#32 Kepler's Laws

What shape are the orbits of planets according to Kepler's laws?

• Circular

• Elliptical

• Parabolic

• Hyperbolic

According to Kepler's second law, what happens to a planet's speed as it gets closer to the Sun?

• It decreases

• It remains constant

• It increases

• It stops

What is the relationship between a planet's orbital period (T) and its semi-major axis (a) according to Kepler's third law?

• T² = a³

• T = a²

• T³ = a²

• T² = a²

Which of the following planets has an orbital period of approximately 0.24 Earth years?

• Earth

• Venus

• Mercury

• Jupiter

Why does a line between a planet and the Sun sweep out equal areas during equal time periods, no matter the planet's distance from the Sun during its orbit?

• Because of the planet's constant speed

• Due to the gravitational pull of the Sun

• As a result of Kepler's Second Law

• Because of the planet's elliptical orbit

When a planet orbits the Sun, one of the foci of the elliptical orbit is 

• the axis
• the perihelion
• the center
• the Sun
