What does rotation mean?
spinning of an object on its axis
one object moving around another object
changing positions randomly
Which planet orbits the fastest?

Jupiter
Neptune
Mercury
What does revolution mean?
Spinning of an object around its axis
One object orbiting another object.
Random movement of an object.
What time period is represented by Earth's rotation?
year
month
day
hour
What time period is represented by Earth's revolution?
year
month
day
hour
What shape is Earth's orbit?
circle
ellipse
square
spiral
What is Kepler's 3rd law?
The planets orbit in an ellipse
The plants move faster when they are closer to the sun and slower when they are further from the sun
The farther a planet is from the sun the slower the orbit
(P2 = a3)
What is Kepler's 2nd law?
The planets orbit in an ellipse
The plants move faster when they are closer to the sun and slower when they are further from the sun
The farther a planet is from the sun the slower the orbit
(P2 = a3)
What is Kepler's 1st law?
The planets orbit in an ellipse
The plants move faster when they are closer to the sun and slower when they are further from the sun
The farther a planet is from the sun the slower the orbit
(P2 = a3)
Which planet takes longer to revolve around the Sun, Earth or Mars? Why?
Mars, it's closer to the Sun
Earth, it's farther from the Sun
Mars, it's farther from the Sun
Earth, it's closer to the Sun
What is gravity?
a force between objects that pushes them apart
a force between any two objects that pulls them together
a force that causes objects to remain at rest
a force that causes people to always fall in love...see what I did there?!!
What is true about the distance between a planet and the sun and the planet’s revolution around the Sun?
The closer the planet is to the sun, the slower it orbits.
The farther the planet is to the sun, the faster it orbits.
The farther the planet is to the sun, the brighter the sun is.
The closer the planet is to the sun, the faster it orbits.
The ___________ the planet is from the sun, the ____________ it takes to go around the sun.
closer, shorter
farther, shorter
farther, longer
closer, longer
Is the Sun a star?
yes
no
Which planet takes longer to revolve around the Sun, Earth or Mars? Why?
Mars, it's closer to the Sun
Earth, it's farther from the Sun
Mars, it's farther from the Sun
Earth, it's closer to the Sun
How does the mass of an object effect the gravitational attraction of an object?
The smaller the mass of the object the greater the gravitational force.
The mass of the object has no effect on the gravitational force
The greater the mass of the object the less the gravitational force.
The greater the mass of the object the greater the gravitational force.
