What does Kepler’s second law state about a planet's speed when it is closer to the sun?

Back

A planet moves faster when it is closer to the sun.

Front

According to Kepler’s Law of Periods, how do the speeds of planets relate to their distance from the star?

Back

Planets closer to their star move faster than those farther away.

What is Kepler's First Law?

Back

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

Front

What is the significance of the gravitational force in Kepler's laws?

Back

Gravitational force is the reason planets orbit the sun and follow Kepler's laws.

Front

What is the relationship between a planet's orbital period and its distance from the sun according to Kepler's Third Law?

Back

The square of a planet's orbital period is proportional to the cube of its average distance from the sun.
