In 1-2 sentences, explain how the shape of planetary orbits affects their orbital velocity. Include the proper law of planetary motion as part of your answer.(4 points)

Answer 1

The shape of planetary orbits, which are elliptical as described by Kepler's First Law of Planetary Motion, affects their orbital velocity because planets move faster when they are closer to the Sun (at periapsis) and slower when they are farther away (at apoapsis), in accordance with Kepler's Second Law, which states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This means that the varying distance from the Sun directly influences the speed of a planet's orbit.

Answer 2

shorter pls

Answer 3

Planetary orbits are elliptical, as per Kepler's First Law, and this shape causes faster orbital velocities at periapsis and slower velocities at apoapsis, in line with Kepler's Second Law, which states that equal areas are swept out in equal times.
