Front

What is Kepler's First Law of Planetary Motion?

Back

Planets move in elliptical orbits with the Sun at one focus.

Front

What does Kepler's Second Law state?

Back

A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Front

What is Kepler's Third Law of Planetary Motion?

Back

The square of the period of any planet is proportional to the cube of the semi-major axis of its orbit.

Front

What is the relationship between distance and gravitational force?

Back

The farther away two planets are, the less the gravitational force between them.
