS)
What is 10 m/sec?
300
This distance/time graph shows what kind of speed?
What is speeding up?
300
This object travels in a band that can be found between Mars and Jupiter.
What is an asteroid?
400
If a car hits a brick wall and stops, what force moves the person?
What is inertia (an object in motion wants to stay in motion)?
400
Comets originate from what two places?
What are Oort Cloud and Kuiper Belt?
400
A planet must meet what three conditions?
What are:
it must be round
it must clear its orbit
it must orbit the sun?
400
Velocity can be defined as this.
What is speed with a direction?
400
This graph shows what kind of speed on this distance/time graph?
What is slowing down?
400
Much like an asteroid, this object can be found in space, outside our atmosphere.
What is a meteoroid?
500
These two forces keep the planets rotating around the sun in a straight line.
What are gravity and inertia?
500
Dwarf planets have been found in this ONE area.
What is the Kuiper Belt?
500
For a planet to be considered habitable, it must contain what three things?
What are:
Breathable atmosphere
Liquid water
Not too hot and not too cold because it is not too close or too far away from the sun
500
A bird flies 11 hours and covers a total of 99 miles. What speed was the bird traveling at?
What is 9 miles/hour?
500
Daily double! For 1000 points, describe the motion on this graph.
What is a constant speed going away, stopped, constant speed going back toward the start, and being stopped again?
500
This object is sometimes called a shooting star because it burns up once it crosses into Earth's atmosphere. Once it hits the ground, it's name becomes what. Name both for a daily double of 1000 points.
What is a meteor and meteorite?
