• circle

• ellipse

• focus

• perihelion

Where is the planet moving faster

• 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 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

Kepler's third law states the closer a planet is to its Sun, the shorter the planet's orbital period (year) and the farther a planet is from the Sun the longer the year. 

• True

• False

For any planet, the square of its ​ (a)   of revolution is directly proportional to the ​ (b)   of its average distance from the Sun.

• period

• cube

Kepler’s 2nd Law states that the area swept out by a planet’s motion will be the same regardless of where it is in its orbit. A comet moves much faster when it is closer to the Sun than when it is further out from the Sun. What is the primary cause in the change of the comet’s orbital velocity?

• Jupiter's gravitational field.

• The sun's solar wind.

• The sun's gravitational field.

• Saturn's magnetic field.

According to Kepler's 3rd law, the square of the time it takes for an object to orbit, T, is directly related to the cube of the distance, r, between the object and what it is orbiting.    
What this means is that if a satellite moves away from what it is orbiting,

• the larger the constant k is.

• the smaller the constant k is.

• the longer the orbital period is.

• the shorter the orbital period is.
