Honors Review so far for Q3 Mini 3

What are the factors affecting gravitational force between 2 objects?

• Diameter & Distance

• Volume & Distance

• Mass & Distance

• Volume & Mass

By increasing two objects mass, what happens to the gravitational force between the objects?

• Increases

• Decreases

• Remains Constant

• Alters the radius and diameter

If the distance between two objects increases, what happens to the gravitational force?

• Increases

• Decreases

• Remains Constant

• Alters the diameter of the object

What is Kepler's 2nd Law?

• All objects travel in ellipse's around the sun

• The further a planet is, the longer it takes to orbit the sun

• All areas are equal in size within an orbit

• The closer the object is to the sun, the faster it's speed

The further the planet is the from the Sun, the _________ the orbit and the __________ it takes to travel around the sun.

• smaller, quicker

• larger, longer

• larger, quicker

• smaller, longer

What is the correct sequence of events that lead to the creation of our solar system

• Solar Nebula-> Protostellar Disk-> Fusion-> Star-> Planetesimals-> Planets

• Protostellar Disk ->

  Star-> Fusion-> Nebula->Planets-> Planetesimals

• Solar Nebula-> Fusion-> Protostellar Disk-> Star-> Planetesimals-> Planets

• Protostellar Nebula-> Planetesimals-> Fusion-> Star-> Planets

How did the planets within our solar system, including Earth, form?

• An ancient star's star dust made the planets

• The Solar Nebula, held together by gravity made heavier masses central and lighter masses on the outskirts

• Nuclear fusion in the sun created such a large gravitational force it forced planets to revolve around it

• By forces humans have yet to understand

How did planetesimals become planets

• Snowball effect, collecting more ad more dust as they orbit the Sun

• Smaller Planetesimals colliding together making larger planets

• Planets losing dust and gas to larger planetesimals due to more gravity

• Dust and gas was distributed evenly throughout to solar system

If you wanted to measure the distance between the Sun and a neighboring star, which unit of measure should you use?

• Kilometers

• Astronomical Units

• Light-Years

• Light- Speed

which of the following distances between objects would require multiple astronomical units?

• Distance from Earth to Sun

• Distance from Earth to Moon

• Distance from Earth to another star

• Distance from Earth to Saturn
