Question 11 • Physics

Which statement is supported by Kepler’s laws?

Answer
A
The closer a planet is to the Sun, the faster it moves.
B
As a planet moves away from the Sun, its gravitational force remains the same.
C
The farther a planet is from the Sun, the faster it moves.
D
As a planet moves away from the Sun, its gravitational force increases.

Explanation

Kepler’s second law says that a planet sweeps out equal areas in equal amounts of time. To do this, it must move faster when it is closer to the Sun and slower when it is farther away. Therefore, the supported statement is “The closer a planet is to the Sun, the faster it moves.”
