D) By studying the behavior of pendulums.

Answer 1

Kepler developed his second law of planetary motion based on his observations of the motion of Mars along its elliptical orbit.

Step-by-step explanation:

Through his analysis of the motions of the planets, Kepler developed a series of principles, known as Kepler's three laws, which described the behavior of planets based on their paths through space. The first two laws of planetary motion were published in 1609 in The New Astronomy. Kepler initially assumed that the orbits of planets were circles, but after analyzing the data for Mars, he discovered that the planet's orbit had the shape of an ellipse.

Kepler's second law states that a planet moves faster when it is closer to the Sun and slower when it is farther away from the Sun. This law was derived from his observations of the motion of Mars along its elliptical orbit.
