Which two factors affect the force of gravity between objects?
Mass and size
Distance and gravity
Inertia and Velocity
Mass and distance
Which would properly model how the universe expands?
Place paper clips on the ground to represent galaxies, then keep adding more and more paper clips.
Use balloons laid on on the floor to represent galaxies, then increase the space between the balloons to show how space is expanding.
Use a string with beads on it to represent the galaxies, then continue to add more beads.
Fill up a cup with water to represent space, then place glitter in the water to represent galaxies, and allow the glitter to sink to the bottom to show them coming together.
What is the Doppler effect?
A shift in wavelengths due to a moving source.
A method for analyzing the movement of galaxies.
A and B
A only
B only
In which scenario would a planet have the HIGHEST acceleration?
When it is closest to the Sun.
When the gravitational force of the Sun is low.
When it crashes into another planet.
When the moon's gravity is pulling on its oceans creating tides.
If two objects in space slam into each other, which object has the greater force? (hint: Newton's 3rd law)
The object with less mass.
The object with more mass.
The object with more volume.
Neither, they both apply the same force to each other.
Scientists observe that galaxies are ____-shifted, meaning that they are all moving _______ us.
red, toward
red, away from
blue, toward
blue, away from
In a solar system, _________ orbit around a ___________, and may also have ________ orbiting them.
stars, sun, moons
planets, moon, meteors
planets, star, moons
meteors, sun, stars
Which of the following would DECREASE the gravitational force between objects A and B?
Increase the mass of object A.
Increase the mass of object B.
Decrease the distance between objects A and B.
Increase the distance between objects A and B.
Which of the following correctly describes spring and neap tides?
Spring tides only occur during a full moon, neap tides only occur during a new moon.
Spring tides occur when the Earth, moon, and sun are in a straight line, while neap tides occur when the moon and sun form a ninety degree angle with the Earth.
Spring tides have less of a difference in its high and low tides compared to neap tides.
Spring tides cause high tides and neap tides cause low tides.
Which of the following is the most important and underlying force that drives the formation of nebulas, stars, galaxies, planets, solar systems, and influences all masses in the universe?
Applied force
Friction
Gravitational force
Magnetic force
