Answers
1
Why can't we feel gravity from small objects like a pencil?
Everyday objects don't have gravity
The force is too small unless the object is REALLY BIG!
There is no gravity in our classroom
Sometimes gravity pulls and sometimes it pushes
2
If the mass of an object increases, what happens to the gravitational force?
Increases
Stays the same
Decreases
3
What is centripetal force?
An inward or toward-center push or pull
Equal to distance divided by time with direction
The force that pulls objects towards Earth's center
It's the straight line along the edge of a circle
4
What is an asteroid?
Small icy object orbiting the sun with a tail
A meteor that reaches Earth's surface
Rocky object orbiting the sun between Mars and Jupiter
A shooting star
5
What is a meteor?
A meteor that reaches Earth's surface
Rocky object orbiting the sun between Mars and Jupiter
A shooting star in Earth's atmosphere
A small rock IN SPACE before it reaches Earth
6
If the distance between two objects increases, the gravitational force...
Stays the same
Decreases
Increases
7
What force causes the gas and dust to clump together over time?
Inertia
Gravity
Velocity
Mass
8
What is friction?
The lack of any air molecules
The tendency for an object not to change motion
The force caused by one surface or object rubbing against another
Friction caused by air molecules
9
What is a nebula?
Daughter of Thanos
When a dying star explodes
A cloud of gas and dust in space
A group of solar systems and stars
10
Which planet would have the strongest gravitational pull?
Jupiter
Earth
Saturn
Neptune
11
Which describes the orbital motion of planets in our solar system?
circular and clockwise
Elliptical and counterclockwise
Elliptical and clockwise
circular and counterclockwise
12
Based on the shape of its orbit, the mystery object is most likely:
Comet
Star
Asteroid
Planet
13
What is a meteoroid?
A meteor that reaches Earth's surface
A small rock IN SPACE before it reaches Earth
A shooting star in Earth's atmosphere
Rocky object orbiting the sun between Mars and Jupiter
14
When using CER, what is evidence?
An opinion
Your QIR answer to the question
Numbers or data that proves your claim
Science-y explanation with vocab
15
What is a tangent line?
An inward or toward-center push or pull
Equal to distance divided by time with direction
The force that pulls objects towards Earth's center
It's the straight line along the edge of a circle
16
What is required for an object to travel in circular motion?
Inertia
An outward push or pull
An inward push or pull
Gravity
17
What is velocity?
An inward or toward-center push or pull
Equal to distance divided by time with direction
It's the straight line along the edge of a circle
The force that pulls objects towards Earth's center
18
Why is the sun's gravity strong enough for the planets to orbit it?
The sun doesn't have much mass
The sun is close to the planets
The sun is far from the planets
The sun has a lot of mass
19
Which path will the space probe take?
a
c
b
20
If an astronaut lands on another planet, what changes?
The astronaut's weight

21
At which position would the object experience the strongest pull of gravity from the sun?
7
8
5
1
22
Which object in our solar system has the most mass?
Sun
Saturn
Jupiter
Earth
23
What is a vacuum?
The lack of any air molecules
The tendency for an object not to change motion
The force caused by one surface or object rubbing against another
Friction caused by air molecules
24
What is a comet?
Rocky object orbiting the sun between Mars and Jupiter
Small icy object orbiting the sun with a tail
A meteor that reaches Earth's surface
A shooting star
25
If centripetal force is removed, which direction will the object travel?
Backwards
In a curve
In a circle
Outward in a straight line
26
What is a supernova?
A Marvel Character
A cloud of gas and dust in space
A group of solar systems and stars
When a dying star explodes

Science-y explanation with vocab
28
What would happen if you dropped a bowling ball and feather on the MOON?
The feather would reach the ground first
The bowling ball would reach the ground first
They would hit the ground at the same time
Nothing - There is no gravity on the moon.
29
What is inertia?
The tendency for an object not to change motion
Friction caused by air molecules
The force caused by one surface or object rubbing against another
The lack of any air molecules
30
What type of force would you need to move a space probe through space from Earth to Jupiter?
A constant push toward Jupiter
A one-time push toward Jupiter
A one-time push in any direction
A constant pull toward Jupiter
31
What is a galaxy?
A cloud of gas and dust in space
When a dying star explodes
