Kepler's Laws Review

Where is the planet moving faster

• Position A to B
• Position B to C
• Position H to I
• Position I to J

A planet moves __________ when it is farthest from the sun.

• faster
• slower

Kepler's first law states that the orbits of the planets are oval in shape or 

• ellipses
• perfect circles

The farther away a planet is from the sun, the _______ it takes it to orbit the sun once. 

• longer
• shorter

Earth's orbit follows an elliptical path.

• Kepler's 1st law
• Kepler's 2nd law
• Kepler's 3rd law
• Nutation

When Earth orbits around the sun, it slows down when it is close to the sun. It speeds up its orbit when it is further from the sun. This is because the sun's gravity is stronger when you are closer to it.

• Kepler's 1st law
• Kepler's 2nd law
• Kepler's 3rd law
• Nutation

The amount of time it takes for a planet to orbit around the sun is it's _____

• axis length

• foci

• magnitude

• period

Which of Kepler's Laws states that "All planets move about the Sun in elliptical orbits, having the Sun as one of the foci"

• Kepler's 1st law

• Kepler's 2nd law

• Kepler's 3rd law

Which of Kepler's laws states that planets travel faster when they are close to the sun then they do when they are farther from the sun?

• Kepler's 1st law

• Kepler's 2nd law

• Kepler's 3rd law

What is true about the area between points A, B and the Sun, and the area between points H, I and the Sun?

• The area between A, B and the Sun is the largest.
• The area between H, I and the Sun is the largest
• Both areas are equal in size
• There is not enough information to determine the areas
