Understanding Kepler's Laws

What does Kepler's second law primarily describe?

• The shape of planetary orbits

• The speed of a planet in its orbit

• The distance between planets

• The gravitational pull of the Sun

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

• It decreases

• It increases

• It remains constant

• It stops

What is the significance of the perihelion in Kepler's second law?

• It is the point where the planet stops moving

• It is the point where the planet is closest to the Sun

• It is the point where the planet moves the slowest

• It is the point where the planet is farthest from the Sun

How does the speed of a planet change as its distance from the Sun increases?

• The speed becomes zero

• The speed remains the same

• The speed decreases

• The speed increases

What is the main takeaway from Kepler's second law regarding planetary motion?

• Planets stop moving at aphelion

• Planets have constant speed

• Planets move faster when closer to the Sun

• Planets move in perfect circles
