Question 4 of 9

4. Question

Which of Kepler’s laws suggests that planets move faster when they are closer to the sun and slower when they are farther away?

Kepler’s first law

Kepler’s second law

Kepler’s third law

Kepler’s law of universal gravitation

Correct

Incorrect
Question 5 of 9

5. Question

Kepler’s third law establishes a relationship between a planet’s orbital period and its distance from the sun. How are these two factors related?

The orbital period is inversely proportional to the distance from the sun.

The orbital period is directly proportional to the square of the distance from the sun.

The square of the time period is proportional to the cube of the distance from the sun.

The time period is proportional to the cube of the distance from the sun.
