Kepler's Second Law

What is Kepler's Second Law of Planetary Motion?

• The speed of a planet is inversely proportional to its distance from the Sun

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

• The closer a planet is to the Sun, the slower it moves

• Planets move in perfect circles around the Sun

Explain how Kepler's Second Law relates to the speed of a planet in its orbit.

• The speed of a planet in its orbit is determined solely by its mass.

• The speed of a planet in its orbit is not constant but varies depending on its distance from the Sun.

• Kepler's Second Law states that planets move in perfect circles in their orbits.

• The speed of a planet in its orbit is constant regardless of its distance from the Sun.

How does Kepler's Second Law describe the equal area rule?

• Kepler's Second Law states that planets move in elliptical orbits

• Kepler's Second Law explains the relationship between a planet's distance from the Sun and its orbital speed

• Kepler's Second Law describes the gravitational force between the Sun and a planet

• Kepler's Second Law describes the equal area rule by stating that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

What is the significance of the equal area rule in Kepler's Second Law?

• The significance of the equal area rule in Kepler's Second Law is that it helps explain the varying speeds of planets in their orbits.

• It determines the color of the planets in their orbits.

• It predicts the exact time of day when a planet will reach its closest point to the sun.

• It influences the gravitational pull between planets.

Describe how the speed of a planet changes as it moves along its orbit according to Kepler's Second Law.

• The speed of a planet changes as it moves along its orbit according to Kepler's Second Law by being faster at perihelion and slower at aphelion.

• The speed of a planet changes as it moves along its orbit according to Kepler's Second Law by being faster at aphelion and constant at perihelion.

• The speed of a planet changes as it moves along its orbit according to Kepler's Second Law by being faster at aphelion and slower at perihelion.

• The speed of a planet changes as it moves along its orbit according to Kepler's Second Law by being constant throughout the orbit.

How does Kepler's Second Law help us understand the elliptical shape of planetary orbits?

• Kepler's Second Law is not related to the shape of planetary orbits

• Kepler's Second Law helps us explain how a planet's speed changes as it moves around the Sun, leading to the equal distribution of areas covered in equal times.

• Kepler's Second Law states that planets move at a constant speed around the Sun

• Kepler's Second Law explains the circular shape of planetary orbits

Discuss the implications of Kepler's Second Law on the motion of planets in the solar system.
