Kepler's Laws and The Law of Universal Gravitation

When the distance between two objects is doubled, in terms of $F_g,$ the force of gravity between them will be

• 
  

   $2F_g$  
  

•  $4F_g$  

•  $\frac{1}{2}F_g$  

•  $\frac{1}{4}F_g$

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

• circle
• ellipse
• focus
• perihelion

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

When a planet orbits the Sun, one of the foci of the elliptical orbit is 

• the axis
• the perihelion
• the center
• the Sun

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

What has an eccentricity of zero

• a straight line
• a large ellipse
• a circle
• a small ellipse

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
