Kepler's third law is a relationship between an orbiting object's
A) gravitational force and mass.
B) acceleration and mass.
C) velocity and period.
D) period and semimajor axis.

Question

Quizplus · Accepted Answer

Kepler's third law relates an orbiting object's period (how long it takes to complete one orbit) to its semimajor axis (the longest radius of its elliptical orbit). It states that the square of the period is proportional to the cube of the semimajor axis. This relationship does not involve gravitational force or mass, acceleration, or velocity.
