Kepler's First Law states

• objects attract other objects with a force that is directly proportional to the product of their masses

• the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

• An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

• Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

Planets orbit the Sun in a shape called a(n) -

• circle

• ellipse

• focus

• perihelion

When a planet orbits the Sun, one of the foci of the elliptical orbit is ________, while the other is ______________.

• its moon, the Sun

• the perihelion, the Sun

• the Sun, its moon

• the Sun, empty space

• empty space, its moon

Where is the planet moving faster in its orbit?

• Position A to B

• Position B to C

• Position H to I

• Position I to J

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 larger.

• The area between H, I and the Sun is larger.

• Both areas are equal in size

• There is not enough information to determine the areas.

What has an eccentricity of zero?

• a straight line

• a squished ellipse

• a perfect circle

• an oval

Kepler's 2nd Law deals with 

• the shape of the planets' orbits
• the speed/area the planet travels 
• the length of time it takes the planet to orbit the sun
