4
What would happen if the Sun exploded in terms of celestial movement?
celestial movement would continue
everything would be pushed away from the center
the sun can't explode
everything would be pushed towards from the center
5
How does distance affect gravity?
If an object is too close, then gravity won’t affect it
It doesn’t
The closer an object, the stronger the pull
The farther an object is, the stronger the pull
6
What are the two branches of Astrophysics
observational and physics
theoretical and astronomy
theoretical and observational
astronomy and physics
7
Why aren’t new planets formed in the Solar System any more?
The existing planets are too small to allow new planets
The existing planets are too large to allow new planets
The existing planets are mean
New planets can't just form
8
hat do we need to change to make pluto habitable?
Moons , planets around pluto, size and adding water
Size, atmosphere and moons
Adding schools, water, elements and people
Distance from the sun , size, composition and greenhouse gas
9
What are the two determining factors with gravity?
mass and distance
gravity and mass
mass and size
distance and gravity
10
"For every action there is a an equal and opposite reaction."
Newton's 4th Law
Newton's 2nd Law
Newton's 3rd Law
Newton's 1st Law
11
What are tidal forces?
What gives water pressure to all the houses
The force of the waves that make the moon move
The force of the moon that makes tsunamis
The force of the moon that makes waves in the ocean
12
Why does the universe continue to expand?
Because the universe is releasing a lot of energy
Because of the explosion from the big bang
Because the vacuum of space makes it bigger
Because more galaxies are forming
13
"Objects at rest remain at rest and objects in motion remain in motion"
Newton's first law
Newton's third law
Newton's second law
14
The greater the mass of anything, the greater its
mass
gravity
wallet size is
acceleration
15
Why does the universe continue to expand?
Dark energy
Light energy
Gasses expand when heated
New planets
16
The center of mass of two or more bodies, usually bodies orbiting around each other is called
ellipsis
gravity
barycenter
pulsar
17
What is special about the rotation of the moon in relation to the Earth?
The moon rotates around the Sun
There is a man on the moon
The same side of the Earth always faces the moon
The same side of the Moon always faces the Earth
18

tidal force
roche
pulsar
supernova
19
The birth of the universe is known as
The Black Hole
The Belgian Universe
The Big Bang Theory
Newton's laws of motion
20
