Sort the items below into the bins corresponding to the correct Kepler\'s law of planetary motion.

Sort the items below into the bins corresponding to the correct Kepler's law of planetary motion.

Answer 1

Concepts and reason

The concept used to solve this problem is Kepler’s Laws of Planetary Motion.

Initially, use the concept of Kepler’s Laws of Planetary Motion to choose the correct item for Kepler’s First Law.

Then, use the concept of Kepler’s Laws of Planetary motion to choose the correct item for Kepler’s Second Law.

Finally, use the concept of Kepler’s Laws of Planetary Motion to choose the correct item for Kepler’s Third Law.

Fundamentals

Kepler’s First Law: It is also termed as the Law of orbits. It explains that all the planets move in an elliptical orbit with the sun at one focus.

Kepler’s Second Law: It is also termed as the Law of Areas. It explains a line that connects a planet to the sun which sweeps out equal areas in equal time.

Kepler’s Third Law: It is also termed as the Law of Periods. It explains the square of the period of any planet that is proportional to the cube of the semi-major axis of its orbits.

From Kepler’s Laws of Planetary motion, the Kepler’s First Law explains that the all the planets move in elliptical orbits with the sun located at one focus of a planet’s orbit.

From the Kepler’s Laws of Planetary motion, the Kepler’s Second Law explains that the planets sweep out equal areas in equal times and the planets are held in orbit around the sun by gravity.

From the Kepler’s Laws of Planetary motion, the Kepler’s Third Law explains that the planets move the fastest at perihelion and planets with larger orbits take more time to complete one orbit. The planet’s semi-major axis is related to its orbital period.

Ans:

The correct item for Kepler’s First Law is that the entire planets move in elliptical orbits with the sun located at one focus of a planet’s orbit.

The correct items for Kepler’s Second Law are that the planets sweep out equal areas in equal times and the planets are held in orbit around the sun by gravity.

The correct items for Kepler’s third Law are that the planets move the fastest at perihelion and planets with larger orbits take more time to complete one orbit. The planet’s semi-major axis is related to its orbital period.
