How did Kepler develop his second law of motion?
Responses
He made accurate measurements of the positions of all the planets over many years.
He compared data of planetary motion at different times along orbits.
He used a telescope to carefully follow and time the orbital motion of Mars.
He invented a telescope that was strong enough to view all planets of the solar system along their orbits.
The correct response is: He compared data of planetary motion at different times along orbits.
The correct response is:
He compared data of planetary motion at different times along orbits.
Kepler developed his second law of motion by comparing data of planetary motion at different times along their orbits. He found that planets move faster when they are closer to the Sun and slower when they are farther away. This relationship between a planet's distance from the Sun and its speed along its orbit is known as Kepler's second law of motion.
